        We may use this Prospectus from time to time to offer, on a continuous, delayed or periodic basis, senior and subordinated debt securities consisting of debentures, notes, bonds and/or other evidences of indebtedness, which we refer to collectively as "debt securities." We may offer such debt securities in one or more series in amounts, at prices and on terms to be determined at the time of sale.

        The debt securities are expected to be issued only in registered form. All or a portion of the debt securities of any series may be issued to a depository as a global security and may be exchangeable for physical securities only under limited conditions.

        We may sell debt securities to or through underwriters or dealers, and also may sell debt securities to other purchasers directly or through agents. An accompanying Prospectus Supplement will set forth the names of any underwriters, dealers or agents involved in the sale of the debt securities offered hereby, the principal amounts, if any, to be purchased by underwriters and the compensation of such underwriters, dealers or agents.

The relevant Prospectus Supplement will contain information, if applicable, as to whether the debt securities offered will be listed for trading on any securities exchange or other market.

        Investing in our debt securities involves risk. See "Risk Factors" on page 7 of this Prospectus.

All statements, other than statements of historical facts, are forward-looking statements. The words "believes," "anticipates," "estimates," "expects," "plans," "intends," "projects" and similar expressions are intended to identify these forward-looking statements, but are not the exclusive means of identifying them.

Such risks, uncertainties and other factors include those set forth below and the risks included or incorporated by reference under "Risk Factors." However, such factors are not necessarily all of the important factors that could cause actual results, performance or achievements to differ materially from those expressed in, or implied by, the forward-looking statements contained in this Prospectus and the documents incorporated by reference herein. Other unknown or unpredictable factors also could have material adverse effects on future results, performance or achievements. TDS undertakes no obligation to update publicly any forward-looking statements whether as a result of new information, future events or otherwise. You should carefully consider the Risk Factors included or incorporated by reference herein, the following factors and other information contained in, or incorporated by reference into, this Prospectus to understand the material risks relating to TDS' business.

•

Intense competition in the markets in which TDS operates could adversely affect TDS' revenues or increase its costs to compete.



•

A failure by TDS to successfully execute its business strategy (including planned acquisitions, divestitures and exchanges) or allocate resources or capital could have an adverse effect on TDS' business, financial condition or results of operations.



•

Uncertainty in TDS' future cash flow and liquidity or in the ability to access capital, deterioration in the capital markets, other changes in TDS' performance or market conditions, changes in TDS' credit ratings or other factors could limit or restrict the availability of financing on terms and prices acceptable to TDS, which could require TDS to reduce its construction, development or acquisition programs, reduce the acquisition of spectrum licenses, and/or reduce or cease share repurchases and/or the payment of dividends.



•

TDS has a significant amount of indebtedness which could adversely affect its financial performance and in turn adversely affect its ability to make payments on its indebtedness, comply with terms of debt covenants and incur additional debt.



•

Changes in roaming practices or other factors could cause TDS' roaming revenues to decline from current levels, roaming expenses to increase from current levels and/or impact TDS' ability to service its customers in geographic areas where TDS does not have its own network, which could have an adverse effect on TDS' business, financial condition or results of operations.



•

A failure by TDS to obtain access to adequate radio spectrum to meet current or anticipated future needs and/or to accurately predict future needs for radio spectrum could have an adverse effect on TDS' business, financial condition or results of operations.



•

To the extent conducted by the Federal Communications Commission ("FCC"), TDS may participate in FCC auctions of additional spectrum in the future directly or indirectly and, during certain periods, will be subject to the FCC's anti-collusion rules, which could have an adverse effect on TDS.

•

TDS' assets are concentrated primarily in the U.S. telecommunications industry. Consequently, its operating results may fluctuate based on factors related primarily to conditions in this industry.



•

TDS' smaller scale relative to larger competitors that may have much greater financial and other resources than TDS could cause TDS to be unable to compete successfully, which could adversely affect its business, financial condition or results of operations.



•

Changes in various business factors, including changes in demand, customer preferences and perceptions, price competition, churn from customer switching activity and other factors, could have an adverse effect on TDS' business, financial condition or results of operations.



•

Advances or changes in technology could render certain technologies used by TDS obsolete, could put TDS at a competitive disadvantage, could reduce TDS' revenues or could increase its costs of doing business.



•

Complexities associated with deploying new technologies present substantial risk and TDS' investments in unproven technologies may not produce the benefits that TDS expects.



•

TDS receives regulatory support and is subject to numerous surcharges and fees from federal, state and local governments, and the applicability and the amount of the support and fees are subject to great uncertainty.



•

Performance under device purchase agreements could have a material adverse impact on TDS' business, financial condition or results of operations.



•

Changes in TDS' enterprise value, changes in the market supply or demand for wireless licenses, wireline or cable markets or IT service providers, adverse developments in the businesses or the industries in which TDS is involved and/or other factors could require TDS to recognize impairments in the carrying value of its licenses, goodwill, franchise rights and/or physical assets.



•

Costs, integration problems or other factors associated with acquisitions, divestitures or exchanges of properties or licenses and/or expansion of TDS' businesses could have an adverse effect on TDS' business, financial condition or results of operations.



•

TDS offers customers the option to purchase certain devices under installment contracts which, compared to fixed-term service contracts, includes risks that TDS may possibly incur greater churn, lower cash flows, increased costs and/or increased bad debts expense due to differences in contract terms, which could have an adverse impact on TDS' financial condition or results of operations.



•

A failure by TDS to complete significant network construction and systems implementation activities as part of its plans to improve the quality, coverage, capabilities and capacity of its networks and support systems could have an adverse effect on its operations.



•

Difficulties involving third parties with which TDS does business, including changes in TDS' relationships with or financial or operational difficulties of key suppliers or independent agents

and third party national retailers who market TDS' services, could adversely affect TDS' business, financial condition or results of operations.

TDS has significant investments in entities that it does not control. Losses in the value of such investments could have an adverse effect on TDS' financial condition or results of operations.

TDS has experienced and, in the future, expects to experience cyber-attacks or other breaches of network or information technology security of varying degrees on a regular basis, which could have an adverse effect on TDS' business, financial condition or results of operations.



•

The market price of TDS' Common Shares is subject to fluctuations due to a variety of factors.



•

Changes in facts or circumstances, including new or additional information, could require TDS to record charges in excess of amounts accrued in the financial statements, which could have an adverse effect on TDS' business, financial condition or results of operations.



•

Disruption in credit or other financial markets, a deterioration of U.S. or global economic conditions or other events could, among other things, impede TDS' access to or increase the cost of financing its operating and investment activities and/or result in reduced revenues and lower operating income and cash flows, which would have an adverse effect on TDS' business, financial condition or results of operations.



•

Settlements, judgments, restraints on its current or future manner of doing business and/or legal costs resulting from pending and future litigation could have an adverse effect on TDS' business, financial condition or results of operations.



•

The possible development of adverse precedent in litigation or conclusions in professional studies to the effect that radio frequency emissions from wireless devices and/or cell sites cause harmful health consequences, including cancer or tumors, or may interfere with various electronic medical devices such as pacemakers, could have an adverse effect on TDS' wireless business, financial condition or results of operations.



•

Claims of infringement of intellectual property and proprietary rights of others, primarily involving patent infringement claims, could prevent TDS from using necessary technology to provide products or services or subject TDS to expensive intellectual property litigation or monetary penalties, which could have an adverse effect on TDS' business, financial condition or results of operations.



•

Certain matters, such as control by the TDS Voting Trust and provisions in the TDS Restated Certificate of Incorporation, may serve to discourage or make more difficult a change in control of TDS.



•

Any of the foregoing events or other events could cause revenues, earnings, capital expenditures and/or any other financial or statistical information to vary from TDS' forward-looking estimates by a material amount.

DESCRIPTION OF DEBT SECURITIES

        We expect to issue the senior debt securities under the Indenture dated November 1, 2001 (the "Senior Indenture") between TDS and The Bank of New York Mellon Trust Company, N.A. (formerly known as The Bank of New York Trust Company, N.A., as successor to BNY Midwest Trust Company), as Trustee, which has been incorporated by reference as an exhibit to the Registration Statement of which this Prospectus is a part. We expect to issue the subordinated debt securities under the Indenture, dated as of September 16, 2013 (the "Subordinated Indenture" and, together with the Senior Indenture, the "Indentures") between TDS and The Bank of New York Mellon Trust Company, N.A., as Trustee, which has been incorporated by reference as an exhibit to the Registration Statement of which this Prospectus is a part. The following is a summary of the material terms of the Senior Indenture and the Subordinated Indenture.

        The statements contained in this Prospectus relating to the Indentures and the debt securities we may issue are summaries and are subject to, and are qualified in their entirety by reference to, all provisions of the Indentures (including those terms made a part of the Indentures by reference to the Trust Indenture Act of 1939, as amended (the "Trust Indenture Act")) and the other instruments defining the rights of holders of specific debt securities to be filed with the SEC at the time that such debt securities are issued. You should read the Indentures and such other documents for information that may be important to you before you buy any debt securities.

General Terms of the Indentures

        The debt securities that we may issue under the Indentures will be our direct obligations and may include debentures, notes, bonds and other evidences of indebtedness.

        The Indentures do not limit the aggregate principal amount of debt securities, secured or unsecured, which we may issue under the Indentures or otherwise.

        We may issue debt securities under the Indentures from time to time in one or more series or tranches thereof, as authorized by a resolution of our board of directors and as set forth in a company order or one or more supplemental indentures creating such series.

        Unless otherwise indicated in the applicable Prospectus Supplement, the Indentures also permit us to increase the principal amount of any series of debt securities previously issued and to issue such increased principal amount.

        The debt securities may be denominated and payable in foreign currencies or units based on or relating to foreign currencies.

        We will describe any special United States federal income tax considerations applicable to the debt securities in the Prospectus Supplement relating to those debt securities.

        Senior debt securities issued under the Senior Indenture are expected to be unsecured obligations of TDS and to rank pari passu with all other unsecured debt of TDS. However, because TDS is a holding company, the right of TDS, and hence the right of the creditors of TDS (including the holders of senior debt securities), to participate in any distribution of the assets of any subsidiary upon its liquidation or reorganization or otherwise is necessarily subject to the prior claims of creditors of such subsidiary, except to the extent that claims of TDS as a creditor of such subsidiary may be recognized.

        Subordinated debt securities will be subordinated and junior in right of payment to the prior payment in full of all of the senior debt of TDS, including the senior debt securities. We will state in the applicable prospectus supplement relating to any subordinated debt securities the subordination terms of the securities as well as the aggregate amount of outstanding indebtedness, as of the most recent practicable date, that by its terms would be senior to the subordinated debt securities.

9

---

Table of Contents

        In addition, the ability of TDS to make payments of principal and interest on the debt securities will be dependent upon the payment to it by its subsidiaries of dividends, loans or advances. As described in the notes to the TDS financial statements incorporated by reference in this Prospectus, such payments by TDS' regulated telephone company subsidiaries may be subject to regulatory restrictions.

        There are no restrictions in the Indentures against TDS or its subsidiaries incurring secured or unsecured indebtedness or issuing secured or unsecured debt securities under the Indentures or other indentures.

        The Indentures are subject to, and governed by, the Trust Indenture Act.

Designation of Terms of Securities

        We will execute a company order and/or a supplemental indenture relating to a particular series of debt securities if and when we issue any debt securities.

        We will describe the particular terms of each series of debt securities in a Prospectus Supplement relating to that series.

        We can issue these debt securities in one or more series with the same or various maturities, at par, at a premium, or at a discount.

        We will set forth in a Prospectus Supplement relating to any series of debt securities being offered, the aggregate principal amount and the following terms of the debt securities:

•

any limitations on the aggregate principal amount of the debt securities of any series;

whether the amount of payment of principal of and premium, if any, or interest, if any, on such debt securities may be determined with reference to an index, formula or other method, or based on a coin or currency other than that in which the debt securities are stated to be payable;



•

any addition to, or modification or deletion of, any covenants or terms to the applicable Indenture, including events of default with respect to the debt securities of the series;

the terms and conditions, if any, pursuant to which the debt securities of the series are secured;



•

whether the debt securities of the series will be exchangeable into other securities and, if so, the terms and conditions upon which such securities will be exchangeable; and

any other terms of such series not inconsistent with the applicable Indenture.

        We may issue debt securities at a discount below their stated principal amount and provide for less than the entire principal amount of the debt securities to be payable upon declaration of acceleration of maturity. In that event, we will describe any material federal income tax considerations and other material considerations in the applicable Prospectus Supplement.

Form, Exchange, Registration and Transfer

        Debt securities in definitive form will be issued as registered securities without coupons in denominations of $1,000, unless otherwise specified in an accompanying Prospectus Supplement, and will be authenticated by the Trustee.

        You may present debt securities for registration of transfer, with the form of transfer endorsed thereon duly executed, or exchange, at the office of the security registrar, without service charge and upon payment of any taxes and other governmental charges.

        Such transfer or exchange will be effected upon TDS or the security registrar being satisfied with the documents of title and identity of the person making the request.

Table of Contents

        We may change the securities registrar and the place for registration of transfer and exchange of the debt securities and may designate one or more additional places for such registration and exchange.

•

register the transfer of or exchange any debt securities or portions thereof called for redemption in whole or in part.

Payment and Paying Agents

        You will receive payment of principal of and premium, if any, on any debt security only against surrender by you to the paying agent of such debt security.

        Principal of and any premium and interest on any debt security will be payable at the office of such paying agent or paying agents as we may designate from time to time.

        It is expected that the Trustee will act as paying agent with respect to debt securities. We may at any time designate additional paying agents or rescind the designation of any paying agents or approve a change in the office through which any paying agent acts.

        All moneys paid by us to a paying agent for the payment of the principal of and premium, if any, or interest, if any, on any debt securities that remain unclaimed at the end of two years after such principal, premium, if any, or interest will have become due and payable, subject to applicable law, will be repaid to us and the holder of such debt security will thereafter look only to us for payment thereof.

Book-Entry Debt Securities

        Except under the circumstances described below, the debt securities may be issued in whole or in part in the form of one or more global debt securities that will be deposited with, or on behalf of, a depository as we may designate and registered in the name of a nominee of such depository.

        It is expected that The Depository Trust Company will be the designated depository. Information about the designated depository will be set forth in the Prospectus Supplement.

        Book-entry debt securities represented by a global security will not be exchangeable for certificated notes and, except as set forth below or in the Prospectus Supplement, will not otherwise be issuable as certificated notes. Except as set forth below or in the Prospectus Supplement, owners of beneficial interests in a global security will not be entitled to have any of the individual book-entry debt securities represented by a global security registered in their names, will not receive or be entitled to receive physical delivery of any such book-entry security and will not be considered the owners thereof under the applicable Indenture, including, without limitation, for purposes of consenting to any amendment thereof or supplement thereto.

        So long as the depository, or its nominee, is the registered owner of a global security, such depository or such nominee, as the case may be, will be considered the sole owner of the individual book-entry debt securities represented by such global security for all purposes under the applicable Indenture.

        None of TDS, the Trustee nor any agent for payment on or registration of transfer or exchange of any global security will have any responsibility or liability for any aspect of the depository's records relating to or payments made on account of beneficial interests in such global security or for maintaining, supervising or reviewing any records relating to such beneficial interests.

Table of Contents

        Payments of principal of and premium, if any, and any interest on individual book-entry debt securities represented by a global security will be made to the depository or its nominee, as the case may be, as the owner of such global security.

        If the designated depository is at any time unwilling or unable to continue as depository and a successor depository is not appointed, we will issue individual certificated notes in exchange for the global note representing the corresponding book-entry debt securities.

        In addition, we may at any time and in our sole discretion determine not to have any debt securities represented by the global security and, in such event, will issue individual certificated notes in exchange for the global security representing the corresponding book-entry debt securities. In any such instance, an owner of a book-entry security represented by a global security will be entitled to physical delivery of individual certificated notes equal in principal amount to such book-entry security and to have such certificated notes registered in his or her name.

Modification of the Indentures

        With the Consent of Securityholders.    The Indentures contain provisions permitting TDS and the Trustee, with the consent of the holders of not less than a majority in aggregate principal amount of debt securities of each series that are affected by the modification, to modify such Indenture or any supplemental indenture affecting that series or the rights of the holders of that series of debt securities. However, no such modification, without the consent of the holder of each outstanding security affected thereby, may:

•

extend the fixed maturity of any debt securities of any series;



•

reduce the principal amount of any debt securities of any series;



•

reduce the rate or extend the time of payment of interest on any debt securities of any series;



•

reduce any premium payable upon the redemption of any debt securities of any series;



•

reduce the amount of the principal of a discount security that would be due and payable upon a declaration of acceleration of the maturity of any debt securities of any series;

reduce the percentage of holders of aggregate principal amount of debt securities which are required to consent to any such supplemental indenture; or



•

reduce the percentage of holders of aggregate principal amount of debt securities which are required to waive any default and its consequences.

        Without the Consent of Securityholders.    In addition, TDS and the Trustee may execute, without the consent of any holder of debt securities, any supplement to an Indenture for certain other usual purposes, including:

•

to evidence the succession of another person to TDS or a successor to TDS, and the assumption by any such successor of the covenants of TDS contained in such Indenture or otherwise established with respect to the debt securities;



•

to add to the covenants of TDS further covenants, restrictions, conditions or provisions for the protection of the holders of the debt securities of all or any series, and to make the occurrence, or the occurrence and continuance, of a default in any of such additional covenants, restrictions, conditions or provisions a default or an Event of Default with respect to such series permitting the enforcement of all or any of the several remedies provided in such Indenture;



•

to cure any ambiguity or to correct or supplement any provision contained in such Indenture or in any supplemental indenture which may be defective or inconsistent with any other provision contained in such Indenture or in any supplemental indenture, or to make such other provisions

Covenants

        Except as may be set forth in a Prospectus Supplement relating to a series of debt securities, the Indentures do not include any covenants restricting or providing any additional rights to holders of debt securities in the event of a merger or similar transaction involving TDS or the granting of security interests or a sale and leaseback transaction by TDS.

Events of Default

        The Indentures provide that any one or more of the following described events, which has occurred and is continuing, constitutes an "Event of Default" with respect to each series of debt securities issued pursuant to such Indenture:

•

failure for 30 days to pay interest on debt securities of that series when due and payable; or



•

failure for three business days to pay principal or premium, if any, on debt securities of that series when due and payable whether at maturity, upon redemption, pursuant to any sinking fund obligation, by declaration or otherwise; or



•

failure by TDS to observe or perform any other covenant (other than those specifically relating to another series) contained in such Indenture for 90 days after written notice to TDS from the Trustee or the holders of at least 33% in principal amount of the outstanding debt securities of that series; or



•

certain events involving bankruptcy, insolvency or reorganization of TDS; or



•

any other event of default provided for in a series of debt securities.

        Except as may otherwise be set forth in a Prospectus Supplement, the Trustee or the holders of not less than 33% in aggregate outstanding principal amount of any particular series of debt securities may declare the principal due and payable immediately upon an Event of Default with respect to such series. Holders of a majority in aggregate outstanding principal amount of such series may annul any such declaration and waive the default with respect to such series if the default has been cured and a sum sufficient to pay all matured installments of interest and principal otherwise than by acceleration and any premium has been deposited with the Trustee.

        The holders of a majority in aggregate outstanding principal amount of any series of debt securities have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee for that series.

        Subject to the provisions of the applicable Indenture relating to the duties of the Trustee in case an Event of Default will occur and be continuing, the Trustee will be under no obligation to exercise any of its rights or powers under such Indenture at the request or direction of any of the holders of the debt securities, unless such holders will have offered to the Trustee indemnity satisfactory to it.

        The holders of a majority in aggregate outstanding principal amount of any series of debt securities affected thereby may, on behalf of the holders of all debt securities of such series, waive any past default, except as discussed in the following paragraph.

        The holders of a majority in aggregate outstanding principal amount of any series of debt securities affected thereby may not waive a default in the payment of principal, premium, if any, or interest when due otherwise than by

•

acceleration, unless such default has been cured and a sum sufficient to pay all matured installments of interest and principal otherwise than by acceleration and any premium has been deposited with the Trustee; or



•

a call for redemption or any series of debt securities.

Table of Contents

        We are required to file annually with the Trustee a certificate as to whether or not we are in compliance with all the conditions and covenants under the Indentures.

Consolidation, Merger and Sale

        The Indentures do not contain any covenant that restricts our ability to merge or consolidate with or into any other corporation, sell or convey all or substantially all of our assets to any person, firm or corporation or otherwise engage in restructuring transactions.

        The successor corporation must assume due and punctual payment of principal or premium, if any, and interest on the debt securities.

Defeasance

        Debt securities of any series may be defeased in accordance with their terms and, unless the supplemental indenture or company order establishing the terms of such series otherwise provides, as set forth below.

        We at any time may terminate as to a series our obligations with respect to the debt securities of that series under any restrictive covenant which may be applicable to that particular series, commonly known as "covenant defeasance." All of our other obligations would continue to be applicable to such series.

        We at any time may also terminate as to a series substantially all of our obligations with respect to the debt securities of such series and the applicable Indenture, commonly known as "legal defeasance." However, in legal defeasance, certain of our obligations would not be terminated, including our obligations with respect to the defeasance trust and obligations to register the transfer or exchange of a security, to replace destroyed, lost or stolen debt securities and to maintain agencies in respect of the debt securities.

        We may exercise our legal defeasance option notwithstanding our prior exercise of any covenant defeasance option.

        If we exercise a defeasance option, the particular series will not be accelerated because of an event that, prior to such defeasance, would have constituted an Event of Default.

        To exercise either of our defeasance options as to a series, we must irrevocably deposit in trust with the Trustee or any paying agent money, certain eligible obligations as specified in the applicable Indenture, or a combination thereof, in an amount sufficient to pay when due the principal of and premium, if any, and interest, if any, due and to become due on the debt securities of such series that are outstanding.

        Such defeasance or discharge may occur only if, among other things, we have delivered to the Trustee an opinion of counsel stating that:

•

the holders of such debt securities will not recognize gain, loss or income for federal income tax purposes as a result of the satisfaction and discharge of the applicable Indenture with respect to such series, and



•

that such holders will realize gain, loss or income on such debt securities, including payments of interest thereon, in the same amounts and in the same manner and at the same time as would have been the case if such satisfaction and discharge had not occurred.

16

Table of Contents

        The amount of money and eligible obligations on deposit with the Trustee may not be sufficient to pay amounts due on the debt securities of that series at the time of an acceleration resulting from an Event of Default if:

•

we exercise our option to effect a covenant defeasance with respect to the debt securities of any series, and



•

the debt securities of that series are thereafter declared due and payable because of the occurrence of any Event of Default that results from an event, act or condition which does not arise from any covenant that has been defeased.

        In such event, we would remain liable for such payments.

Governing Law

        The Senior Indenture and the senior debt securities issued thereunder will be governed by the laws of the State of Illinois.

        The Subordinated Indenture and the subordinated debt securities issued thereunder will be governed by the laws of the State of New York.

Concerning the Trustee

        The Bank of New York Mellon Trust Company, N.A. (formerly known as The Bank of New York Trust Company, N.A., as successor to BNY Midwest Trust Company), the trustee under the Indentures, is an affiliate of The Bank of New York Mellon Corporation, which is one of a number of financial services organizations with which TDS and its subsidiaries, including U.S. Cellular, maintain ordinary banking and other financial relationships including, in certain cases, credit facilities. In connection therewith, we utilize or may utilize some of the banking and other services offered by The Bank of New York Mellon Corporation or its affiliates, including The Bank of New York Mellon Trust Company, N.A., in the normal course of business, including securities custody services.

        The Bank of New York Mellon Trust Company, N.A. (formerly known as The Bank of New York Trust Company, N.A., as successor to BNY Midwest Trust Company) is also trustee with respect to TDS' 6.625% Senior Notes due 2045, 6.875% Senior Notes due 2059, 7% Senior Notes due 2060 and 5.875% Senior Notes due 2061 that were issued under the Senior Indenture.

        The Bank of New York Mellon Trust Company, N.A. (formerly known as The Bank of New York Trust Company, N.A., as successor to BNY Midwest Trust Company) is also trustee with respect to U.S. Cellular's 6.95% Senior Notes due 2060, 6.70% Senior Notes due 2033, 7.25% Senior Notes due 2063 and 7.25% Senior Notes due 2064 that were issued under U.S. Cellular's senior indenture.

Information relating to Registration and Sale of Debt Securities

        TDS filed a Registration Statement on Form S-3 in order to register an indeterminate amount of senior and subordinated debt securities that may be issued pursuant to this Prospectus. The TDS board of directors has authorized the TDS pricing committee to have standing authority, among other things, to (i) authorize and cause to be filed with the SEC upon the issuance of securities under or upon the expiration or other termination of any Form S-3 Registration Statement, a new or amended Form S-3 Registration Statement, and to continue to successively renew or amend such registration statement upon subsequent expirations or other terminations, so that an indeterminate amount of debt securities continue to be registered, and (ii) from time to time, cause TDS to establish, issue and sell debt securities for debt refinancings, or issue and sell debt securities up to an aggregate initial offering price of $300,000,000 for purposes other than debt refinancings; provided that this authority can be revised by the TDS board of directors at any time or from time to time.

PLAN OF DISTRIBUTION

        We may sell debt securities being offered hereby:

•

directly to purchasers,



•

through agents,



•

through underwriters, and



•

through dealers.

        The distribution of the debt securities may be effected from time to time in one or more transactions at a fixed price or prices, which may be changed, at market prices prevailing at the time of sale, at prices related to such prevailing market prices or at negotiated prices.

Directly to Purchasers

        Offers to purchase debt securities may be solicited directly by TDS and sales thereof may be made by TDS directly to institutional investors or others. The terms of any such sales will be described in the Prospectus Supplement relating thereto. Any purchasers of such debt securities may be deemed to be underwriters within the meaning of the Securities Act with respect to any resale of those debt securities.

Agents

        Offers to purchase debt securities may be solicited by agents designated by TDS from time to time. Any such agent involved in the offer or sale of the debt securities in respect of which this Prospectus is delivered will be named, and any commissions payable by TDS to such agent will be set forth, in the Prospectus Supplement. Unless otherwise indicated in the Prospectus Supplement, any such agent will be acting on a best efforts basis for the period of its appointment. Any agent may be deemed to be an underwriter, as that term is defined in the Securities Act, of the debt securities so offered and sold.

Underwriters

        If underwriters are utilized in the sale, TDS will execute an underwriting agreement with such underwriters at the time of sale to them and the names of the underwriters and the terms of the transaction will be set forth in the Prospectus Supplement, which will be used by the underwriters to make resales of the debt securities in respect of which this Prospectus is delivered to the public. Any underwriters will acquire debt securities for their own account and may resell such debt securities from time to time in one or more transactions, including negotiated transactions, at fixed public offering prices or at varying prices determined at the time of sale. Debt securities may be offered to the public either through underwriting syndicates represented by managing underwriters, or directly by the managing underwriters. Only underwriters named in the Prospectus Supplement are deemed to be underwriters in connection with the debt securities offered thereby. If any underwriters are utilized in the sale of the debt securities, the underwriting agreement will provide that the obligations of the underwriters are subject to certain conditions precedent and that the underwriters with respect to a sale of debt securities will be obligated to purchase all such debt securities, if any are purchased.

Dealers

        If a dealer is utilized in the sale of the debt securities in respect of which this Prospectus is delivered, TDS will sell such debt securities to the dealer, as principal. The dealer may then resell such debt securities to the public at varying prices to be determined by such dealer at the time of resale. The name of the dealer and the terms of the transaction will be set forth in the Prospectus Supplement

18

---

Table of Contents

relating to those offers and sales. Any such dealer may be deemed to be an underwriter, as such term is defined in the Securities Act, of the debt securities so offered and sold.

Delayed Delivery Contracts

        If so indicated in the Prospectus Supplement, TDS will authorize agents and underwriters to solicit offers by certain institutions to purchase debt securities from TDS at the public offering price set forth in the Prospectus Supplement pursuant to delayed delivery contracts providing for payment and delivery on the date stated in the Prospectus Supplement.

        Each delayed delivery contract will be for an amount not less than, and unless TDS otherwise agrees the aggregate principal amount of debt securities sold pursuant to delayed delivery contracts shall be not less nor more than, the respective amounts stated in the Prospectus Supplement. Institutions with whom delayed delivery contracts, when authorized, may be made include commercial and savings banks, insurance companies, pension funds, investment companies, educational and charitable institutions and other institutions, but shall in all cases be subject to the approval of TDS.

        Delayed delivery contracts will not be subject to any conditions except that the purchase by an institution of the debt securities covered by its contract shall not at the time of delivery be prohibited under the laws of any jurisdiction in the United States to which such institution is subject.

        A commission indicated in the Prospectus Supplement will be paid to underwriters and agents soliciting purchases of debt securities pursuant to delayed delivery contracts accepted by TDS.

Remarketing

        Debt securities may also be offered and sold, if so indicated in the related Prospectus Supplement, in connection with a remarketing upon their purchase, in accordance with a redemption or repayment in connection with their terms, or otherwise, by one or more firms ("remarketing firms"), acting as principals for their own accounts or as agents for us and/or any selling shareholders. Any remarketing firm will be identified and the terms of its agreement, if any, with us and its compensation will be described in the related Prospectus Supplement. Remarketing firms may be deemed to be underwriters, as that term is defined in the Securities Act, in connection with the debt securities remarketed by them.

General Information

        Each series of debt securities will be a new issue and may have no established trading market. Unless otherwise specified in a related Prospectus Supplement, we will not be obligated to take any action to list any series of debt securities on an exchange or to otherwise facilitate a trading market for such debt securities. We cannot assure you that there will be any liquidity in the trading market for any of the debt securities. Agents, underwriters, dealers and remarketing firms may be customers of, engage in transactions with, or perform services for, us, our subsidiaries and/or any selling shareholders in the ordinary course of their businesses. The place, time of delivery and other terms of the sale of the offered debt securities will be described in the applicable Prospectus Supplement. In order to comply with the securities laws of some states, if applicable, the debt securities offered hereby will be sold in those jurisdictions only through registered or licensed brokers or dealers.

        In addition, in some states securities may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and complied with. Any underwriter may engage in over-allotment, stabilizing transactions, short-covering transactions and penalty bids in accordance with Regulation M under the Exchange Act. Over-allotment involves sales in excess of the offering size, which create a short position. Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum. Short-covering transactions involve purchases of the debt securities in the

19

---

Table of Contents

open market after the distribution is completed to cover short positions. Penalty bids permit the underwriters to reclaim a selling concession from a dealer when the debt securities originally sold by the dealer are purchased in a covering transaction to cover short positions. Those activities may cause the price of the debt securities to be higher than it would otherwise be. If commenced, the underwriters may discontinue any of the activities at any time.

        Agents, underwriters and dealers may be entitled under agreements entered into with TDS to indemnification by TDS against certain civil liabilities, including liabilities under the Securities Act, or to contribution with respect to payments which the agents, underwriters or dealers may be required to make in respect thereof. In addition, directors, officers and controlling persons of TDS are entitled under the TDS charter and bylaws and Delaware law to indemnification for civil liabilities, including liabilities under the Securities Act.

LEGAL MATTERS

        The validity of the debt securities offered hereby will be passed upon for TDS by the law firm of Sidley Austin LLP, Chicago, Illinois. The following persons are members of such firm: Walter C. D. Carlson, a trustee and beneficiary of a voting trust that controls TDS, the non-executive chairman of the board and member of the board of directors of TDS and a director of U.S. Cellular; William S. DeCarlo, the General Counsel of TDS and an Assistant Secretary of TDS and certain subsidiaries of TDS; and Stephen P.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 14.    Other Expenses of Issuance and Distribution

        The estimated fees and expenses to be incurred in connection with the registration, issuance and distribution of the debt securities being registered are:

Item 15.    Indemnification of Directors and Officers

        The Registrant's Restated Certificate of Incorporation contains a provision providing that no director or officer of the Registrant shall be personally liable to the Registrant or its stockholders for monetary damages for breach of fiduciary duty as a director or officer except for breach of the director's or officer's duty of loyalty to the Registrant or its stockholders, acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, unlawful payment of dividends, unlawful stock redemptions or repurchases and transactions from which the director or officer derived an improper personal benefit.

        The Restated Certificate of Incorporation also provides that the Registrant shall indemnify directors and officers of the Registrant, its consolidated subsidiaries and certain other related entities generally in the same manner and to the extent permitted by the Delaware General Corporation Law, as more specifically provided in the Restated Bylaws of the Registrant. The Restated Bylaws provide for indemnification and permit the advancement of expenses by the Registrant generally in the same manner and to the extent permitted by the Delaware General Corporation Law, subject to compliance with certain requirements and procedures specified in the Restated Bylaws. In general, the Restated Bylaws require that any person seeking indemnification must provide the Registrant with sufficient documentation as described in the Bylaws and, if an undertaking to return advances is required, to deliver an undertaking in the form prescribed by the Registrant and provide security for such undertaking if considered necessary by the Registrant. In addition, the Restated Bylaws specify that, except to the extent required by law, the Registrant does not intend to provide indemnification to persons under certain circumstances, such as where the person was not acting in the interests of the Registrant or was otherwise involved in a crime or tort against the Registrant.

        Under the Delaware General Corporation Law, directors and officers, as well as other employees or persons, may be indemnified against judgments, fines and amounts paid in settlement in connection with specified actions, suits or proceedings, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation—a "derivative action"), and against expenses (including attorney's fees) in any action (including a derivative action), if they acted in good faith and

II-1

---

Table of Contents

in a manner they reasonably believed to be in or not opposed to the best interests of the corporation and, with respect to any criminal action or proceeding, had no reasonable cause to believe their conduct was unlawful. However, in the case of a derivative action, a person cannot be indemnified for expenses in respect of any matter as to which the person is adjudged to be liable to the corporation unless and to the extent a court determines that such person is fairly and reasonably entitled to indemnity for such expenses.

        Delaware law also provides that, to the extent a director, officer, employee or agent of a corporation has been successful on the merits or otherwise in defense of any action or matter, the corporation must indemnify such party against expenses (including attorneys' fees) actually and reasonably incurred by such party in connection therewith.

        Expenses incurred by a director or officer in defending any action may be paid by a Delaware corporation in advance of the final disposition of the action upon receipt of an undertaking by or on behalf of such director or officer to repay such amount if it is ultimately determined that such party is not entitled to be indemnified by the corporation.

        The Delaware General Corporation Law provides that the indemnification and advancement of expenses provided thereby are not exclusive of any other rights granted by bylaws, agreements or otherwise, and provides that a corporation shall have the power to purchase and maintain insurance on behalf of any person, whether or not the corporation would have the power to indemnify such person under Delaware law.

        The Registrant has directors' and officers' liability insurance which provides, subject to certain policy limits, deductible amounts and exclusions, coverage for all persons who have been, are or may in the future be, directors or officers of the Registrant, against amounts which such persons must pay resulting from claims against them by reason of their being such directors or officers during the policy period for certain breaches of duty, omissions or other acts done or wrongfully attempted or alleged.

        Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been informed that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
