Press Release

Bellevue, November 8, 2005

T-MOBILE USA HITS 20 MILLION CUSTOMER MILESTONE IN THE THIRD QUARTER 2005, WHILE ACHIEVING RECORD OIBDA MARGIN

•      1.06 million net new customers added in Q3 2005, breaking 20 million total customer milestone

•      $1.17 billion in Operating Income Before Depreciation and Amortization (OIBDA) in Q3 2005, up 48% from Q3 2004

•      OIBDA margin of 34% achieved in the quarter

•      Q3 2005 net income of $458 million, up more than 80% from Q3 2004

•      T-Mobile awarded highest honors for the second consecutive year in both the J.D. Power and Associates 2005 Wireless Regional Customer Satisfaction Index Study and the 2005 Wireless Retail Satisfaction Performance Study

In the third quarter of 2005, T-Mobile USA added 1.06 million net new customers, up from 972,000 customers added in the second quarter of 2005 and 901,000 added in the third quarter of 2004.  Approximately 68% of the growth in the third quarter of 2005 came from new postpay customers, which currently comprise over 86% of T-Mobile USA’s total customer base.  Approximately 32% of the growth came from new prepaid customers, a similar proportion as in the second quarter of 2005, continuing to reflect the success of T-Mobile USA’s attractive prepaid offering.

T-Mobile’s commitment to providing world-class customer service continued to be recognized in independent studies in the third quarter. During the third quarter T-Mobile earned highest honors for the second consecutive year in both

the J.D. Power and Associates 2005 Wireless Regional Customer Satisfaction Index Study and the 2005 Wireless Retail Satisfaction Performance Study.

“Our employees and Deutsche Telekom’s shareholders have much to be pleased about,” said T-Mobile USA President and CEO Robert Dotson.  “In the third quarter, we hit the key 20 million customer milestone, adding more than one million new net customers.  We achieved this strong customer growth while also delivering a solid OIBDA margin of 34%, a result that reflects our disciplined approach to managing costs.  For the second year in a row we captured top Overall Customer Satisfaction awards from J.D. Power and Associates.  Bottom line - our Get More Minutes, Features and Service initiatives continue to resonate with our customers.”

René Obermann, CEO of T-Mobile International and member of the board of management of Deutsche Telekom (NYSE: DT), stated,  “T-Mobile USA once again delivered outstanding results and continues to be a top driver of growth across our entire business.  Their continued strong operating performance has made the US operations an integral part to Deutsche Telekom’s overall success.”

T-Mobile USA reported OIBDA of $1.17 billion in the third quarter of 2005 compared to $1.08 billion in the second quarter of 2005 and $788 million in the third quarter of 2004. T-Mobile USA’s net income for the third quarter of 2005 was $458 million, up from $387 million in the second quarter of 2005 and $254 million in the third quarter of 2004.

T-Mobile USA service revenues, which consist of postpay, prepaid, roaming and other service revenues, were $3.15 billion in the third quarter of 2005, up from $3.04 billion in the second quarter of 2005 and $2.61 billion in the third quarter

of 2004.  Affiliate and other revenues were $235 million in the third quarter of 2005, down from $269 million in the second quarter of 2005 and up from $35 million in the third quarter of 2004. These revenues include Wi-Fi revenues, co-location rental income, and revenues from the usage of our network in California, Nevada, and New York by Cingular’s customers who have not yet transitioned to Cingular’s own network. Total revenues, including service, equipment, and other revenues were $3.80 billion in the third quarter of 2005.

Average Revenue Per User (“ARPU,” as defined in the footnotes to the Selected Data, below) was $53 in the third quarter of 2005, down slightly from $54 in the second quarter of 2005 and $55 in the third quarter of 2004. Data services revenue continued to grow in the third quarter, and now represents 8.8% of postpay ARPU, compared to 8.2% in the second quarter of 2005 and 5.6% in the third quarter of 2004.  Key to data services revenue growth was a net increase of 68,000 BlackBerry customers in the quarter, bringing the total number of BlackBerry users to 662,000. The launch of our EDGE network in the third quarter of 2005 and continued Wi-Fi hot-spot expansion underlines our ongoing commitment to provide customer focused data services.

Postpay churn averaged 2.4% per month in the third quarter of 2005, down from 2.6% in the third quarter of 2004, and up slightly from the 2.3% in the second quarter of 2005.  Blended churn, including both postpay and prepaid customers, was 2.9% in the third quarter of 2005, compared to 2.8% achieved in the second quarter of 2005 and slightly below 3.0% in the third quarter of 2004. While churn decreased year on year in the third quarter, it increased slightly from the second quarter of 2005 due to the seasonal impact of more customers reaching their one-year service anniversaries in the third quarter of the year.

The average cost of acquiring a customer, Cost Per Gross Add (“CPGA”, as defined in the footnotes to the Selected Data, below) was $271 in the third quarter of 2005, down from $310 in the second quarter of 2005 and $301 in the third quarter of 2004.  The quarter on quarter improvement is due to a reduction in handset subsidies, while at the same time achieving solid customer growth.

The average cash cost of serving customers, Cash Cost Per User (“CCPU”, as defined in the footnotes to the Selected Data, below), was $24.65 per customer per month in the third quarter of 2005, down from $25.66 in the second quarter of 2005 and up slightly from $24.23 in the third quarter of 2004.  The increase in CCPU relative to 2004 reflects the inclusion in our results of all the costs to operate the networks in California, Nevada and New York associated with the acquisition of full ownership of those networks at the beginning of 2005, including the costs of providing transitional network services to Cingular’s customers. The year on year increase in CCPU also reflects the change in our accounting for operating leases in the fourth quarter of 2004 – see further discussion in the footnotes to the Selected Data, below.

Capital expenditures were $585 million in the third quarter of 2005, compared with $815 million in the second quarter of 2005 and $453 million in the third quarter of 2004.  Capital expenditures in the third quarter of 2004 did not include $124 million related to the network joint venture with Cingular, which was terminated in the first quarter of 2005.  T-Mobile USA added almost 1,000 new cell sites in the third quarter of 2005, bringing the total number of cell sites to nearly 32,000. During the first nine months of 2005 we added more than 2,400 new cell sites, reflecting our continued commitment to improving network coverage and quality.

This press release includes non-GAAP financial measures. The non-GAAP financial measures should be considered in addition to, but not as a substitute for, the information provided in accordance with GAAP. Reconciliations from the non-GAAP financial measures to the most directly comparable GAAP financial measures are provided below following Selected Data and the financial statements.

T-Mobile USA, Inc. (“T-Mobile USA”) is the U.S. operation of T-Mobile International AG & Co. KG (“T-Mobile International”), the mobile communications subsidiary of Deutsche Telekom AG (“Deutsche Telekom”) (NYSE: DT). In order to provide comparability with the results of other U.S. wireless carriers all financial amounts are in USD and are based on accounting principles generally accepted in the United States (“GAAP”).  T-Mobile USA results are included in the consolidated results of Deutsche Telekom, but differ from the information contained herein as Deutsche Telekom reports financial results in accordance with International Financial Reporting Standards (IFRS).

SELECTED DATA FOR T-MOBILE USA

Since all companies do not calculate these figures in the same manner, the information contained in this press release may not be comparable to similarly titled measures reported by other companies.

(1)   Average Revenue Per User (“ARPU”) represents the average monthly service revenue we earn from our customers.  ARPU is calculated by dividing service revenues for the specified period by the average customers during the period, and further dividing by the number of months in the period.  We believe ARPU provides useful information to evaluate the recurring revenues generated from our customer base.

Service revenues include postpay, prepaid, and roaming and other service revenues, and do not include equipment sales, affiliate and other revenues. Revenues from our Wi-Fi

business, co-location rental income, and revenues for network usage by Cingular customers who have not yet transitioned from the former joint venture networks in California, Nevada, and New York, are therefore not included in ARPU.

(2)   As a result of financial statement restatements by numerous U.S. public companies and publication of a letter by the Chief Accountant of the SEC to the American Institute of Certified Public Accountants on February 7, 2005, clarifying the interpretation of existing US GAAP accounting literature applicable to certain operating leases and leasehold improvements, T-Mobile USA changed its accounting for operating leases and recorded a cumulative adjustment representing a net charge to net income of $143 million in the fourth quarter of 2004, of which $71 million related to the years 2001 through 2003. The net cumulative adjustment was comprised of a $200 million increase in rent expense based primarily on rent escalation clauses related to future renewal periods of cell site leases; an increase of $33 million in the equity loss from the network sharing venture with Cingular also related to cell site leases; a reduction of $53 million in depreciation expense to adjust the depreciable life of leasehold improvements; and a reduction of $36 million in the loss provision related to dissolution of the network sharing joint venture with Cingular. Financial results for 2004 and prior periods have not been restated.

The following table provides the impact of the cumulative adjustments as it relates to the quarterly results in 2004 as if restated.

(3)   The average cash cost of serving customers, or Cash Cost Per User (“CCPU”) is a non-GAAP financial measure and includes all network and general and administrative costs as well as the subsidy loss on equipment (handsets and accessories) sales unrelated to customer acquisition.  This measure is calculated as a per month average by dividing the total costs for the specified period by the average total customers during the period and further dividing by the number of months in the period. We believe that CCPU, which is a measure of the costs of serving a customer, provides relevant and useful information to our investors and is used by our management to evaluate the operating performance of our business.

(4)   Cost Per Gross Add (“CPGA”) is a non-GAAP financial measure and is calculated by dividing the costs of acquiring a new customer, consisting of customer acquisition costs plus the subsidy loss on equipment (handsets and accessories) sales related to customer acquisition for the specified period, divided by gross customers added during the period. We believe that CPGA, which is a measure of the cost of acquiring a customer, provides relevant and useful information to our investors and is used by our management to evaluate the operating performance of our business.

(5)   OIBDA is a non-GAAP financial measure, which we define as operating income before depreciation and amortization. In a capital-intensive industry such as wireless telecommunications, we believe OIBDA, as well as the associated percentage margin calculation, to be meaningful measures of our operating performance. OIBDA should not be construed as an alternative to operating income or net income as determined in accordance with GAAP, as an alternative to cash flows from operating activities as determined in accordance with GAAP or as a measure of liquidity. We use OIBDA as an integral part of our planning and internal financial reporting processes, to evaluate the performance of our senior management and to compare our performance with that of many of our competitors. We believe that operating income is the financial measure calculated and presented in accordance with GAAP that is the most directly comparable to OIBDA.

(6)   2004 amounts exclude our investment to fund capital expenditures in the network sharing joint venture with Cingular Wireless LLC (“Cingular”). 2005 amounts include capital expenditures in the coverage areas previously served by the venture.

(7)   2004 amounts include sites in New York, California and Nevada previously owned and operated by our network sharing joint venture.

(8)   OIBDA margin is a non-GAAP financial measure, which we define as OIBDA (as described in note 5 above) divided by total revenues less equipment sales.
