The company’s first project in the state will deliver fast, reliable internet to nearly 300K addresses across Chicagoland

Lumos, a leading 100% Fiber Optic Internet provider and network infrastructure leader, is proud to announce that the team broke ground on its 3,000-mile fiber installation in DuPage and Cook Counties, a milestone in the company’s expansion into the Illinois market.

Lumos, now part of T-Mobile Fiber, will deploy the latest fiber optic technology to support small businesses, boost connectivity on multifamily properties and meet the increasing digital demands of residents and families. The company’s state-of-the-art fiber network will serve more than 20 Chicagoland communities, including Naperville, Schaumburg, Hoffman Estates, Wheaton and Bolingbrook.

“We’re eager to get to work and begin installation of Lumos’s Fiber Optic network across Chicago communities,” said Brian Stading, CEO of Lumos. "This investment will deliver faster, more dependable internet to businesses and communities across Chicagoland, fueling economic growth and enhancing everyday life for years to come.”

The Illinois groundbreaking celebrates Lumos’s entrance into its tenth state of operation, underscoring the company’s rapid growth and commitment to expanding digital opportunity. The planned network will reach portions of Illinois currently lacking a fiber provider, bringing critical connectivity to underserved and unserved neighborhoods.

As Lumos builds the fiber network, residents can sign up for T-Mobile Fiber — delivering fast, reliable internet with plans starting at just $55/month for 500 Mbps with Fiber AutoPay and a T-Mobile voice line. Every plan includes unlimited data, ultra-fast symmetrical speeds — and no annual contracts, equipment fees or installation charges. And only T-Mobile Fiber customers get the Un-carrier experience including a 5-year price guarantee (exclusions like taxes and fees apply), on top of benefits like weekly perks on dining, gas and entertainment with T-Mobile Tuesdays, free season-long subscriptions to MLB.TV and MLS Season Pass and more. Residents can find more information and confirm T-Mobile Fiber availability in their area at fiber.t-mobile.com.

Leaders throughout Cook & DuPage Counties highlight the project’s importance:

“Lumos Fiber's arrival in Chicagoland marks another step forward in our commitment to strengthening infrastructure and ensuring every resident has access to fast, reliable internet. Whether you’re logging in for work, running a business, or relaxing with a favorite series, a quality internet connection is directly connected to your quality of life,” said Roselle Mayor David Pileski. “Having more competition in the fiber internet market means our residents will have more high-speed internet options, keeping Roselle connected and ready for the future.”

“In our speed of light society, and especially in a community like Naperville, offering access to fiber-to-the-home is essential,” said Naperville Mayor Scott Wehrli. “Over 25% of our residents work from home, including in down-to-the-millisecond industries where this level of connectivity is a must-have. We have a history of working with telecom companies for decades to provide options to residents and businesses so that they can choose whatever solution works best for them and meets their needs, and welcoming Lumos and their fiber offering into the mix is a very important next step.”

“The installation of a new fiber-optic network in Woodridge will provide our neighbors and businesses with another option for high-speed internet and reliable communication services,” said Woodridge Mayor Gina Cunningham. “Expanding access and increasing choice supports our community’s ongoing efforts to stay connected and plan for the future.”

Engineering for the expansion is underway, and residents will receive updates by mail as construction begins in their area. To learn more about the build process, visit www.lumosfiber.com/new-construction.
