T-Mobile is officially a fiber provider after closing a deal to buy ISP Lumos, which serves markets in the Eastern US.

On Thursday, the carrier will launch a "T-Mobile Fiber Home Internet" business, which will initially focus on serving over 500,000 households in the US through Lumos’s existing network. This includes areas of Alabama, Florida, Georgia, Ohio, Illinois, Indiana, Kentucky, Virginia, North Carolina, and South Carolina.

Although 500,000 is a relatively small footprint, T-Mobile has ambitions to expand its fiber presence to 12 to 15 million US households by 2030. The company started piloting its fiber business in 2021, starting in New York City. 

The goal is offer the fiber business alongside T-Mobile's 5G Home Internet service, which has grown to nearly 7 million customers and currently has a waitlist for another 1 million+ would-be users. 5G Home Internet uses signals from cell towers to supply moderately fast broadband, making it an attractive option, especially for homes out of reach of traditional ground-based internet. However, T-Mobile’s fiber service can deliver even faster speeds at up to 2 Gigs. 

The company has now announced plans and pricing for T-Mobile Fiber:

  • Fiber 500, which delivers 500Mbps download speeds, will cost $75 per month with autopay, or $60 per month when purchased with a T-Mobile voice line.
  • Fiber 1 Gig will cost $90 per month with autopay or $75 per month with a T-Mobile line.
  • Fiber 2 Gig will cost $105 per month with autopay or $90 per month with a T-Mobile line.

To stand out from other providers, T-Mobile says its fiber business will also come with a five-year price guarantee while featuring "no monthly equipment fees, installation charges or annual contracts." The carrier is also offering an enticing, but limited-time 2 Gig deal for early adopters, called the Fiber Founders Club, that'll cost just $70 per month with a 10-year price guarantee.

No voice line is required either. But T-Mobile hasn’t listed the exact locations where the Fiber Founders Club deal will be offered yet.

When we brought up concerns about price hikes, the carrier also told PCMag that “nothing is changing for existing customers." Previously, Lumos offered the Fiber 500 and 1 Gig plans for $20 and $10 cheaper, respectively.

The carrier also said: “The 1Gig plan now includes additional benefits including Whole Home Wi-Fi mesh devices and weekly perks and freebies with T-Mobile Tuesdays, in addition to the guarantee the price of the plan won’t change for 5 years. We set our plan pricing to be competitive in the market and deliver customers the best possible value, which is what we’re doing with these new plans. And we’ll continue finding ways to give customers more to ensure they’re getting the best value alongside benefits they love at T-Mobile.”

My Experience

I've been a journalist for over 15 years. I got my start as a schools and cities reporter in Kansas City and joined PCMag in 2017, where I cover satellite internet services, cybersecurity, PC hardware, and more. I'm currently based in San Francisco, but previously spent over five years in China, covering the country's technology sector.

Since 2020, I've covered the launch and explosive growth of SpaceX's Starlink satellite internet service, writing 600+ stories on availability and feature launches, but also the regulatory battles over the expansion of satellite constellations, fights with rival providers like AST SpaceMobile and Amazon, and the effort to expand into satellite-based mobile service. I've combed through FCC filings for the latest news and driven to remote corners of California to test Starlink's cellular service.

I also cover cyber threats, from ransomware gangs to the emergence of AI-based malware. In 2024 and 2025, the FTC forced Avast to pay consumers $16.5 million for secretly harvesting and selling their personal information to third-party clients, as revealed in my joint investigation with Motherboard.

I also cover the PC graphics card market. Pandemic-era shortages led me to camp out in front of a Best Buy to get an RTX 3000. I'm now following how the AI-driven memory shortage is impacting the entire consumer electronics market. I'm always eager to learn more, so please jump in the comments with feedback and send me tips.

The Best Tech I've Had:

  • My first video game console: a Nintendo Famicom
  • I loved my Sega Saturn despite PlayStation's popularity.
  • The iPod Video I received as a gift in college
  • Xbox 360 FTW
  • The Galaxy Nexus was the first smartphone I was proud to own.
  • The PC desktop I built in 2013, which still works to this day.
