T-Mobile is best known for its cell phone and 5G home internet plans, but the provider has started to venture beyond wireless internet services. T-Mobile Fiber is the carrier’s newest offering, and it aims to bring high-speed fiber internet service directly to the homes of millions of customers around the U.S.

T-Mobile’s four fiber internet plans cover the expected bases for fiber internet service. You’ll get equal upload and download speeds on all four plans, and its pricing is competitive with fiber internet service providers (ISP) like AT&T Fiber and Google Fiber.
These similarities also apply to the internet fine print: T-Mobile Fiber doesn’t offer contracts and has its 5-year price guarantee, so you won’t have to deal with expensive early termination fees or the annual price increases you’d typically see from cable ISPs.
Where is T-Mobile Fiber internet available?
T-Mobile Fiber is a wet-behind-the-ears newcomer to the ISP market, and this becomes wildly apparent when you look at the provider’s availability. T-Mobile Fiber is available in the following states:
- Alabama*
- California
- Colorado
- Florida
- Georgia*
- Illinois
- Indiana*
- Ohio*
- Michigan
- Minnesota
- New York
- North Carolina*
- Kentucky*
- South Carolina*
- Virginia*
- Wisconsin
*Added as part of Lumos acquisition.
On top of that, T-Mobile’s availability remains a work in progress since T-Mobile (like all fiber ISPs) must physically install fiber networks on a city-by-city basis. For instance, T-Mobile Fiber is available in a whopping three cities across Michigan, Illinois, and Wisconsin.
That said, T-Mobile made a huge move to nearly double its footprint by acquiring Atlantic Coast-based fiber ISP Lumos in April 2025. According to Lumos, they’ll gradually roll existing customers over to T-Mobile Fiber throughout 2025, and if your town previously had Lumos coverage, you’ll be able to get T-Mobile Fiber.
Currently, you’ll have the best odds of getting T-Mobile Fiber service directly from T-Mobile if you live in the northern Denver suburbs, Florida, or New York City. T-Mobile Fiber also takes internet preorders to prepare customers in eligible areas slated to get fiber internet.
Why is T-Mobile getting into fiber internet?
If it seems weird that a cell phone carrier offers you wired home internet service, rest assured that you’re not alone in thinking this! One of the big recent internet trends has been ISPs launching cell phone services, but this trend rarely goes in the opposite direction.
That said, T-Mobile’s 5G Home Internet service has been a hit for the carrier. The service has been one of the top performers in CableTV.com’s annual Internet Customer Satisfaction Survey and landed our Editor’s Choice Award for best value ISP.
T-Mobile has described T-Mobile Fiber as a service that could live alongside T-Mobile 5G Home Internet as a higher-end internet offering, and they’ve backed up this talk with their wallet. Back in 2024, T-Mobile announced it would spend $1.45 billion to acquire fiber ISP Lumos Networks and closed on the sale in April 2025—the carrier wants to get fiber coverage in 3.5 million homes by 2028.

Is T-Mobile Fiber home internet worth it?
T-Mobile Fiber’s minuscule network and relative inexperience make it tricky to compare it to established competitors like AT&T Fiber and Verizon Fios. By ISP standards, T-Mobile Fiber’s still getting off the ground, and its barebones availability means it’s a fraction of the size of its competitors.
But broadly speaking, T-Mobile Fiber offers many of the things we like to see from fiber ISPs: flat-rate billing, symmetric speeds, and pricing that won’t break your wallet. T-Mobile’s Lumos acquisition also shows that the carrier is willing to spend to become a serious player in the fiber ISP space.
If your neighborhood is fortunate enough to get T-Mobile Fiber coverage and you’re sick of dealing with your cable ISP, it’s worth exploring T-Mobile Fiber as a step up in your internet service.
