T-Mobile Fiber has added a 5 gig plan to its Home Internet service, giving heavy users a faster option for their data needs.

T-Mobile may be best known for its wireless service, but the company also has a fiber internet service in select markets. The company is adding a 5 gig plan to give heavy users a faster experience.

According to CNET, the plan is available as of November 3, 2026 and will cost $90 per month with AutoPay. The new plan includes a 10-year price guarantee and includes unlimited data, as well as equal upload and download speeds.

To sweeten the deal, T-Mobile is offering a limited-time promotion where users can get the first two months free via bill credits, along with $300 in virtual prepaid cards.

T-Mobile is clearly trying to attract more users to its fiber service, and the 5 gig plan appears to be a good way to do it.
