T-Mobile is set to expand its home broadband lineup with a new 5 Gig fiber internet plan that comes with a 10-year price guarantee. Priced at USD 90 per month with AutoPay, the plan is designed for households that need higher internet speeds across multiple connected devices.
The new offering will become available in select US locations starting November 3, 2026. Customers will also receive symmetrical upload and download speeds, unlimited data and a Wi-Fi router without additional monthly equipment charges.
One of the biggest attractions is the 10-year price guarantee. Unlike promotional broadband deals that increase after an introductory period, T-Mobile said customers signing up for this plan will have their regular monthly internet rate locked in for a decade.
However, the guarantee does not cover taxes, fees, voluntary equipment or speed upgrades, third-party services and certain other charges. Customers must also pay the applicable AutoPay price.

The 5 Gig package uses a full fiber-optic connection directly to customers' homes. This allows symmetrical speeds, meaning uploads can match download speeds.
The plan also includes unlimited data without usage caps, professional installation at no additional cost, a Wi-Fi router and a mesh Wi-Fi extender where needed. There is no annual contract, and customers do not need to subscribe to T-Mobile wireless services to access the plan's advertised pricing.
For a limited time, eligible customers can also receive two months free through bill credits and USD 300 in virtual prepaid cards.

With the new offering, T-Mobile is positioning its fiber service for households with demanding internet requirements, including online gaming, video streaming, remote work and smart home devices. Availability will depend on the company's fiber network coverage.
