Beginning November 3, 2026, T-Mobile Fiber will offer a 5 Gig internet plan at $90 per month with AutoPay plus taxes and fees, backed by a 10-year price guarantee. The company is also rolling out expanded Fiber 300, Fiber 1 Gig, and Fiber 2 Gig pricing, including limited-time offers in select locations.
Why it matters
The price guarantee and bundled bill credits and prepaid card offers give U.S. households a fixed-cost option for ultra-high-speed home internet. The move adds pricing pressure on competing broadband providers across the country.
The Fiber 5 Gig plan is priced at $90 per month with AutoPay, while the limited-time Fiber 300 and Fiber 1 Gig tiers drop to $35 and $55 respectively. Virtual prepaid cards of $100 to $300 are tied to specific tiers, and the announcement does not say how many subscribers will qualify for them.

The Tech Race
The 5 Gig tier positions T-Mobile against cable and fiber rivals in the high-speed home broadband market. The extraction does not name a specific competitor or prior price benchmark to anchor this comparison further.
Households that subscribe to the Fiber 5 Gig plan will pay $90 per month with AutoPay for a 10-year price guarantee, with no promotional discount on the base rate. Limited-time offers on Fiber 300 and Fiber 1 Gig require redemption within 14 weeks to receive bill credits and prepaid cards.
