T-Mobile Fiber 5 Gig launches at $90 with 10-year price guarantee
The symmetrical 5Gbps tier needs no wireless subscription and includes unlimited data, a router and professional installation.
T-Mobile launched its T-Mobile Fiber 5 Gig plan on November 3, 2026, priced at $90 per month with AutoPay, excluding taxes and fees. The plan offers symmetrical 5Gbps speeds and does not require a wireless subscription.
T-Mobile says the base price for the 5 Gig tier is guaranteed for 10 years. The plan includes unlimited data, a router, professional installation and a mesh extender when needed, with no annual contract. New customers on the tier also receive two free months as bill credits and $300 in virtual prepaid cards, which can take up to 14 weeks to arrive.
Promotional pricing across the fiber lineup
The launch comes alongside limited-time promotional pricing: Fiber 300 at $35 per month, Fiber 1 Gig at $55 per month and Fiber 2 Gig at $70 per month. The promotions started on November 3 in select locations, and T-Mobile has not announced an end date.
Earlier this year, AT&T announced a $125 standalone 5Gbps rate and a $100 bundled price. When T-Mobile launched its broader fiber service, it offered five-year price guarantees and a limited 10-year Founders Club promotion; a shake-up earlier this year brought cheaper plans at the expense of those long-term protections.
