T-Mobile adds $90 5 Gbps fiber plan with 10-year price lock

T-Mobile’s new 5 Gbps fiber plan is $90 a month as of November 4, 2026, with a 10-year price guarantee if you pay on AutoPay.¹

The tier sits above the carrier’s existing home fiber lineup: 2 Gbps at $70 a month, 1 Gbps at $60, and 300 Mbps at $45. Every plan on that ladder, including the new top speed, is symmetrical on upload and download. Just over a year after T-Mobile launched home fiber in the United States through its Lumos acquisition—then reaching half a million customers at up to 2 Gbps—the 5 Gbps option is the new ceiling.¹

For $90 you get the 5 Gbps line, the included Fiber gateway, and a mesh Wi-Fi extender meant to stretch coverage beyond the gateway alone. New customers also get two months of free service through bill credits and a $300 virtual prepaid debit card.¹

The advertised rate is not the whole bill. AutoPay with T-Mobile is required for the $90 price. The 10-year lock leaves out taxes and fees, voluntary equipment or speed upgrades, select limited-time promotions, per-use charges, third-party services, and network management practices. The everyday ones most people will meet first are AutoPay as the gate to $90 and taxes and fees outside the lock.¹

Against other multi-gig fiber tags in the same report, GFiber lists 3 Gbps at $100 a month and 8 Gbps at $150. Where T-Mobile fiber does not reach, the company still sells unlimited 5G Home Internet starting at $50 a month.¹

Who this is for: addresses inside T-Mobile’s fiber footprint that want multi-gig symmetrical service, will run AutoPay, and can budget for the fees the lock does not cover. New sign-ups pick up the bill credits and debit card on top of the mesh extender.

This account of the launch rests on Tom’s Hardware’s reporting.

Our read: A decade-long $90 tag on 5 Gbps is a clearer number than most cable rate cards, and the mesh box is a real add-on rather than a coupon for something you might never use. The lock is only as clean as the carve-outs, though. Run the full monthly total with taxes and AutoPay, confirm the address is actually on the fiber map, and treat the new-customer credits as a short runway, not the permanent price.
