T-Mobile Cuts Fiber Prices for Fall, Adds Two Free Months on Top Tiers

T-Mobile is offering discounted rates on its fiber internet plans, with prices starting at $35 per month for the 300 Mbps tier when using AutoPay. The 1 Gig and 2 Gig plans are also reduced, and customers can get two months free on those higher tiers. The promotion coincides with the start of football season and peak TV premiere time.
T-Mobile’s fall promotion bundles two distinct incentives: reduced monthly rates across all three fiber tiers, and a two-month credit applied only to the 1 Gig and 2 Gig plans. The entry-level 300 Mbps plan drops to $35 with AutoPay, while the higher tiers see $10 monthly cuts. The offer runs alongside the company’s broader fiber rollout, which began as a pilot in 2021 and expanded commercially in 2025. The timing aligns with heavy home-internet usage periods, including football streaming and new TV premieres. Customers must note that after the free months, standard rates resume automatically.
This promotion could nudge price-sensitive households toward fiber upgrades during a peak entertainment season, potentially intensifying competition among ISPs. Consumers may benefit from lower entry costs, but the automatic renewal at higher rates could lead to bill shock if they forget the promo’s end date. The deal also highlights how streaming demand now drives broadband marketing, shaping choices for families balancing budgets and bandwidth needs.
