T-Mobile Price Promotions (including Price Guarantee, Price Lock, & Un-contract Promise): Frequently Asked Questions

  • 5-Year Price Guarantee

    As of April 23, 2025, customers activating a new account on an Experience plan, or existing customers switching their account to an Experience plan, will receive our 5-Year Price Guarantee (“5-Year Guarantee”). Under this 5-Year Guarantee, a customer’s monthly price for talk, text, and T-Mobile 5G data is guaranteed for 5 years from account activation (or from plan enrollment for accounts that activated before April 23, 2025). Later adding voice lines to an already-existing Experience plan account, or later changing from one Experience plan to another does not start a new 5-year period. The 5-Year Guarantee is also available for non-smartphone lines (like tablets or watches) if they are attached to an account with an Experience voice plan, but adding these lines does not extend or restart the duration of the 5-Year Guarantee. The 5-Year Guarantee excludes taxes/fees, per-use charges, plan add-ons, third-party services (such as satellite connectivity), and network management practices.

     

    Price Lock

    Other customers activating or switching to an eligible rate plan starting January 18, 2024 and ending April 22, 2025 get our Price Lock guarantee (“Last Month Price Lock”), where the regular monthly rate plan price stays the same, but if we do ever make a price change and you decide to leave, just let us know within 60 days and we’ll cover the cost of your final month’s recurring service charges. Taxes/fees, select limited-time promotions, per-use charges, third-party services (such as satellite connectivity), discounts, and device and network management practices are excluded. 

     

    For accounts activated between April 28, 2022, and January 17, 2024, customers who signed up for qualifying mobile wireless plans received our original Price Lock Guarantee (“Original Price Lock”). Under that promotion, new accounts with qualifying service could keep their regular monthly rate plan price for unlimited talk, text, and data on our network, excluding taxes/fees, select limited-time promotions, per-use charges, third-party services (such as satellite connectivity), discounts, and network management practices. 

     

    Qualifying mobile wireless accounts activated before April 28, 2022, received our Un-contract Promise. The Un-contract Promise is our commitment that only you can change what you pay for your monthly talk, text, and data rate plan. We will pay your final month’s recurring service charge if we raise prices, and you choose to leave. Just let us know within 60 days.

     

    For more information, please contact us by dialing  611 from your T-Mobile phone or calling 1-800-937-8997.

  • 5-Year Price Guarantee 
    As of April 23, 2025, customers activating a new line on any T-Mobile Fiber plan will receive our 5-Year Price Guarantee (“Fiber 5-Year Guarantee”). Under this Fiber 5-Year Guarantee, a customer’s monthly price for internet data is guaranteed for 5 years from account activation (or from plan enrollment for accounts that activated before April 23, 2025). Later adding or changing plans to an already-existing account does not start a new 5-year period. The 5-Year Guarantee excludes taxes/fees, limited-time promotions (such as free lines), discounts (such as AutoPay), per-use charges, plan add-ons, third-party services (such as streaming benefits), and network management practices.

     

    Eligible customers, invited to join the T-Mobile Founders’ Club in select locations, will receive our 10-Year Price Guarantee (“Fiber 10-Year Guarantee”). The Fiber 10-Year Guarantee will offer the same benefit as the Fiber 5-Year Guarantee for a longer period.
