Get peace of mind with T-Mobile’s Price Lock guarantee for billing accounts activated after April 28, 2022. Price Lock guarantees that new accounts with qualifying plans can keep the same regular monthly rate plan price for their current unlimited talk, text, and data on our network.

What is Price Lock

Price Lock is an assurance that T-Mobile won’t raise the rate plan price for qualifying plans on T-Mobile billing accounts activated after April 28, 2022. This assurance is automatically activated for talk, text, and data on Essentials, Magenta, MAX, 55+, Military, First Responder, and Business Unlimited plans. The rate plan price guaranteed by Price Lock will be the current published price when the plan is added to a line. Price Lock excludes taxes and fees, limited-time promotions, per-use charges, third-party services, and network management practices. This Price Lock protection applies as long as the qualified plan is not removed or altered by the primary account holder.

Qualifying Plans

The following plans qualify for Price Lock on accounts in good standing opened after April 28, 2022.

If these plans don't fit your needs, find one that does on our T-Mobile Plans Features page.

Does Price Lock cover promotions or other services?
The price you pay for unlimited talk, text, and data on your qualifying smartphone or tablet plan won’t change, but other aspects of your service are subject to change – such as:
  • Charges outside of T-Mobile control like taxes & fees and third-party charges.
  • Promotional offers, bill credits, and additional future lines may not be included; check out your rate plan promotion for details. It does not apply to add-on features, non-recurring costs, or additional services. Network management practices will continue to be optimized to give all of our customers the best experience.
If I try another plan in the future, can I revert to my prior plan to re-establish Price Lock?
No. Price Lock applies to the published rate plan price on the date of activation for each line, not the original price paid when the account was opened. The Price Lock Guarantee will continue to apply to additional lines or qualifying plan changes until T-Mobile announces any change to our pricing promise.
Does Price Lock cover taxes and fees?
Taxes and fees are outside of T-Mobile’s control and are not covered by Price Lock.
Can I still get Price Lock if my billing account was activated before April 28, 2022?
No. A similar price assurance exists called Un-Contract for billing accounts activated with eligible plans on or before April 27, 2022. For customers who activated an eligible rate plan before April 27, 2022, the Un-Contract promise is our commitment that only you can change what you pay, and we mean it! To show just how serious we are, we have committed to pay your final month’s recurring service charge if we were to raise prices and you choose to leave. Just let us know within 60 days.
