Unlock Your T-Mobile Network Experience

Don't wait, update your SIM card to take full advantage of our best network.

What To Expect

We’re committed to delivering Sprint customers our best experience yet. To see what this commitment means for you, view our Sprint Customer Promise.


Eligible Sprint customers can now take advantage of the full T-Mobile network with a simple SIM swap. Your Sprint account remains the same, with the same price, plan and billing experience, but now you’ll access the T-Mobile network as your primary network.

With the T-Mobile Network Experience:

  • Your device will show the T-Mobile network and you’ll get the full T-Mobile Network experience.
  • You’ll get access to T-Mobile’s free Scam Shield app, with exciting services like free Scam ID, Scam Block, and free Caller ID!
  • You'll keep your current plan and billing through Sprint.

Visit a Retail store or Chat/call Care at 888-211-4727 (or dial *2) and we can evaluate your account.

  • If there’s a certain date/time you want to visit a store, you can set up an appointment via the store locator for shorter wait times.
    • Enter your location and under the filter choose Serves Sprint customers.
    • Choose your store then click on Appointment.

We’ll check the following eligibility requirements:

  • You have a qualifying plan.
  • You have a qualifying device.
  • You’re in a qualifying T-Mobile coverage area.
