If you received a recent e-mail or text about an improved wireless experience and/or received a SIM kit in the mail, the devices listed on your kit are eligible to access the T-Mobile network. Once you swap your SIM card(s), you’ll be able to take full advantage of T-Mobile’s network, with more coverage in more places.
Your Sprint account will remain the same, with the same price, plan, and billing experience but now you can access the T-Mobile network as your primary network. You also get immediate access to network-level scam protection with Scam ID and Scam Block, along with free Caller ID, all of which you can activate in T-Mobile’s free Scam Shield app. Learn more here. You can follow the instructions included in the kit to change out your SIM card(s).
