Learn how to use your device on another carrier or wireless provider's network.  This may also be known as a SIM unlock, network unlock, or carrier unlock.

What's a Device Unlock

  • Device Unlock lets you use your device with another carrier, for things like international travel or selling your device.
  • Not all devices are compatible with every wireless provider; your device will need to support their network frequencies and technologies. 
  • This is different from Domestic or International roaming, where you use a T-Mobile SIM/eSIM to access a different wireless provider's network.

 

Unlock your device

  1. If you didn't get a notification about unlocking your device, make sure it's eligible to be unlocked.

    1. In a web browser, log into My T-Mobile and choose your line on the Accounts page. Not available in the T-Mobile app.
    2. Choose Check device unlock status to see if your device is locked or unlocked. If you have an unlocked iPhone, follow these steps to complete the process.
    3. Under the device image, you'll see if your device is eligible to be unlocked. See Device Unlock Policy for a list of eligibility requirements.
  2. Make sure you are connected to the T-Mobile network or Wi-Fi.

  3. Select your device type below and follow the steps:

    • Android

      1. Swipe up on your Home screen to open your Apps list and follow the steps for your manufacturer:

        • Samsung: Settings > Connections > More Connection Settings > Network Unlock

        • OnePlus: Settings > Wi-Fi & internet > SIM & network, then choose Advanced or Network Unlock

        • LG: Settings > Network & internet > Mobile networks > Network unlock > Continue

        • T-Mobile REVVLRY: Settings > Network & Internet > Mobile network > Advanced > Network Unlock

        • Older Android or other manufacturers: 
          • For Android 7 and newer, open the Device Unlock app. If you don't have this app, your device is either unlocked or uses one of the newer steps above.
          • For Android 6 and older, choose your device on the Devices page, then click the Security drop-down to find Mobile Device Unlock steps.

      2. Select Permanent Unlock and wait while the device completes the unlock.

      3. Restart the device.

    • Apple iPhone
