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. Log into your T-Mobile Account and choose your line on the Accounts page.
    2. Choose Check device unlock status to check if your device is locked or unlocked.
    3. Under the device image, check if your device is eligible to be unlocked. Review 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 and follow the steps:
