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.
