Device Unlock enables T-Mobile equipment to use a non-T-Mobile SIM card to connect to a different international or domestic network. Most devices sold by T-Mobile come locked to our network in order to prevent theft and fraud. In most cases, once you’ve met our criteria that qualifies you for an unlock your device will be remotely unlocked. Otherwise you'll receive a text letting you know your device is qualified with next steps to complete the process.  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 a different wireless provider's SIM/eSIM and network. Don't worry about it f you only plan to use the T-Mobile network.

  • 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.
  • For more information on T-Mobile's approach to device unlocking, see Device Unlock Policy.
