Metro by T-Mobile Phone Unlock Policy

Unlocking your mobile wireless device

When purchasing a mobile device from a wireless carrier, the device is generally programmed to operate only on that carrier’s network. To use the mobile device on with service from another carrier, it must first be unlocked.

We're committed to providing you with clear information about unlocking your mobile device.  

If you purchased your device from Metro by T-Mobile or if you have a Metro by T-Mobile authorized device, please follow the steps outlined below to determine your eligibility for device unlocking and to unlock the device. To unlock a mobile wireless device which was not sold or authorized by Metro by T-Mobile, you will need to contact the mobile carrier, manufacturer, or retailer that sold you the device.


Metro by T-Mobile’s approach to device unlocking

Once a device becomes eligible for unlocking (eligibility requirements are described below), it will automatically be remotely unlocked within two business days by Metro by T-Mobile.

Some devices cannot be remotely unlocked by Metro by T-Mobile. In these cases, Metro by T-Mobile will send a notification to the device within two business days of it becoming eligible. The notification will explain the next steps to take to complete the unlock process.

If you received a notification that your device is eligible to be unlocked, and you need instructions for completing the unlocking process, click here.
