Introduced in 2014, Device Unlock is an Android app that allows you to request and apply a mobile device unlock directly from the device. This is the only method that works for Samsung, LG, Alcatel, HTC, Huawei, Kyocera, Motorola, Sony Xperia and ZTE devices that do not prompt for the unlock code.
Check to make sure your phone can be unlocked using the Device Unlock App as not all phones can be unlocked using this method. Open the Applications icon on the smartphone to see if T-Mobile or MetroPCS have pre-installed the Device Unlock App on the device.
If so, follow the simple instructions below:
NOTE: If you do not have the app on your phone, you can still unlock the device the traditional way selecting either our Standard or Premium Service. However, the phone must prompt for the unlock code. If it does not, unfortunately, your phone cannot be unlocked via IMEI.
