Device Unlock

Device Unlock is an app that you can use to request for your Android device to be unlocked. However, It's important to mention that the app is only compatible with Samsung Avant devices, so you could get different errors if you use other types of devices.

To use the app you need a T-Mobile account, a compatible Android device with the latest software version and Internet access (preferably through a WiFi network). If you meet these three requirements, then you can use the app.

Device Unlock is a simple and easy-to-use app. Just follow the steps that appear on the screen, and in a few seconds, your Android device will be unlocked. Do keep in mind that you need to meet all the requirements listed above.
