Mobile Device Unlock App (Android)

Device Unlock is an Android app that allows you to request and apply a mobile device unlock directly from the device. This allows you to automatically apply Mobile Device Unlock to the device without using a manual code. When your phone is locked with “Mobile Device Unlock” it’s totally useless to order an unlock code.

Only supported devices (see below) may download the app or have it pre-installed. Supported devices may download the app from: Google Play.
