Mobile Device Unlock App For Android Phones (MetroPCS USA) – Debugging & Troubleshooting

A locked android phone on MetroPCS can’t be unlocked with just a code but requires an Android App that allows you to request and apply a mobile device unlock directly from the locked device.

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.

It’s very important to order the unlock service of your Mobile Phone using the correct service.
