MetroPCS USA Android Official app unlock

It's mandatory with "MetroPCS Device Unlock App" Service to check BEFORE placing your order that your phone shows "Not Eligible for Unlock"
If instead you have the error "Server not responding" this mean your phone is not even able to communicate with MetroPCS Server (Communication Error)
You need to fix this problem before ordering since we do not accept complaint / refund request about this specific error.

Once the unlock request is processed, customer needs to:
    Make sure you have an active data connection via 3G/4G/LTE or Wi-Fi.
    From the Application list, tap Device Unlock. (Note: The application may be located in the MetroPCS folder.)
    Tap Continue.
    Choose the Permanent Unlock type:
    If successful, restart the device to apply the settings.
Note: If you do not restart the device, you will have a persistent alert in the notification tray.
WARNING:  It is very important to mention that the customer has to have data when attempting to perform the unlock, either 3G, 4G or wi-fi but data on the phone. If there is no data the unlock will be unsuccessful, once a device has been whitelisted we will not be responsible for unsuccessful unlocks. If customer has changed the original software or IMEI we will not be responsible for the app not to work (Do not install custom firmware like Avatar or Cyanogen  before unlock your phone). If customer cannot find the app on its phone he can easily go to applications and make it visible but a Hard Reset will always bring the app back to the phone.

We only refund for "NOT ELIGIBLE FOR UNLOCK" issue, we will not refund any complaint about "Communication Error" or "Server not responding. please try again later.". It is mandatory to check before ordering if your phone have "Server not responding. please try again later." issue. If the answer is yes then you can try to fix this error by performing a hard reset on your phone, or upgrading his firmware. Again make sure your phone can communicate with "Device Unlock App" server BEFORE place your order.
