What is the Device Unlock App?

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.

How to unlock your phone with the Device Unlock App?

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:

Process your unlock request through doctorSIM. Select the make of the phone, then the T-Mobile or MetroPCS network, and finally our Device Unlock App Service. DO NOT choose any other service as this is the ONLY method that will unlock your smartphone with the Device Unlock App pre-installed by T-Mobile or MetroPCS.
Once processed, you will shortly receive an e-mail informing you that the phone's IMEI number has been registered as unlocked on the T-Mobile or MetroPCS server.
Insert your new SIM card.
Open the Device Unlock App and select the "Permanent Unlock" option to complete the process.
The following message will appear on screen: "Unlock Approved: Mobile device is permanently unlocked".
Press "Restart Now" to begin using your phone on any other GSM network in the world.

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.
