Device Unlock is an Android app that allows you to request and apply a T-Mobile mobile device unlock directly from the device. The features of this app include the ability to remotely request Mobile Device Unlock without having to contact Customer Care and automatically apply the Mobile Device Unlock to the device without the use of a manual code.
WARNING: Make sure your cell phone is 100% CLEAN (not reported as "Lost" or "Stolen") using this Link: http://www.t-mobile.com/verifyIMEI.aspx [nofollow this link pls!] before placing your order - as you might end up having to pay for a "Cleaning Service" on the top of the unlock to be able to use the phone in the USA. And we're not offering cleaning service! Blacklisted = NOT SUPPORTED = NO REFUND!
Also before order, please read this post: "Mobile Device Unlock App (Android) – Troubleshooting". It details properly the whole entire process and how to apply the unlock. Order only if your phone shows: "Unlock Failed: This mobile wireless device is not eligible for unlock. For Device Unlock eligibility details, please go online or contact Customer Care."
Once the unlock request is processed, you'll need to:
If successful, restart the device to apply the settings.
All you need is an Android device that supports the Mobile Device Unlock app:
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. Before place your order try to use the application and make sure it show "Not Eligible for Unlock", if you see "Communication Error" or "Server not responding. please try again later." do not order until you find a way for your phone to communicate properly with server. 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.
