Using Our T-Mobile Unlock Service we will Network Unlock your T-Mobile Device using the Official T-Mobile Device Unlock APP.

Once we have e-mailed you that our work is completed on our end, you need to open the T-Mobile Device unlock APP and click on Permanent Unlock. Then Restart your phone and the device will be permanently network unlocked.


Detailed Explanation:

1) Calling T-Mobile and paying them to unlock it.   If you have met the terms and conditions of T-Mobile service agreement then you can contact T-Mobile if you need a temporary unlock (when travelling) or a permanent unlock ( when switching carriers permanently).   First you can check the status of the phone to make sure it is a T-Mobile device and it's not reported stolen or has money owing on the account.  You can check this for free here:

If your account is in good standing and you want to proceed to unlock it through T-Mobile then simply call them for further instructions.  T-Mobile customer service number is 1 505-998-3793

2) Using a 3rd party service to unlock it using the T-Mobile APP.  This method is the same as the previous method. You will use the official T-Mobile device unlock APP to unlock the phone but you won't call or pay T-Mobile.  This is especially useful if T-Mobile wants to charge you more money than us or they refuse to unlock it because money is owed to them. Then you can use this service.  It should be noted: If your phone is blacklisted by T-Mobile then we also have a service to remove this Blacklist from their database.  Remember, if you don't remove this blacklist, then even if the phone is network unlocked, no other carrier in North America will allow it on their network.

3) Using our T-Mobile unlock APP bypass sotware: This method is usually the cheapest and FASTEST option and  it works great.  Basically you need to download our white labelled software.  When you download the software and run it on your computer (with WINDOWS) you will need to enter in a username and password.  We will provide you with this username and password once you have paid for the service.   Once the software is running you would simply need to connect your phone with the USB cable that came with the phone to one of the available USB ports on your Windows Computer.  After your phone has been detected, simply press the unlock button on the software and the software will do all the work the unlock your phone.  Once your phone has been unlocked then you can disconnect it from the computer and use it on any compatible network worldwide.  Please note: If the phone is blacklisted it won't work in North America unless you remove the blacklist (we have a service for that too!)   Refer to the bottom of this page for more detailed steps on how to download, open and use the software. No Rooting, No Finger Print Required. Simple plug and play solution to unlock a T-Mobile Android phone . This is a  Permanent Unlocking Solution.

Update: T-Mobile has replaced the unlock APP on some newer phones with a unlock option under the settings called: Network Unlock. It works the same way the Unlock APP would and you can still use our service called T-Mobile Official Unlock APP service for these phones even though technically they don't have the APP as long as you get the "Not Eligible for Unlock" message when your click the Permanent Unlock option. The T-Mobile Galaxy S10 and some newer models have this under the settings as shown in the picture below:

How to unlock your device from T-Mobile with the Device Unlock App

Back in 2014, T-Mobile changed the way certain Android smartphones could be unlocked from their network. By pre-installing a Device Unlock App on the phone, T-Mobile customers can now request and apply a mobile device unlock directly from the device.


This is the only way to unlock a Samsung, LG, Alcatel, HTC, Huawei, Kyocera, Motorola, Sony Xperia or ZTE phone from the T-Mobile network with the Device Unlock App. The latest devices don't have the APP anymore but under the phone settings there is an option for network unlock . This works the same way as the App would.

Before proceeding to order the unlock service from us, just make sure to check that the APP is working correctly.  When using the APP it should initially say "Not Eligible for Unlock", if you are getting the messages "Communication Error" or "Server not responding" Please try again later or Error code = 255 " then do not order until you find a way for your phone to communicate properly with the server. 

We have some tips to fix these errors that you can find under troubleshooting steps found near the bottom of this page.

Don't install any device unlock APPs from the Google Play store!

The official T-Mobile Device Unlock APP is not in the Google Play store although there is a lot of look-a-like [fake] apps to be found when searching for 'DEVICE UNLOCK APP'.

The T-Mobile APP comes in the Application folder that is already pre-installed on your phone.   If you can't find this APP then it may be hidden, you can try  searching for it in your app settings.

What if the APP is not found on my phone?

If the APP is still not there, then there is two possible reasons for that.  Either your phone is already unlocked [the APP uninstalls itself after a successful permanent unlock] or the second possible reason for the APP to not be there is that your phone was made before 2015 when T-Mobile was still using unlock codes.  If that is the case, then you need to order an unlock code instead [Message us and we will provide a code instead].  If this is the case then before ordering an unlock code, simply insert a SIM card from a different carrier and make sure the phone asks automatically for a network unlock code.

What if my T-Mobile phone is Blocked for unpaid Bills, will the service work?

If your phone is blocked or blacklisted because it is reported lost or stolen or has unpaid bills then the phone may not work even after successfully unlocking it since carriers in North America are required to refuse service for phones reported as Blacklisted.
