Carrier Unlocking the phone is a messy process for anyone, really. And that is because every phone has it own specifications and design. And that is exactly the case for T-Mobile as well. But let’s get to it, shall we?

So if your T-Mobile phone or tablet is showing you the message, “Sim Card not supported” when you have a simcard from other carrier, you’re in the right place! If you’re getting that message, it is because your phone is locked. And that’s not a bad sign or anything. All devices that are bought directly from T-mobile are locked, which means you cannot switch networks. 

There really are two ways to unlock your phone and here they are:

Way 1: Get your phone unlocked through the T-Mobile Unlocking Service for FREE

Unlocking can be a tedious and time-consuming though this method but this method is free. Unlocking can be different for both Android and iPhone. 

For Android, all support devices come with a pre-installed application called Device Unlock. It’s an application made by T-Mobile that allows you to request and apply a mobile device unlock directly from the device. The application is not on Play Store and if you don’t see it, try going to My apps & games > Installed in the Play Store. If it’s not there make sure, the application is not disabled or hidden on the device. And even if that’s not the case, it means you cannot unlock your phone with this way, go to the next one 🙂 (we will make sure you know how to unlock your phone one way or another).

Once you have the application, make sure you have the following

  1. A T-Mobile Account
  2. A supported device and make sure it’s the latest device software
  3. And there are other eligibility requirements which state that it should be in good standing.
  4. All payments should have paid
  5. There shouldn’t be a problem with the phone, meaning it’s not reported lost or stolen
  6. And basically that you’re following the agreements :). For more details on the requirements, please go here: It gives you specific requirements for the type of account you have.
