Unlock your mobile wireless device

Learn how to unlock your wireless mobile device for use on other carriers (formerly SIM Unlock).

 

We're committed to providing you with clear information about how to unlock your mobile wireless phones and tablets for use across different mobile carriers. Most mobile devices are programmed to prevent the device from operating with another wireless carriers network without first obtaining an unlock code.

 

If you purchased your device from T-Mobile or if you have a T-Mobile authorized device please follow the steps outlined below to determine your eligibility to receive an unlocking code for your device.

 

 

Device compatibility

It's important to understand that mobile carriers typically use different frequencies and technology to provide wireless network access. This means that not all phones and tablets are compatible between every mobile carrier – for more information about compatibility with T-Mobile’s network please check Bring Your Own Device. Even if your phone or tablet is compatible between carriers, some functionality of your device may not operate the same on a different mobile carrier’s network. Please carefully review your device functionality with any new carriers’ network to make sure that the services are operating as expected.

 

In order to obtain an unlock code for your mobile wireless phone or tablet you need to contact the mobile carrier or manufacturer who sold you the device. The original carrier or manufacturer can provide you with instructions and specific information on how to unlock the device for use with another mobile carrier.
