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, tablets, and mobile Internet devices for use across different mobile carriers. Most mobile devices are programmed to prevent the device from operating with another wireless carrier's network without first obtaining an unlock code. Keep in mind, T-Mobile cannot unlock a non-T-Mobile device.
Mobile carriers typically use different frequencies and technology to provide wireless network access. So, not all phones, tablets, and mobile Internet devices are compatible between every mobile carrier. Even if your phone, tablet, or mobile Internet device is compatible with carriers, your device may not operate the same on a different mobile carrier’s network. Please review your device functionality with any new carrier's network to make sure that the services are operating as expected. For more information about T-Mobile’s network compatibility requirements, see Bring Your Own Device.
To obtain an unlock code for your mobile wireless phones, tablets, or mobile Internet device, 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. If you purchased your device from T-Mobile, or if you have a T-Mobile authorized device, follow the steps outlined below to see if you're eligible to receive an unlock code for your device.
We provide mobile device unlock codes free within two business days (or provide further information about timing) for eligible devices.
