Most mobile devices are programmed to prevent the device from operating with other wireless carriers’ networks without first being unlocked. We're committed to providing you with clear information about unlocking your mobile device. 

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 for device unlocking. In order to unlock a mobile device that is not sold or authorized by T-Mobile, you need to contact the mobile carrier or manufacturer who sold you the device.

Once a device becomes eligible for unlocking (eligibility criteria are described below), T-Mobile will automatically and remotely unlock the device within two business days if device supports remote unlock. You can check your device’s unlock status in your my T-Mobile account.

Some devices cannot be remotely unlocked by T-Mobile. In these cases, T-Mobile will send a notification to the device within two business days of it becoming eligible, with next steps to complete the unlock process.

We unlock mobile devices that meet the following eligibility criteria free of charge.

Device eligibility is determined as follows:
