What you can do with the BYOD Check app

  • T-Mobile cannot and does not guarantee the functionality or performance of any handsets or devices that were not sold by T-Mobile or an authorized dealer of T-Mobile ("Non-T-Mobile Devices") for use on the T-Mobile network, or that do not have a software version sold or updated by T-Mobile (e.g., rooted devices).
  • T-Mobile is not able to test Non-T-Mobile Devices’ call quality, performance, data speed, feature compatibility, or other functionalities, so please be aware some experiences may vary greatly depending on the settings from your original carrier.
  • T-Mobile strongly recommends you contact the manufacturer of the Non-T-Mobile Device with any questions or problems regarding the functionality, operation, or performance of the device.
  • Check your warranty and contract with your current carrier to see what conditions apply to unlocking the device.
  • Coverage is not available in some areas.
