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 while roaming on any other network. Nor do we guarantee the functionality of any handsets or devices that do not have a software version that was sold or updated by T-Mobile (for example, rooted devices).

As a courtesy, we provide the T-Mobile Internet and picture messaging (MMS) settings for some Non-T-Mobile Devices. However, device troubleshooting that is not related to the T-Mobile network (T-Mobile Internet and picture messaging settings) is not provided for such Non-T-Mobile Devices. T-Mobile does not provide troubleshooting on Non-T-Mobile Devices for any issues not related to the T-Mobile network.

T-Mobile cannot guarantee the effectiveness of these settings, nor their placement in the device and therefore does not assume any liability for the lack of effectiveness of these settings for non-T-Mobile devices.

We strongly recommend that our customers contact the manufacturers of their Non-T-Mobile Devices with any questions or problems regarding the functionality, operation, or performance of their Non-T-Mobile Devices.
