T-Mobile cannot guarantee the functionality of any handsets or devices which were not sold by T-Mobile or an authorized dealer of T-Mobile ("non-T-Mobile devices") for use on the T-Mobile network. Nor can we guarantee the functionality of any devices which 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. Device troubleshooting that is not related to the T-Mobile network (T-Mobile internet and picture messaging settings) is not provided. 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 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 continuing questions or problems with regard to the functionality.
