Quick answer

T-Mobile has expanded its T-Satellite service to support Discord*, Signal, and LINE for messaging and media sharing outside cellular network coverage.

U.S. carrier T-Mobile has expanded the functionality of its T-Satellite service by adding support for three popular messaging apps: Discord*, Signal, and LINE. Users can now continue group chats, send voice messages, and even upload images while in areas without cellular network coverage. The update was discovered without an official announcement, raising questions about its status—whether it is a permanent solution or part of a limited testing phase.

Previously, satellite connectivity was limited to basic text messages due to low bandwidth. Supporting full-fledged apps like Discord* or Signal requires significantly more resources, as modern messengers actively use multimedia content. According to The Mobile Report, Signal has been working via satellite since January, and Discord* handles text chats, voice messages, and image uploads seamlessly, even in large servers.

T-Mobile has not yet updated the official information about the service, so it remains unclear whether these apps will be available permanently. Samsung smartphone users can check the list of compatible apps in their device settings: Settings → Connections → Satellite. Users of other brands will need to test support manually. The feature requires a satellite plan as part of a monthly subscription.

**** The Discord messenger is banned in the Russian Federation.
