T-Mobile is quietly making its satellite service far more useful. What began as a way to send emergency texts when you’re out of cell range is slowly turning into a legitimate backup internet connection for everyday communication.

If you want to keep up with your group chats when you are out of traditional cell range, there is good news. T-Mobile’s T-Satellite service has expanded to support popular communication platforms like Discord, Signal, and LINE, according to The Mobile Report.

Satellite connectivity historically restricts you to plain text messages to keep data loads light. Supporting apps over a space-bound connection is a much greater challenge as modern applications consume vastly more bandwidth. T-Mobile has officially supported a small handful of navigation and messaging apps since launch, but this new batch came without any formal announcement.

All three, Discord, Signal, and LINE, are fully working over the satellite network, the outlet reports. In fact, Signal has reportedly been working since January. Discord apparently had no problem handling text chats, voice messages, and even image uploads across different servers, and LINE’s first tests also went off without a hitch.

You won’t get access to your entire app drawer just yet. T-Mobile has not updated its official page to reflect these additions either, so it’s unclear whether these apps are permanently greenlit or if they’re just going through an unannounced trial period.

Samsung owners have a handy built-in tool for checking which of their apps can talk to a satellite. You can find a custom list of compatible apps that are already installed on your phone under Settings > Connection > Satellite. If you don’t see the menu, check that your monthly plan really has satellite data. If you’re using another brand, you’ll have to test your apps manually.
