T-Mobile has shared a list of devices that are compatible with the Starlink beta for free satellite messages. Check out if yours is included!

T-Mobile’s Starlink-powered direct-to-cell satellite messaging service is now open for anyone in the US to try for free — including people who aren’t T-Mobile customers. The service will be limited to text messaging at first but the company hopes to have some apps and even limited multimedia support ready by the time it goes live this summer.

Want to try the new Starlink satellite connection on your phone? Sign up to the T-Mobile beta and you can, for free, until July—even if you’re with another carrier.
