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.

Starlink will only support texting for now, but T-Mobile has said that the service will eventually expand to browsing and voice. The free beta provides users with high-speed internet connectivity in challenging-to-access areas such as rural locations, concerts, and even airplanes.
