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.

T-Mobile used the recent Super Bowl to reveal that the Starlink beta will be available for any customer, regardless of which network they use.

Once you’ve signed up, your phone will be able to automatically connect to Starlink’s satellite network. This lets you send and receive iMessages and SMS texts when Wi-Fi and cellular service are unavailable. T-Mobile says that support for voice calls and mobile data will arrive at a later date.
