T-Mobile Starlink is obviously available to T-Mobile customers, but the carrier said that Verizon and AT&T customers can also use it on their existing phones without switching entirely to T-Mobile. Verizon and AT&T customers will need an unlocked phone with eSIM technology, which lets users activate a cellular plan without a physical SIM card.

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.

Providing connectivity in areas where it’s never been available before will be incredibly useful for a lot of people.
