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.

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!

During the Super Bowl on Sunday, T-Mobile announced the public beta launch of its direct-to-cell program with Starlink. Customers can sign up, free of charge, until it moves out of beta in July. And you don't have to be a T-Mobile subscriber to try it out.
