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.

No cell service? No problem. You can now text from anywhere thanks to T-Mobile’s Starlink, a new program that aims to bring connectivity to even the most remote places. The beta service is free and open until July for both T-Mobile customers and AT&T and Verizon users.

The beta phase will run until July. Afterward, you can decide if you want to pay for the service.
