If you’re a Verizon or AT&T customer, you can access T-Mobile’s Starlink service by activating an additional eSIM on your device. “Users will be assigned a T-Mobile number purely for provisioning the device to connect to the satellite constellation. The second eSIM will automatically activate whenever the user encounters a coverage gap,” explained a T-Mobile representative in an interview with Mobile World Live.

T-Mobile has also indicated that international roaming will be available through various partner carriers working with Starlink. The company mentioned a “growing alliance” among telecommunications operators dedicated to establishing reciprocal roaming arrangements. So far, this group includes carriers from countries such as Japan, Australia, New Zealand, Switzerland, Chile, Peru, Canada, and Ukraine.

How to Sign Up

To start using T-Mobile Starlink, you need to register for the beta trial, which is currently open to all users until July. “The beta is free and accessible to anyone, regardless of carrier,” T-Mobile stated.

The registration process involves filling out a brief form where you’ll provide your name, email, and phone number, along with permission for T-Mobile to reach out with marketing communications. “Entrance into the trial will be managed on a first-come, first-served basis, so we encourage early sign-ups,” T-Mobile advised.

T-Mobile is continuously accepting users to test the system and offer feedback before the official launch in July. Beta registration began in December. Preliminary reports from beta testers suggest that the service generally performs as promised—enabling text messaging in areas without cellular coverage—though some locations may still lack connectivity.

Pricing

Once the complimentary beta period concludes, T-Mobile customers can add the Starlink service to their existing plans for an additional monthly fee of $15 per line. Customers who enroll in the beta during February, or who have previously enrolled, will enjoy a $5 discount as early adopters when the service shifts from free beta to a paid option. This means early adopters will pay just $10 per month beginning in July 2025, according to T-Mobile.
