T-Mobile has launched Text to 911 via Starlink-backed satellite, free for users with compatible devices from any carrier, including Verizon and AT&T.

For full access, T-Satellite features cost $10 per month and are separate from the free Text to 911 service.

The rollout reflects T-Mobile’s broader strategy to extend satellite network access beyond its own customers to improve emergency reach where terrestrial coverage is weak.

Compatible devices include iPhone 13 or newer and select Android phones, with automatic setup when terrestrial signals are unavailable.

Non-T-Mobile customers must have an unlocked phone with an eSIM to enroll.

The service uses Starlink satellites to cover about 500,000 square miles in the U.S. without cell towers and requires a clear sky view.

Text to 911 complements other satellite emergency options from Apple and Google by offering a user-friendly backup that doesn’t require manual satellite pointing.

Enrollment is via T-Mobile’s signup page, and the core free feature carries no fee unless additional T-Satellite features are activated.

Once enrolled, compatible phones automatically connect to T-Mobile’s emergency texting network in areas lacking cellular service.

Eligible devices for free texting include iPhone 13 and newer (with some model caveats), Pixel 9 and up (excluding 9A), Galaxy S21 and newer, and newer Motorola models.

The system relays texts to emergency services via Starlink when there is no cellular or Wi‑Fi coverage, enabling text-to-911 rather than voice calls.

Text to 911 lets users connect with emergency services even when voice calls aren’t possible, with free access for compatible devices and sign-up required for those outside certain plans.
