In a surprising and generous move, Apple is rolling out a free satellite messaging feature for iPhone 13 users through the latest iOS 18.5 update. This feature doesn’t require new hardware and is being enabled via a partnership with T-Mobile and Starlink.
The new service, called T-Satellite, brings emergency satellite-based text messaging to iPhone 13 and later models. Previously, satellite connectivity was only available on iPhone 14 and 15 through Apple’s Globalstar system. But now, iPhone 13 users get access too, without paying extra or upgrading their phone.
The service will officially go live on July 23, but T-Mobile has already activated it early for customers affected by the devastating floods in Texas. Those users can now send emergency texts to 911, receive wireless alerts, and stay connected even when the mobile network is down.
Unlike Apple’s SOS feature, this system uses carrier-supported satellite messaging, and the network behind it is SpaceX’s Starlink. T-Mobile confirmed that 657 Starlink satellites will be dedicated solely to the T-Satellite service, aiming to cover the 500,000 square miles of the U.S. that lack mobile signals.
Users don’t need to point their phone to the sky. The system works even when the phone is in your pocket—making it extremely user-friendly during emergencies or in remote areas.
The service is free for T-Mobile Experience Beyond subscribers, while users on AT&T or Verizon can access it for $10 per month. This price is lower than the originally expected $15–$20, making the offer more attractive to non-T-Mobile users as well.
Currently, the service supports basic SMS texting, but multimedia messaging, images, and short audio clips are expected to roll out soon. Over 1.8 million users have already joined the beta program, including “tens of thousands” from other networks.
T-Mobile is positioning this as a major leap toward eliminating dead zones in mobile communication. The satellite connectivity also supports text-to-911, and the company says the feature will later be available to all compatible mobile users, regardless of carrier.
This development is a win for iPhone 13 users who were previously left out of satellite features. It also signals the growing importance of universal connectivity, especially during emergencies.
For now, iPhone 13 users can enjoy this surprise “gift” from Apple and T-Mobile, simply by updating their software—no new phone is needed, just better, smarter coverage.
