Apple Enables T-Mobile Customers to Send Text Messages via Satellite with iOS 18.3 Update

The latest update Apple rolled out for the iPhone allows T-Mobile customers to send text messages even in locations where they have no coverage. iOS 18.3 adds support for SpaceX and T-Mobile’s direct-to-cell satellite service, which is currently being trialed after the companies opened signups for beta testing in December.

Partnership with SpaceX

As Bloomberg notes, the service used to be only compatible with certain Android phones, including Samsung models like the Z Fold and S24 along with select devices running Android 15. Meanwhile, Apple already has a partnership with Globalstar that provides users with texting capabilities when they’re out of coverage.

Beta Trial Experience

Users who’ve signed up to participate in the fledgling service’s beta trials have reportedly started receiving texts. "You can now stay connected with texting via satellite from virtually anywhere," the message reads, according to Bloomberg. And for iPhone users, it asks them to "update to iOS 18.3" to "start experiencing coverage beyond." Once they do download the update, they’ll see a toggle in their cellular data settings to activate the capability.

Current Limitations and Future Plans

At the moment, the direct-to-cell service only offers text messaging. If a beta tester finds themselves in rural areas and other locations that typically don’t have coverage, they’ll be able to use Starlink’s satellite network to send a text. In the future, the plan is to add voice and data connectivity to give people more options in far-flung locations.
