Apple has quietly collaborated with SpaceX and T-Mobile U.S. to integrate Starlink network capabilities into its latest iPhone software update. This move introduces an alternative to Apple’s existing satellite communication service provided by Globalstar.
According to Bloomberg’s Mark Gurman, the companies have been testing this integration with Starlink, a service from Elon Musk’s SpaceX, on iPhones. With the release of iOS 18.3 on Monday, this support became available, although Apple did not highlight this in the update notes.
Previously, T-Mobile had only identified Starlink compatibility with certain Samsung models, like the Z Fold and S24. Apple’s service through Globalstar allows texting and emergency communications when out of cellular range, but now, Starlink offers an additional option.
T-Mobile Starlink beta
According to the report, T-Mobile has started inviting users to participate in a beta test of the Starlink service, with some iPhone users receiving a message that reads, “You’re in the T-Mobile Starlink beta. You can now stay connected with texting via satellite from virtually anywhere. To start experiencing coverage beyond, please update to iOS 18.3.” Participants can manage this new satellite feature through a toggle in their iPhone’s cellular data settings, the report noted.
Upon confirming the service availability, Elon Musk commented on X (formerly Twitter), stating that the current technology supports images, music, and podcasts, with future updates promising video support.
T-Mobile has stated that the beta test is launching with select optimized smartphones and will later support most modern devices, while some Android 15 users have also been invited to join the beta program, the report added.
How It Operates:
- When a T-Mobile iPhone lacks cellular connectivity, it attempts to connect to SpaceX’s satellites if enrolled in the Starlink program. Users can also use the satellite menu to choose between Starlink and Globalstar services for texting or to contact emergency services.
- Currently, Starlink is limited to text messaging, but there are plans for data and voice support in the future. This service is U.S.-only at the moment, unlike Apple’s Globalstar which operates globally.
A significant feature difference is that while Apple’s service requires the phone to be pointed skyward to find a satellite, Starlink works automatically, even from a user’s pocket.
Both services are intended for use in remote areas without cellular coverage, like hiking trails, but they are not operational where traditional mobile networks exist. Most current iPhone models support Apple’s satellite feature, with plans to extend this to the Apple Watch Ultra later this year.
Apple has not publicly acknowledged the Starlink support in its iOS 18.3 update, which instead focused on AI enhancements and bug fixes. T-Mobile updated its website to reflect iPhone support in this iOS version, with plans to expand the beta in February.
SpaceX has sought and received conditional approval from the Federal Communications Commission to begin beta-testing with T-Mobile’s network, starting this Monday, the report added.
