Key Points
- Apple’s iOS 18.3 update lets T-Mobile customers send texts via SpaceX’s Starlink satellites. The service is currently in beta testing.
- Beta testers have started receiving messages confirming their access to satellite texting.
- Users must update to iOS 18.3 and activate the feature in their cellular data settings.
- The service currently supports only text messaging, with plans to add voice and data in the future.
Apple has introduced a groundbreaking update with iOS 18.3, enabling T-Mobile customers to send text messages even in areas without cellular coverage. This update supports SpaceX and T-Mobile’s direct-to-cell satellite service, which is currently in beta testing. The service opened for signups in December, allowing select users to send texts via Starlink’s satellite network.
Previously, this technology was only available on specific Android devices, such as Samsung’s Z Fold and S24 and certain models running Android 15. Meanwhile, Apple has already offered satellite-based messaging through its partnership with Globalstar. However, this new update expands iPhone users’ access to satellite texting through SpaceX’s Starlink network.
According to Bloomberg, some beta testers have already started receiving messages confirming their access to the service. These notifications inform users that they can now stay connected by sending texts via satellite from virtually anywhere. The message prompts iPhone users to update to iOS 18.3 to “start experiencing coverage beyond.” Once updated, a new toggle will appear in the cellular data settings, allowing users to activate the satellite messaging feature.
Currently, the service is limited to text messaging. However, beta testers in remote areas without traditional network coverage can still send messages using Starlink’s satellite connectivity. T-Mobile and SpaceX plan to expand the service in the future, eventually adding voice calls and data capabilities.
This collaboration between Apple, T-Mobile, and SpaceX represents a significant step toward universal connectivity. By integrating satellite-based communication into iPhones, users in remote or rural areas will soon have more options to stay connected without relying solely on traditional cell towers.
