Currently, the update is in beta testing for a limited number of iPhones on the T-Mobile network, enabling users to connect to Starlink for texting in areas lacking cellular coverage.

Unlike Apple's previous Emergency SOS service, which relied on Globalstar, the new Starlink feature allows users to connect without needing to point their phone at the sky.

Initially, the service supports text messaging only, but there are plans to expand to data connections and voice calls in the future.

At present, this satellite feature is limited to users in the United States, with future plans for broader global expansion.

The beta test is currently restricted to iPhones on T-Mobile's network, but T-Mobile intends to extend the program to include a wider range of modern smartphones, including Android devices.

Users must update to iOS 18.3 to activate the new feature, which can be managed through a new toggle in the cellular data settings.

Apple Inc. has formed a groundbreaking partnership with SpaceX and T-Mobile US to integrate Starlink satellite connectivity with iPhones, marking a significant shift in mobile communication.

The iOS 18.3 update also enhances the Genmoji feature and addresses 20 security vulnerabilities to protect user data.

Overall, the iOS 18.3 update significantly enhances the iPhone experience, particularly for users in areas with limited cellular coverage.

This collaboration not only provides immediate benefits for users but also holds the potential for future technological advancements in smartphone capabilities through satellite communications.

Mark Gurman from Bloomberg described the partnership as an 'under-the-radar move' that enhances user experience by eliminating the need for manual alignment for connectivity.

Following rumors of the partnership, Globalstar's stock dropped 11%, highlighting the potential impact of Apple's strategic shift away from their services.
