Apple did not immediately respond to a request for comment, but SpaceX CEO Elon Musk seemingly confirmed the partnership on X, tweeting: "Medium-resolution images, music, and audio podcasts should work with the current generation Starlink direct-to-phone constellation. The next-generation constellation will support medium-resolution video."

T-Mobile's cellular Starlink beta program was initially restricted to five Samsung phone models. But the carrier has quietly expanded it to select iPhones running iOS 18.3.

Starlink support appears to be a secret iOS 18.3 feature for iPhones, some of which now support satellite communication services from SpaceX — but only for users invited to join public beta testing of the service on US carrier T-Mobile. This supplements Apple’s existing satellite services supplier, Globalstar.
