With iOS 18.3, iPhone users with T-Mobile can connect to Starlink satellites. T-Mobile Starlink is in beta and requires signing up. It currently supports text messages and contacting emergency services when you don't have cell coverage.

Elon Musk confirms Apple quietly adds Starlink to iPhones in iOS 18.3: medium res images, music, audio podcasts should work fine, next-gen will be faster.

In 2022, Apple became the first mainstream smartphone maker to add satellite connectivity to its mobile devices, debuting a new Emergency SOS via Satellite feature in the iPhone 14 lineup. Now, it’s taking its satellite features in a new — and arguably more useful — direction with support for the SpaceX Starlink network.
