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.

Starlink plans to start beta testing its Direct-to-Cell service. The beta test will include its global cellular partners, including T-Mobile.

T-Mobile partnered with SpaceX last year and launched a beta program for Starlink connectivity last December. However, the company originally only offered the option on Samsung phones. Now, this has been expanded to the iPhone as well.
