- The feature works on iPhone 14 or later with iOS 18 or newer and on Apple Watch Ultra 3 with watchOS 26 or newer.
- Devices prompt users to connect when out of coverage and provide on-screen guidance, with Dynamic Island showing connection strength and a built-in demo teaching alignment.
- Apple says satellite messaging is free for eligible iPhone and Apple Watch users in Japan, though a clear view of the sky and precise device orientation are required.
- The new capability joins Emergency SOS and Find My via satellite already available in Japan, with wider expansion discussed in coverage but not announced.
