Apple Activates Messages via Satellite in Japan

The rollout marks Apple’s first non-emergency satellite service for everyday messaging.

Overview

  • iPhone users in Japan can now send and receive iMessages and SMS without cellular or Wi‑Fi, with emoji and Tapbacks supported and end-to-end encryption maintained.
  • 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.
