Apple Activates Messages via Satellite in Japan

Supported users gain encrypted texting over satellite at no cost when cellular or Wi‑Fi service is unavailable.

Overview

  • The feature is live for iPhone 14 or later and Apple Watch Ultra 3 owners in Japan.
  • It requires iOS 18 or later on iPhone and watchOS 26 or later on Apple Watch.
  • After linking to a satellite, users can send and receive iMessage and SMS, use emoji, and add Tapbacks.
  • When coverage is absent, iPhone prompts users to connect to the nearest satellite, with on‑screen guidance, Dynamic Island status, and a built‑in demo.
  • The launch adds routine messaging to Japan's existing Emergency SOS and Find My location sharing over satellite, with access remaining free on supported devices.
