Apple has activated Messages via satellite for users in Japan. The feature lets you stay connected when you have no cellular or Wi-Fi signal. You can use it on the iPhone 14 or later and the Apple Watch Ultra 3.
You see a prompt to connect to the nearest satellite when you try to send a message without network coverage. Once you connect, you can send and receive iMessages, SMS texts, emojis, and Tapbacks. The process works directly from the lock screen or inside the Messages app.
Messages sent through satellites stay protected with end-to-end encryption. This keeps your conversations private even when they travel through space instead of a cell tower.
Here’s what Apple said today in its announcement.
Japanese users already use emergency SOS via satellite and location sharing in Find My. Messages via satellite now join these existing tools and give users another option to stay in touch during outages or remote travel.
How It Works
The feature requires iOS 18 or later on supported iPhones and watchOS 26 or later on the Apple Watch Ultra 3. After you connect to a satellite, your device guides you with on-screen directions. Dynamic Island even shows connection strength and tells you to turn left or right if needed.
Apple also includes a built-in satellite demo. You can use it to learn how to aim your device toward a satellite before you lose signal. This helps you understand the process before you rely on it outdoors.
Satellite messaging continues to be free for supported iPhone and Apple Watch users in Japan.
