Apple has expanded its Messages via Satellite feature to Japan, marking the service’s fourth supported region after the United States, Canada, and Mexico. The move strengthens Apple’s push to offer communication options even when traditional networks fail.
When an iPhone loses cellular and Wi-Fi access, the device now guides users in Japan to connect directly to a satellite. The interface shows a lock-screen alert and then displays on-screen directions to help users point their phone toward a working satellite. Once aligned, the iPhone sends and receives texts through the satellite link.

How Apple Rolled Out the Feature
Apple introduced Messages via Satellite during WWDC 2024. Soon after, the company released the feature in the U.S. and Canada through iOS 18. Mexico gained support in the iOS 18.4 update in May 2025. Japan now joins that list as Apple continues expanding its satellite services.
The feature requires an iPhone 14 or newer. Apple also sets specific software versions for each region. Users in the U.S., Canada, and Japan need iOS 18 or later. Meanwhile, users in Mexico must run iOS 18.4 or later.
Availability and Current Limitations
For now, Messages via Satellite works only in the U.S., Canada, Mexico, and Japan. Apple notes that the feature will not function outside these supported regions.
The company highlights real-world scenarios where satellite messaging helps users stay connected. People often lose coverage during travel, outdoor activities, or natural disasters. In those moments, satellite messaging gives users a direct communication option instead of leaving them without contact.
Apple Plans More Expansion
Apple continues to invest in satellite technology, and the company plans to grow this service even further. As more nations support satellite infrastructure, Apple expects to bring the feature to additional regions.
Japan’s inclusion represents a significant step forward. Millions of users now gain a backup communication tool that works far beyond the reach of standard networks.
