Apple expanded its satellite communication capabilities with iOS 18, introducing messages via satellite for iPhone 14 and later models.
This new feature, available in the U.S. and Canada, allows users to send iMessages and SMS texts when cellular or Wi-Fi connections are unavailable.
It builds on the infrastructure used for Emergency SOS, but you don’t have to be in an emergency to use it.
When your iPhone detects that it’s out of the range of traditional networks, it prompts for satellite-enabled services, including Messages, Emergency SOS, and Find My.
When off the grid, you can access the feature directly through the Messages app. The system provides on-screen guidance to help you point your iPhone toward a satellite for successful communication.
One key benefit of satellite messaging is that iMessages are end-to-end encrypted, ensuring the same level of security you expect from Apple’s proprietary messaging platform.
However, SMS messaging has some limitations that prevent misuse. For example, while designated contacts, like family members or emergency contacts, can message you directly, other contacts will need you to initiate the conversation.
Apple has included a Satellite Connection Demo in iOS 18 to familiarize yourself with how messages via satellite work.
You can access it by going to Settings > Apps > Messages > Satellite Connection Demo. This feature lets you practice establishing a satellite connection and sending messages, ensuring you’re prepared when needed.
Currently, it doesn’t support Rich Communication Services (RCS), but future updates could bring more advanced functionality.
Whether facing a natural disaster or just off the grid, this service keeps you connected. Best of all, it’s completely free in select areas, which is surprising as Apple usually charges a premium for its services.
