Apple’s iOS 18 introduces “Messages via Satellite,” allowing users to send regular text messages when no Wi-Fi or cellular signal is available. This feature builds on Apple’s existing Emergency SOS via Satellite, which lets users connect to satellites to contact emergency services. Now, users can send texts, emoji, and Tapbacks over iMessage and SMS through satellites.
To use it, you’ll need to turn on iMessage, ensure both you and the recipient have updated iOS, and enable “Send as Text Message” in the settings. The feature activates automatically when no cellular or Wi-Fi signal is detected, but you’ll need to be outdoors with a clear view of the sky. Sending satellite messages may take a few minutes, and recipients will be notified you’re using satellite connectivity.
There are some limitations: satellite messages can’t support group texts, photos, or videos, and there’s a character count restriction. The feature is available on specific iPhone models, including iPhone 14, 15, and 16 series, but requires the iOS 18 update.
Apple allows users to try a demo of the feature. Although powerful, the system won’t work under heavy foliage or other obstructions.
