Emergency SOS via satellite can help you connect with emergency services under exceptional circumstances when no other means of reaching emergency services are available. If you call or text emergency services and can’t connect because you’re outside the range of cellular and Wi-Fi coverage, your iPhone tries to connect you via satellite to the help that you need.
When you use a satellite connection, the experience is different than sending or receiving a message via cellular. In ideal conditions with a direct view of the sky and the horizon, a message might take 15 seconds to send, and over a minute to send under trees with light or medium foliage. If you’re under heavy foliage or surrounded by other obstructions, you might not be able to connect to a satellite. Connection times can also be impacted by your surroundings, the length of your message, and the status and availability of the satellite network.
Emergency SOS via satellite will be available with an iOS 16 software update coming in November 2022.
