The iPhone’s hidden Emergency SOS feature can be triggered by pressing the side button five times quickly. This action automatically calls 911 and shares your live location with emergency services and designated contacts, offering fast assistance during distress.
The feature has been enhanced recently with Emergency SOS via satellite for iPhone 14 series, allowing users to send SOS messages even without cellular or Wi-Fi signals. The system connects through Globalstar satellites to nearest emergency dispatch centers.

Users can enable this in the iPhone’s settings, add Medical ID data, and emergency contacts for a comprehensive safety profile.
For safety off the grid, keeping an older charged phone sealed in a plastic bag can still provide emergency calling, even without a SIM card, making it a smart precaution when hiking or traveling.
