Emergency SOS via Satellite is a safety feature on some smartphones that enables users to send emergency messages and location information to emergency services using satellite connections when cellular or Wi-Fi networks are unavailable. This technology allows people in remote or disaster-stricken areas to contact help even without traditional phone service. The phone guides users to point their device toward a satellite, facilitating a basic text exchange with emergency responders. This can be crucial for survival in situations where regular communication methods fail.
