The iPhone 15 series introduces satellite calling, letting you make emergency calls even without cellular or Wi-Fi. This guide shows how to activate and use it when you're truly off the grid.
📡 What Is Satellite Calling?
- Satellite calling lets your iPhone connect directly to a satellite when you're out of regular network coverage.
- Primarily for emergency SOS use or location sharing in remote areas.
- Available on iPhone 14 and newer, but iPhone 15 improves speed and signal tracking.
