Apple is adding a limited form of satellite connectivity to new iPhones that lets users send an SOS even when they’re off the grid, no dish required. While it won’t allow ordinary data, voice, or text, it will alert emergency services with your circumstances and location.

In case of an injury in the backcountry or some such situation, users can activate the emergency SOS feature if they have an iPhone 14 or 14 Pro, which have an updated wireless chipset that allows it.
