Is Apple sos a phone call or a text message?

SOS is the emergency contact function of Apple's mobile phone.

The emergency contact function can call for help quickly (such as 1 10 alarm telephone, 120 ambulance telephone, 1 19 fire telephone). This function not only has the function of first aid in case of illness, but also can call the police quietly by pressing the power button in case of emergency. At the same time, you can add an emergency contact to end the emergency call.
