To be able to make SOS calls, you need to add your ICE (In Case of Emergency) details.
Press and hold the SOS call key for a few seconds. The phone calls your first ICE contact. If the contact doesn’t answer in 25 seconds, the phone calls the next contact, and keeps calling your contacts until one of them answers the call, or you press . Note: When the SOS call is answered, the phone goes to handsfree mode. Do not hold the phone close to your ear, as the volume may be very loud.
