A smart watch medical alert system has 2 components: 1) a smart watch worn on the wrist with it's own internal cellular SIM and 2) 24/7 monitoring at an emergency response center. When the button on the watch is pressed, the smart watch sends a signal to the emergency response center. The operator will ask if you need help over the 2-way speaker built into the watch. They will dispatch EMS to your location using GPS coordinates and notify your emergency contact list.
