I travel with a small satellite emergency transponder that is able to track my progress. On the very remote and more risky sections of the trip I will activate the SPOT Connect tracking. You can check the SPOT Connect tracking map.
This combo allows me to send a message with details of my situation which fits much better with most real world semi-emergencies. Like any emergency transponder the SPOT can also “send the cavalry” with the press of a button. Most troublesome situations don’t warrant a full scale emergency extraction. The device can be light weight, small and cheaper by using much of the functionality of the phone. The setup is more like a limited satellite modem for the iPhone which I already had.
