GPS2SMS is a way of sending GPS coordinates by means of SMS text messages. The receiver, for instance the POI66 server, stores those coordinates and generates a Google map showing that GPS location.
Nowadays you'll find a whole bunch of dedicated devices capable of send SMS text messages containing GPS coordinates (we call that GPS2SMS). Reasons to use those devices could be enhanced safety, like in the case of vehicle or vessel theft, or when you enter an unsafe area. Some people like the idea of creating a digital track of bread crumbs by sending their GPS position by SMS text message.
