It runs on the latest GPS ublox chip-set, a sophisticated GPS microchip embedded into the heart of the tracker which continually reads its own location from low orbiting global satellites and then utilizes the GSM/GPRS infrastructure open treated by your network provider to transmit its current location you. Then you can operate it on PC (Google map or software Platform).All you need to do is insert a working SIM card
