This 4G GSM and GPS tracking solution will locate and track the whereabouts of your vehicle in realtime via the Internet on a computer, Smartphone or Tablet. Easy installation via your vehicles OBD port. Once you insert your 4G Sim card (not included), it will start sending the vehicle's GPS coordinates via the 4G LTE network to the free online tracking service, which shows the location on Google Maps. It can also SMS longitude and latitude coordinates to up to 3 mobile phones, as well as alerts when the vehicle exits a pre-determined area (not via SMS though) or when the integrated shock sensor has been triggered. There is no setup or on-going tracking charges. You only pay for the GSM sim card and service.
