Another important point this device does not include gps as the name implies sales uses the lbs systemwhich is a localization system using cell towers through the gsm network the location is notas presise like a gpsdepends on the amount of towers installed all over the terrain giving a margin ofbetween 50200 meters but at least gives an idea of ​​where the device is
