If the location of your device is not found for a long period of time or is inaccurate even when locating using GPS (GPS icon is displayed on the LAMAX Tracking device), please check whether there is enough free data or credit on the SIM card in your LAMAX Tracking device. When data runs out, most operators will significantly slow down or turn off data transmission, and as a result the location data may be very inaccurate or non-existent. LAMAX Tracking devices require access to the Internet for proper positioning.
