Why does Tuqiang Automobile go offline online?

1. When the device is turned off or powered off, dial the SIM card number in the device through the mobile phone. If you are prompted to turn off the device or send any instructions via SMS, there is no reply. This is the case. Confirm whether there is any problem with the power supply line of the equipment, whether the line is powered off, and whether the power supply voltage and current are within the rated voltage and current range of the equipment.

2. The device has no cell phone signal, so dial the SIM card number in the device through the cell phone. This is the case if the prompt shows that it cannot be connected and it is not in the service area. As far as possible, park the car in an environment with good signal conditions. The installation position should not be too close, and there should be no metal objects to block it. Try to be close to the installation. (In underground garages, tunnels, remote jams and other areas where there is no cell phone signal, the equipment will be offline)?

3, SIM card arrears, GPRS service expires or package changes.

4. Consult the SIM card operator (e.g. Mobile: 10086, Unicom: 100 10) to find out whether the card is in arrears, whether the Internet access function is enabled, whether the Internet access function is effective and whether the package is changed. If it is a mobile SIM card, confirm whether the GPRS access point is cmnet.
