1. The SIM card in the car GPS tracker is in arrears.

Solution: Contact the network operator to pay before restarting!

2. The GPS tracker is out of power.

Solution: When the GPS tracker is turned off or powered off, it will go offline. The first step is to dial the device's SIM card number with a mobile phone. If it cannot be connected and there is no response when sending a text message to the device number, it is because the device is powered off or the power supply line current and voltage are unstable.

3. The communication module (GSM module) of the GPS tracker is malfunctioning.

Solution: Contact the manufacturer to replace the GSM module!

4. Located in signal blind spots, such as underground parking lots or areas with weak tunnel signals

Solution: This is a common situation where the platform cannot receive information from the vehicle GPS tracker. It is recommended to leave the area with poor signal.

5. The antenna of the car GPS tracker is broken.

Solution: It can only be replaced!

6. Poor SIM card contact;

Solution: Reinstall the SIM card

7. The sensitivity of the GPS tracker module has decreased, making it unable to locate.

The sensitivity of a GPS receiver is mainly determined by two aspects: first, the gain and noise performance of the entire signal path at the front end of the receiver, and second, the algorithm performance of the baseband part. Among them, the front-end of the receiver determines the signal-to-noise ratio when the received signal reaches the baseband part, while the baseband algorithm determines the minimum signal-to-noise ratio that can be tolerated during the modulation, capture, and tracking processes.

Solution: Choose a manufacturer with high sensitivity

8. The GPS tracker is installed near metal objects, and the device cannot receive GPS signals from satellites.

9. The device is in a shutdown state (not turned on or running out of power)

Solution: Put the device in a power on state; Log in to the monitoring platform (mobile app, computer platform) to check the battery level and determine if there is power;

10. The server did not receive the reported data

Solution: It may be a problem with the device of the car GPS tracker, or it may be a problem with the server. You can contact customer service in a timely manner to clearly state the situation where the device does not report data or is offline, in order to better solve the problem.
