  If your Queclink GPS GD100 is unable to get a successful GPS fix, it might be due to a weak GPS signal. Try moving the GD100 to a location with a clear view of the sky. Also, ensure that the top surface (the side with the indicator LED) is facing upwards towards the sky.

- A
  Aaron LynnAug 18, 2025
  If messages are failing to be reported to the backend server via GPRS on your Queclink GPS device, there are several potential reasons: * The SIM card may not support GPRS, so try using a SIM card that does. * The APN might be incorrect; you should ask your network operator for the correct APN. * The IP address or port of the backend server could be wrong. Ensure the IP address for the backend server is a valid address on the Internet.

  If the CELL LED on your Queclink GD100 GPS is always flashing quickly, it could be due to one of two reasons: * The SIM card might not be inserted correctly. Please ensure the SIM card is properly inserted into the GD100. * The GSM signal may be too weak, preventing the GD100 from registering to the network. Try moving the GD100 to a location with better GSM coverage.
