GPS tracker offline. How do I troubleshoot step by step?
Follow this troubleshooting process in order for efficient problem localization:
- Troubleshoot basic hardware: charge, restart the device, or verify power connections.
- Troubleshoot service subscription: check if the service subscription has expired.
- Troubleshoot signal environment: inspect network signal and move the device to an open area.
If the issue persists, provide your device's IMEI number to receive technical support.
GPS tracker often offline or weak signal. Why place it in an open area?
GPS trackers work by receiving radio signals from satellites. These signals require unobstructed straight-line transmission and have poor penetration. Any obstruction can cause problems.
- Metals such as car trunks and metal boxes, plus thick concrete, can completely block signals and make the device go offline. Tall buildings and trees can cause repeated reflection and refraction, weakening signals until the tracker cannot receive enough satellites for positioning.
- Open areas such as car roofs and open parking lots avoid these obstructions. The tracker can receive enough satellite signals faster, reduce repeated satellite searching, save power, and extend battery life.
Simply put, open areas let the tracker receive satellite signals smoothly, fundamentally resolving offline and weak signal issues.
