1. The GPS tracker is turned off and the power is off: The mobile phone number of the locator is dialed through the mobile phone. If the prompt turns off, this is the case.
2. There is no mobile phone signal from the GPS tracker: The mobile phone number of the locator is dialed through the mobile phone. If the prompt cannot be connected or is not in the service area, this is the case. Park the car as far as possible in a better signal condition. The position of the positioner should not be too close, and there should be no metal objects to block it. Place it in the car as far as possible. (In areas with no cell phone signals such as underground garages, tunnels, and remote blocking, the Locator will be offline.)
3, GPS tracking device phone card arrears, or mobile phone card package changes, Internet access is disabled. For details, contact the operator of the mobile phone card (for example: Mobile: 10086, Unicom: 10010). Check whether the mobile phone card has owed fees, whether the Internet access function has been activated, whether the Internet access function has taken effect, and whether the package has been changed.
