1. Positioning drift

Position drift means that the vehicle position does not match the actual position. The main cause of this phenomenon is the poor signal received by the device. This is very likely to happen, assuming that no special attention was paid to the device during installation and that the device is covered with metallic material. When the car enters an area with weak signal, such as a high-speed tunnel or an underground parking lot, there may be no signal phenomenon, which may cause the device location to drift. Under normal circumstances, the owner only needs to stay away from the no-signal and no-service areas and the positioning track of the device It will automatically return to normal. However, if the device is left adrift for an extended period of time, the owner should consider whether there is a problem with the device installation, or contact the merchant directly for device information.

2. The device cannot receive commands

Probably the biggest reason why the largest device can't receive instructions is that the device temporarily loses cell signal. Under normal circumstances, if the gateway does not receive a command temporarily due to poor signal, the owner only needs to wait for a while. If the device does not receive instructions, the owner can directly dial the device's SIM card number to check if the device has a normal connection sound, or if the memory in the card is low.
