After the successful installation of 4g wireless tracker purchased in bulk, enterprises or dealers generally send SMS messages through the online platform or send instructions through the APP to remotely control and locate terminals, but sometimes the remote control fails. Check whether it is caused by the following reasons:
1. 4g wireless tracker terminal equipment is powered off
Unlike wireless positioning products do not require an external power supply, the first thing to check when the wired positioning terminal fails to wake up is the power supply problem, once the device loses power, then the locator is unable to work.
2. 4g wireless tracker terminals cannot receive signals
If the 4g wireless tracker is in a weak environment, the locator will not receive remote commands, or the SMS gateway will be delayed, you will need to restart the device and reconnect.
Third, the equipment SIM card is stopped
The same reason as using a mobile phone, if the SIM card is down, it will also cause the device to be unable to receive remote instructions.
Four, instruction error
Send the wrong command, positioning terminal can not achieve the operation.
