vehicle location tracker remote switch can not be sent out what is going on?

With the development of science and technology, vehicle location tracker is no longer only a simple positioning monitoring function. Users can also remotely control our vehicles through the locator, which itself can be switched on and off remotely.

But recently some friends are asking, why their own locator remote switch machine can not be sent out, what is going on?

The reasons why the remote switch of the locator can not be sent out are mainly as follows:

1,the locator power off

The wired vehicle location tracker relies on the car's power supply to power it. Once the device is powered off, the device cannot receive remote instructions, and it cannot be switched on and off remotely.

2,The SIM card stores too much information

Too much information stored in the SIM card may cause the device to fail to receive the remote on-off command. Therefore, the information stored in the SIM card must be cleared periodically.

3,the SIM card does not open SMS service

If the user wants to send a short message to switch the phone on and off remotely, then the SIM card SMS service must be opened. If the SMS service is not enabled on the SIM card, the device cannot be remotely controlled by SMS.

4,Instruction error

If the remote switch command cannot be sent out, or there is no response, you can check whether the command is sent incorrectly.
