The 4G wireless tracker can be remotely turned on and off by collecting text messages. So, what is the reason why the 4G wireless tracker cannot be remotely turned on?

The 4G wireless tracker can remotely control the device to turn on and off through SMS commands, but not all times we can successfully perform remote control. The main reasons why the locator cannot be turned on remotely are as follows:

1、 Positioner power off

The 4G wireless tracker loses power just like our phone shuts down. Once the locator runs out of power, remote commands cannot function properly.

2、 The locator cannot receive a signal

Similarly, locators also need to be located in areas with signals to function effectively. Once the signal at the locator's position is weak, the locator naturally cannot receive remote commands.

3、 The SIM card of the device has not been activated for SMS service

The SIM card of the device needs to have SMS service enabled for remote control to be effective.

4、 Too many SMS stored on SIM card

If the SIM card has enabled SMS service, but the SIM card stores too many SMS messages, it will also cause the device to be unable to receive remote command SMS messages.

5、 Command error

Once users find that their devices cannot be turned on through remote commands, they can eliminate the above reasons one by one to achieve the goal of remote power on/off.
