Unicom emperor entered. . High score! ! ! Urgent! ! urgent

The answer upstairs is irrelevant.

You asked about monitoring the boot, not mobile phone monitoring.

These two are completely different concepts.

Monitoring startup is a basic communication function.

Whether it is Unicom (WCDMA) or mobile (GSM TD-SCDMA) telecommunications (CDMA2000).

In these communication systems, there is such a functional entity that the base station has been monitoring the status of your mobile phone (out of service area, etc.). ), that is, as long as you install a mobile phone card, it will report your location (here refers to the location area in communication) or status.

Only Unicom has made this business public.

This business is not a value-added business.

So feel free to use it.

Baidu Steel Enterprise Union will answer your questions wholeheartedly.

hope this helps
