This method can track the location of your mobile phone (it is useless to turn it off, but it can also be tracked), monitor your phone and intercept your WeChat. Your phone calls and WeChat content (whether sent or received) will be saved to the computer of a company that provides communication services within a certain period of time before the technical investigation means is started (the exact time is unclear). The technical investigation measures needed for the pursuit. So it is not difficult to find out the contents of text messages and phone calls.
