Of course, it should be noted that if the normal WeChat chat does not involve related cases and does not violate the law, then no one has the right to monitor, monitor and track. 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). So it is not difficult to find out the contents of text messages and phone calls. Ordinary people don't have to worry about using WeChat normally. Be a good citizen and don't do bad things, so others won't monitor your chat records. The police can check the WeChat records. If the content of WeChat involves criminal cases, especially the investigation clues of important criminal cases, the public security organs at or above the county level may take technical investigation measures against the mobile phone number. 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.
