There are always strange numbers texting me these days. They say they know all my information, and so does my mobile phone number. I suspect that I have been located. What should I do?

Usually this situation is threatening you to ask for money. Ignore him, he can't really treat you. If it really threatens your personal safety or is suspected of financial fraud, you can call the police directly. But it will be annoying to harass you all the time, so there are several ways:

One is to blacken this number and ignore it.

The second is to call the service number of your operator, go to the artificial desk to complain, and let them help you deal with it.

If you are worried that the mobile phone will be implanted with Trojan horse or positioned, go to the setting function of the mobile phone, find the factory settings and resume operation, so that all implanted programs will be cleared. But this has a side effect, all the installers will be cleared or initialized, including the address book. You should make a backup.
