Kunming, Yunnan called me the other night. I changed my phone number early this morning, but I didn't answer it, did I?

Now, many such scammers, if you reply to the text message, probably agree to your business dealings, such as charging 5 yuan or how much monthly fee, etc! Or how much is the charge for each message! You'd better take a look at the phone bill! I often receive short messages from some advertising companies, and I am very polite, so polite that you can't stand it. The main thing is to let you remember him and find him to do business in the future! In addition, there are scammers who sell black cars or something.
