Why do I often receive short messages from Kunming, Yunnan, where my mobile phone number belongs?

It's normal. Now there are many such scammers. If you reply to the text message, it is estimated that you agree to the business between you, such as charging 5 yuan or how much monthly rent, and so on! Or how much each message costs! You'd better look at the phone bill!

I often receive short messages from some advertising companies. I am very polite, and you can't stand it. Mainly to let you remember him and do business with him in the future!

There are also those swindlers who sell black cars or something!
