The mobile phone inexplicably receives many SMS verification codes and phone calls! Why? Online, etc

Hello, I'm glad to answer your questions.

There are two possibilities for mobile phone to receive verification code abnormally:

① The mobile phone number information was leaked or resold, which led some advertising companies to push verification codes.

(2) Your mobile phone number was bombed by SMS. At present, all kinds of short message bombing use the verification code interface of the website to send verification codes in batches.

In order to prevent this phenomenon, you need to pay attention to the security of personal information in peacetime.
