Just now, someone+I asked for my mobile phone number and said to add me to WeChat. I received a short message and a verification code, and then I told him.

-I haven't heard of adding friends to ask for verification code. Maybe you registered or paid something with your mobile phone number. An acquaintance. Let's ask what we do with your mobile phone number.

Now registration is also the main verification code. Payment is also the main verification code. Don't trust others too much if you are not an acquaintance.

Above, hope to adopt.
