1 means that your information has been stolen. Although this situation is very common, it is generally not so careless to send information back to you.

Error in sending information. I have experienced this situation, that is, someone else wrote the wrong information and filled in your mobile phone number when handling the card. You can call the bank and use your ID card information to check whether there is an unknown account under your name. The telephone systems of credit cards and savings cards may be different, so you may have to make separate calls. To be on the safe side, you can also make a personal credit report at the People's Bank to see if there are any unknown cards.

At that time, I received a message that the credit card business of a bank with the suffix * * * had been completed, and I happened to have the card of this bank. I called the credit card center to make sure that my card didn't have this operation and didn't have this card. The bank said that someone else might have filled in the wrong information. Sure enough, after a while, I received a message that the mobile phone number of this card was changed to another similar number.

3 is a liar, who may trick you into calling or going somewhere, but when you go to a bank outlet, there should be nothing suspicious.
