I received an error message about the bank card.

The mobile phone number used by user A has been used by other users B before. Before user B stops using it and logs off, the Everbright bank card associated with this mobile phone number is not unbound, resulting in the original mobile phone number being reminded by SMS when user B uses Everbright bank card to spend money.

The mobile phone number reserved by other user B in the bank is wrong, which is exactly the same as that of user A, or the bank staff made a mistake when entering the mobile phone number and entered the number of A. ..
