CCB's bank card, a phone number can only be used as a SMS reminder of the bank card?

Your ID card can only open one account, and an account (with multiple bank cards) can only be bound to one mobile phone number.

But a mobile phone number can be used by multiple customers. That is to say, the card under your name can only be bound to one mobile phone number, but this mobile phone number can also be bound to his bank card. However, it is generally recommended that each customer use his commonly used mobile phone number as a reserved mobile phone in the bank.
