How to change the mobile phone number:

Take exchange behavior as an example, all banks change in the same way.

There are two ways to modify and bind the mobile phone number of Bank of Communications credit card: one is to handle it at the counter, and the other is to handle it by telephone.

If the mobile phone left by the cardholder when handling the credit card changes and needs to be replaced, the cardholder can change the mobile phone number at the issuing bank outlet with his ID card.

If the cardholder's original mobile phone number can also be used, you can call the customer service of the issuing bank, and the bank will generally change the bound mobile phone number for the cardholder through mobile phone verification; If the original mobile phone number can no longer be used, the issuing bank will inquire about the cardholder's information by calling the customer service phone of the issuing bank to help the cardholder modify it.

Bian Xiao reminds: Remember to bind fast payment online after modification. If you need mobile phone authentication, you need to modify it.
