CCB etc SMS reminds the phone number to change.

CCB's Dragon Card ETC credit card is the same as all other CCB credit cards. If you change your mobile phone number, you can only bring your ID card and card to any CCB outlet for modification.

The mobile phone number of CCB credit card cannot be modified by telephone or online banking. Now the information of mobile phone number is very important. Basically, all online payment and verification information must pass SMS verification code. In case the mobile phone number is tampered with, the card will be dangerous. So now CCB stipulates that the mobile phone number of a credit card cannot be changed on the mobile phone, and other information can be changed on the mobile phone.

Only when changing the mobile phone number, the cardholder must go to the CCB outlet with his ID card and credit card.
