A credit card has only one reserved mobile phone number. If this mobile phone number changes, it will be sent to the new mobile phone number when receiving SMS, mobile phone bill and other SMS services. At present, it can be modified at the counter of the branch to which the card belongs: please bring your credit card and your valid certificate to the counter to modify it. You can also modify the mobile phone number through the wealth management version of online banking. When applying for online banking, we need to send a verification code to the reserved mobile phone, and modify the reserved mobile phone number of the credit card in real time after verification.

The above contents are for your reference. Please refer to the latest business changes announced by China Bank official website.

If in doubt, please consult the online customer service of China Bank or download and use the mobile banking APP of China Bank to handle related business.
