Change the mobile phone number bound by mobile banking as follows:

1. Signing customers: You need to bring your valid ID card, any signing bank card or passbook, and your new mobile phone number (it is recommended that you bring a new mobile phone card and equipment) to any CCB outlet or ATM in China.

2. Non-contracted customers: it is not supported to modify the mobile phone number directly at present, and the bound new mobile phone number needs to be reopened after canceling the mobile banking (note: before reopening, it is necessary to ensure that the reserved mobile phone number corresponding to the bank card has been replaced with a new number).
