2. You can log in to the online banking professional edition, select "Credit Card", and then click "Customer Management-Data Modification" to modify the mobile phone number, home phone number, company phone number and company name;

3. Modify the address of family, unit and household registration in "Account Management-Billing Address Settings". Customers who have not applied for the professional version should call the credit card service hotline.

If you have other specific questions, I suggest you call the customer service staff of the bank, hoping to help you.
