Do I need a U shield if I just want to change my mobile phone number or SMS service on CCB's online banking?

Yes, there are always three ways to change the reserved mobile phone number of the bank:

Handle it at the bank counter, go to the bank with your personal ID card and bank card, and fill out the application form for change of relevant information.

To handle online banking, you need to plug in U shield and other devices to directly access the computer, log in to online banking, and then modify the mobile phone number in the basic information in the personal version of bank online banking.

Through telephone banking, dial the customer service phone number of the bank, enter the corresponding menu according to the voice prompt, select manual service, and then complete the information modification with the help of customer service staff.

Remarks: It is very important to reserve the mobile phone number. If the mobile phone number changes, be sure to update it in time.
