What should I do if I prompt "Mobile phone number has been used" when CCB mobile banking is opened?

If "mobile phone number has been used" is prompted when opening mobile banking, it may be that other customers filled in their mobile phone numbers incorrectly when handling mobile banking, or that other customers used their mobile phone numbers to open mobile banking services and failed to cancel their contracts with our bank after changing their mobile phones. To cancel mobile banking, use mobile banking to sign in the mobile editor "QXSJ" and send it to 95533. After the system returns the short message, reply to "QR# verification code" for confirmation according to the prompt. Please pay attention to cancel the result. Please try to open the mobile banking service again after the cancellation is successful. (In case of business changes, please refer to the actual situation. )
