Changsha Bank can&;t change the reserved number on the mobile phone, because to change the reserved mobile phone number now, first of all, it is necessary to make real-name authentication of the mobile phone number, and the name of the real-name authentication can only be modified by myself, which requires the staff of Changsha Bank to review, and at the smart counter, the staff of Changsha Bank can only modify it successfully, but there is no Changsha Bank staff working on the mobile phone, let alone the staff of Changsha Bank to review and authorize, so Changsha Bank Card can&;t change the password on the mobile phone.
