China Merchants Bank Card is bound with SMS notification, and I want to change my mobile phone number to remind you. What can I change after dialing 95555? I still don't understand after calling several times. Hello, if you apply for the professional version of personal banking, please log in to the professional version, click "Account Management"-"Customer Contact Information Modification", and modify the reserved telephone numbers of all the notification services of one card according to the prompts (if you do not apply for the professional version, please bring your valid account opening certificate and one card to any outlet of our bank for maintenance).
