How does China Merchants Bank change the reserved mobile phone number? I heard that you can change it yourself with a software of China Merchants Bank, and the bank card is all in one.

If you use China Merchants Bank savings card and apply for online banking professional edition, there are two mobile phone numbers that need to be modified separately.

1. After entering the professional edition, please click the horizontal menu "All-in-One Card"-"Account Management"-"Modify Contact Information" and make changes according to the prompts. This number is used for: one-card receiving SMS notification, card number password payment SMS notification, popular mobile banking transfer verification, etc.

2. The professional version of the reservation number requires you to bring a valid account opening certificate and card to any outlet of China Merchants Bank for modification. This mobile phone is used for professional version of transfer, professional version of payment, certificate recovery and receiving verification code.
