China Bank Gong Hu SMS reminds the second person how to get it.

A bank card cannot bind two mobile phone numbers at the same time, only one mobile phone number can be bound, so only one mobile phone number can receive short messages. When handling a bank card, you should bind the card owner's own mobile phone number to ensure the security of the account. After the SMS reminder service is launched, if the local account balance changes, the card owner can receive SMS reminder. If you need to modify the reserved mobile phone number of the bank card, you need to bring your bank card and ID card to the counter of the bank branch. This business is free and can be done on the spot. It will take effect immediately after the modification is successful. The short message of bank change can only bind one person's mobile phone number. It is impossible for two people to know the account changes through SMS, but one person can bind WeChat and prompt the account changes through WeChat service, so that two people can know the account changes at the same time.
