Doesn't Hubei Bank need SMS verification to change the reserved mobile phone number?

The reserved mobile phone number needs to receive the verification code.

It is recommended to activate and reset the password at the bank counter.

You can check whether the mailbox is full first. If it is full, please delete some information. I still can't get it after deleting it. You can change the machine or card to see if it is a hardware factor. You can try to test whether it can be received in other places and see if it is the reason for the weak local signal. After removing the above reasons, it still cannot be used normally. You can contact the local manual customer service to deal with this problem. There is no charge for mobile phone numbers reserved by banks. Bank SMS notification number charges 2 yuan -3 yuan/month.
