What does China Construction Bank mean by sending a text message saying that your reserved mobile phone number information has been modified?

It means that your bank reserved mobile phone number has been changed.

When you go to the bank to modify the reserved mobile phone number, you will send a text message to remind you that it has been modified. If I didn't handle it myself, then someone else modified the reserved mobile phone number of the bank card and provided their own mobile phone number, or the bank staff made a mistake and entered the wrong number.

This reserved mobile phone number is generally used to receive a verification code when using fast payment, and may receive a verification code that has nothing to do with you.
