Does the questioner want to ask "the reason why the actual card number on the China Construction Bank credit card mobile phone is inconsistent?" The specific reasons are as follows.

1. The card number on the mobile phone is the old card number: If you have changed your credit card but did not update the card number on mobile banking in time, then the card number on the mobile phone is the old card number and is inconsistent with the actual card number.

2. Mobile banking card number display error: Mobile banking sometimes has system problems or the card number is displayed incorrectly, causing the card number on the mobile phone to be inconsistent with the actual card number.

3. The actual card number changes: If your credit card number changes, but you do not update the card number on mobile banking in time, then the card number on your mobile phone will be the old card number, which is inconsistent with the actual card number.
