My construction bank card will be prompted by SMS every time it is transferred, but I haven't received the letter. Why?

This service is a short message from the bank. It is usually opened with the mobile phone number you filled in when you apply for a card, and you will generally be asked if you want to open it. The first thing that happened to you was that you filled in the wrong phone number and didn't fill in your number. The second is the bank input error.

To solve this problem, you must go to the business outlets in person and bring your ID card and bank card to change your number!
