Inexplicably received the mobile phone transaction code bound by China Bank.

What if I need to cancel the mobile phone transaction code under special circumstances? A: On the premise of fully understanding the bank's online banking security protection measures and related knowledge, being familiar with the use of the bank's online banking dynamic password card, and having a high sense of fraud prevention, if it is really necessary to cancel the authentication of mobile phone transaction code under special circumstances, you can go to the bank's outlets to consult and handle related business with your ID card and online banking related account.
