What should I do if the verification code of mobile banking transfer is wrong many times?

The verification code of mobile banking transfer is to check whether the account is true and valid and ensure the security of the account. If there are many mistakes, it is recommended to check whether the mobile phone number is reserved, whether the other passwords entered are correct, whether the network is safe and whether the mobile phone input method is correct. If it still doesn't work after many attempts, call the bank and ask them to check the reason.
