Why can't I receive the SMS verification code of CCB?

First check whether there is anything wrong with the mobile phone, such as downtime. It is suggested that the landlord call 10086 1 to see if he can receive a short message reply. If he can receive the notice of the phone bill, it proves that the phone is ok. If there is nothing wrong with the phone, you can try to resend the verification code. If all fails, call 95533 customer service to ask.
