What's wrong with China Agricultural Bank's commemorative coin reservation without verification code?

The possible reasons why China Agricultural Bank failed to receive the commemorative coin reservation verification code are as follows:

1. Check whether the mailbox is full. If yes, please delete some information.

2. If you still can't get it after deleting it, I suggest you change the machine or card to see if it is a hardware reason.

3. Check whether it is intercepted by mobile phone interception software.

4. Check whether the cell phone signal is normal and try to test whether it can be received in other places.

5. If you use your mobile phone abroad or you can't receive the SMS verification code, it is suggested that you can try again later if the signal network is delayed.

Extended data:

SMS verification code is a communication service that SMS service providers can send to users after accessing the three major operators. Therefore, whether the SMS verification code can be sent to the user's mobile phone normally will be restricted by many factors such as mobile service and SMS gateway.

(1) SMS gateway is congested or abnormal.

In some special time periods, there may be congestion or other abnormal conditions in the SMS gateway, resulting in the delay or packet loss of the verification code SMS.

(2) The number of acquisitions exceeds the limit.

Usually, in order to avoid the bad platform caused by malicious registration, the channel will control the maximum number of times that each mobile phone number receives the verification code before accessing the SMS verification code interface.
