Why can’t my iPhone receive the verification code from China Guangfa Bank?

The reasons for not receiving text messages or verification codes are as follows:

1. You can first check whether the mailbox is full, and if so, please delete some information;

2. If you still can't receive it after deleting it, you can change the phone or card to test to see if it is a hardware factor;

3. After eliminating the above reasons, you can try to test whether you can receive it in other locations and see if it is possible. Is it due to weak local signal?

If none of the above problems exist, please contact local customer service to handle the problem.
