Why can't the bank card of Shang Hui Bank receive information when it is transferred out, but it can be received when it is transferred in?

The specific reasons are as follows:

1, network delay or server communication delay makes it impossible to receive SMS.

2. Blocking strange short messages is set, and the number may be blacklisted.

3. Save the bank number to the privacy space.

4. The communication delay of the third-party server may result in the inability to receive the verification code message.
