What is the failure of verification of Apple 12 mobile banking?

Apple 12 mobile banking failed because:

1. There is a delay in the online banking payment network, which makes the server unable to send short messages normally.

2. The mobile phone signal problem caused the mobile phone to fail to receive short messages normally, so the verification of mobile banking failed. These are the reasons why Apple 12 mobile banking failed to verify. Apple 12 is a mobile phone product released by ApplePark 10 am on June 13, 2020 (June/4, 2020, Beijing time 18 am).
