Why is there no SMS verification code for online payment in China Construction Bank?

There may be more reasons why the mobile phone did not receive the SMS after the online banking payment of China Construction Bank, as follows;

First, there is no SMS service on the mobile phone.

Some banks charge for short message service. If this service is not enabled when you apply for a card, there will be no SMS notification.

Second, cell phone signals.

If the cell phone signal is unavailable or weak, you may not receive the SMS notification in time, but you may receive it after a while, depending on the cell phone signal environment.

Third, there is no mobile phone number in the online transfer information.

Generally, you need to receive SMS prompts when transferring money online, and you also need to write your mobile phone number. If you don't write your mobile phone number, you may not receive SMS notification.
