Why do you require a second real-life authentication? Why do you say my mobile phone is not normal?

Because the number selection is judged by the system through artificial intelligence and does not involve manual intervention, if you have had an abnormal call or abnormal trajectory or abnormal traffic, you may judge that there is a certain risk and need real person authentication to return the call. You can use Unicom APP for self-authentication, and it will not be affected after the authentication is passed.
