What is the reason why Apple's mobile phone download software was verified?

1; It may be that the Apple ID account has not been activated for verification. It is recommended to open the email address of registered Apple ID account and receive Apple verification email for activation verification.

2. It may be that the information of Apple ID account is incomplete. When logging in to the Apple ID account, see if you need to add content. After completing the information, try downloading after logging in.

It may be caused by an error in the mobile phone system. Log in again after canceling the Apple ID account, or turn off the phone and restart it.
