The apple is lost. What do you mean by emailing that it is being activated?

That is, the mobile phone is being activated by swiping the card, but even if the ID lock is opened, swiping the card is useless.

The ID lock turns on the "Find My iPhone" function under iOS 7 and later systems. When the system is in the state of "find my iPhone", you need to reactivate the Apple ID account on the bound mobile phone to enter the desktop, otherwise the mobile phone will fall into the infinite loop of "brush-activation-brush-activation" and become the legendary "brick". Apple introduced the ID lock function in the iOS7 system to protect Apple users.
