Apple's mobile phone users borrowed ID loans, which caused their mobile phones to be locked. You can try the following two ways to unlock them:

1. The mobile phone "restores the factory settings", and the general setting ceremony chooses to restore;

2. Contact official website to unlock, you need to provide mobile phone invoice, warranty card and mobile phone box, otherwise official website will not provide unlocking service;

3. Try to reset the phone ID by email.

If the above three methods don't work, I suggest that you don't blindly believe in the method of intermediary unlocking, most of them are to defraud the unlocking fee, and finally the mobile phone ID can't be unlocked.
