What is “factory iPhone unlocking“?

Factory unlocking an iPhone means “officially – permanently unlock the iPhone“. Your iPhone SIM lock status is regulated in Apple activation server. Everytime you active your iPhone, the iPhone will “ask” the Apple activation server for “What is my SIM-Lock status? Should I let my master use any SIM cards?” Then Apple server will response a signal and your iPhone will follow it to let you use other SIM or not (The same mechanism for iCloud activation lock).

So, factory unlocking iPhone is whitelisting your IMEI number from Apple activation database to change your iPhone SIM-lock status. That’s the way to permanently unlock your iPhone, it will never be relocked even you restore the iPhone or upgrade iOS!

Unfortunately, you can’t do it by yourself, and it’s not free at all. We have to use third party service, there are some providers helping us to do that. But you have to be aware because there are also a lot of Scammers of bad providers out there.
