Detailed info on how the service works in the Background if you would to know more in-depth info
To unlock an iPhone you need the NCK which is a unique 15 digit key.
Those keys for unlocking are sitting on Apples servers and send to the iPhone via iTunes while the iPhone is connected to the Mac/PC.
Each iPhone has a unique HWID, NORID, CHIPID, (id’s embedded in the iPhone hardware/chips and unique to each phone), the NCK is only working with the one iPhone where the above are matching. The NCK does not unlock any other iPhone.
Trying to bruteforce the NCK would take years even on high-end computers (NCK Brute Force – The iPhone Wiki).
Trying to guess the NCK is limited as well, After 5 or so unsuccessful attempts, the iPhone becomes permanently locked to the carrier – unless you’re feeling really, really lucky, I wouldn’t try it.
Apple has HWID, NORID, CHIPID… of all iPhones sold in countries, where the iPhone has to be sold unlocked. So once a phone of those is connected via iTunes, the apple servers check HWID, NORID, CHIPID and compare it to their database. If the matching iPhone is marked “factory unlocked” the Apple servers send the unique NCK for this iPhone.
Using this service you are sure your phone will never be locked out and you can always use your favourite network simcard with your iphone.
