How to unlock iPhone 6, 6S (Plus) for FREE?

Honestly speaking, I have to say this is absolutely a SCAM !!! Apple updated their operating system from iOS 5 and we have not been able to unlock our iPhones using Software since. If you've found a website offering or selling Software to unlock an iPhone, trust me, they're a SCAMMER!!! If its free software, it will be adware for your computer, and if you have to pay for it, well that's even worse! Do not spend your money by paying for those scammers on the Internet.

2. Unlock iPhone 6, 6S plus using a Gevey SIM?

Firstly, I admit that this method is working! But it's not really cool as you think, you will meet some trouble when using it. Let me explain everything about Gevey SIM:
What is the Gevey SIM? Gevey SIM is an invention from China, a very thin piece of equipment which will be connected with your real SIM card from other carrier (Not the carrier which your iPhone is locked) and you put them all into the iPhone and your iPhone will think that you're putting the valid SIM card. For more details, look at the picture below:

So now I think you understand how it works. But what is the restriction when using a Gevey SIM?

1. Your iPhone will not be stable! iPhone may gets trouble such as: overheat, battery lifetime is decreased... And especially the signal is weak and frequently drops out.
2. Not all features will work well, such as: iMessenger, Facetime, Contacts, Phone... You may meet some trouble when activing iMessenger, Facetime. The contact numbers in your iPhone go wrong, can not dialling carrier code like *130#...
3. By inserting invalid equipment into your iPhone, you will void the Apple warranty and if anything goes wrong with your iPhone by using it, you will have no chance to get a new iPhone from Apple as per their policy.

So, I recommend you to continue reading the last method because it's the best way
