UKEYSO iPhones are unlocked with a technique known as "bricking", which basically means that you have to find another way to unlock your phone (other than by buying a new one). There's actually a free method available, but because it's free, a lot of people use it, and it's the method that I'm recommending to anyone who wants to do it on their own. Here's how it works: every time you power up your iPhone, it checks to see if you have another copy of the application installed - if not, it tries to load up your existing copy, and if this doesn't work, it loads the free software.
To perform this operation, simply download one of the free programs called Live SIM Unlocker. You can find it by going to "Products" on your computer, then scrolling down until you see that option. Clicking that option will start to download the software onto your computer. Once it's downloaded, it will install the software on your computer, then let you perform the procedure for unlocking your phone. This whole process only takes a few minutes, and when it's complete, your iPhone will be unlocked!
Now, you may be asking yourself "Why is UKeySoft iPhone unlocking free? ", and the answer to that is simple: in order to provide a quality service to their customers, UKey Soft must make their applications free to use on other devices. After all, that would mean more profits for them - and it would also mean that their software is a great solution for people who have had problems with their previous SIM cards, such as people who have locked their SIM cards up in case they've been caught out by a cheating spouse. So to help those people, UKeySoft has made their unlocking software completely free to download!
