What is Unlocky and Who’s Behind?
Let me tell you a short story. It was back in 2012 when I had to visit some friends in Australia. At that time I had a locked Nokia cell phone so I had to find a way to use a Telstra, Australia sim card. Asking Sprint to do an unlock for me I got a big surprise: they told me I have to pay about $50. Really? I had to refuse.
Looking deeper, I found some unlock code providers like doctorunlock or unlockunit. But as they do this business for a living, I did understand them when they also asked me to pay. But then I got the idea: to create something helping me and others to unlock a cell phone free. Within a month Unlocky was in testing.
When I told some friends about what I am doing, they also joined me. We are all web developers (one of them is a well known Romanian hacker who found a vulnerability in Google’s Android software) and since that moment we’re decided to make a pro bono work with Unlocky. Results? Over 1 million unlocked cell phones at this moment.
Unlocky is a cell phone unlock code generator that helps you generate NCK codes by calculating the device IMEI. The unlocking process is pretty simple (like other providers and your carrier also do): once we have your IMEI number, our tool will connect through a backdoor to carrier’s database and then calculating the unlock code.

Among the Samsung unlock code, Unlocky will also generate the instructions to Samsung Galaxy A21 sim unlock. If your IMEI is blacklisted, Unlocky may generate more than one NCK code which can be found on a Samsung unlock code list.
