It really works. I had bought the iPhone X from a friend, but their carrier was at&t. My carrier is Ting which is more of a pay for what you use kind of carrier which I love. But you have to have an unlocked phone and I didn’t realize that my friends phone wasn’t unlocked. After 6 weeks of both he and I trying to deal with AT&T, they stopped making sense of why they wouldn’t unlock the phone. We came to the conclusion that they were refusing to unlock to phone without saying it. I was about to give up. My last ditch effort was to go into a local iPhone store to see if there was anything that they could do. At first they said they couldn’t help, but then they remembered hearing about unlock genie and how one of the employees had tried it. They watch a video with me on it and I had new hope that I would be able to get the phone to work! I went home, made my order and in 3 days I had the SIM card. I was able to follow the directions really easily and within minutes my phone was unlocked. I could not be happier. After over a month of frustration with AT&T and being ready to give up, I was finally able to unlock my phone and give AT&T the bird! Thank you unlock genie!
