The unlock codes I order always work with no issue. I've been using Cellunlocker.net for a good 5 years now.
One time, I haven't used one of my old phones, so I decided to give it away, but when I turned it on, it went back to lock mode. I emailed Cellunlocker.net and they provided me with the code.
Bottom Line: Yes, I would recommend this to a friend
