I went to 3 different cell unlocking companies on the internet. All 3 searched their databases and came back with code not found. After hearing about cellunlocker on youtube from mobiletechreview, I decided to give it one more try. They processed my order and they emailed me an unlock code about an hour later. I put in the code and got my LG F60 unlocked on the first attempt. The other nice thing about the site is they are much cheaper than some of the other sites I went to.
