I got my LG G6 in the U.S. from T-Mobile in May 2016 and had to travel to Europe within three days upon purchase. I didn't know that my device had to stay in the U.S. for at least 40 days to be eligible for permanent unlock. I made 5 temporary unlocks, each consisting of a month and my LG then got completely locked.
I had to send my LG to the U.S. and get it back after 40 days to make it work. Then I found Cellunlocker.net and thought to give it a shot.
I am very happy I did! They said the phone would take 3-5 working days to unlock, made payment on Thursday, and my phone got unlocked by Monday. I highly recommend this site!
Bottom Line: Yes, I would recommend this to a friend
