These folks are persistent, effective, and professional. They provided an unlock code for a phone that AT&T claimed Samsung did not have a code for. The first method they tried yielded no result, but after checking back with us they tried a second database and were successful. It wasn't super quick but was within the quoted time. They stayed in contact on progress. I am going to use Cellunlocker for a second phone. I highly recommend them!
Length of Use: Less than 3 months
Bottom Line: Yes, I would recommend this to a friend
