Great customer service and they diden't stop until I was unlocked. I had an AT&T Galaxy S3 that I bought used and wanted to use on another carrier. Had previous owner contact AT&T for the unlock code and was given same code each time but neither one worked. So I tried one of the "Free Unlock Code" sites without any luck either. At this point I gave in and went with the first unlock code company mentioned in one of the Android forums. I signe dup with GSMLiberty, submitted my phones info, paid my fee and several hours later my unlock code came in an email. Sadly it did not work so I let their customer support know. Seems in the process of attempting the unlock with AT&T and the crappy free sites code, I altered some settings. GSMLiberty had me make some slight changes (step by step instructions) and next thing I know I AM UNLOCKED. Highly recommend GSMLiberty.
