I was so skeptic as I have tried other unlocking companies and they were all fraud. So initially I did the standard service unlock and it didn't work because the phone was in contract with AT&T. So the Premium Service unlock was offered to me, which required an additional amount to be paid( I was so scared this was another scam) however I proceeded, I was informed the unlock would take 7 days. To my surprised it was unlock in 5 days, I highly recommend there's services!
