GSM-outsideUS-iPhone 5.
It unlocked my iPhone 5 in a day. Service worked as promised.
I wanted to unlock my contract At&t iPhone 5. After a lot of research on IMEI unlocking and people who did this service I went with this page since it was cheaper and had good reviews. I paid the fee, got the micro-sim card from a telephone company outside the US that uses GSM 850, inserted the sim card and my phone got service and data from that carrier so it worked.
