I have tried 5 services and spent lots of money and in the end it is always the same story, "Your phone could not be unlocked". It is an AT%T carrier on my phone which is out of contract.
Which companies did you pay to unlock it that couldn't?
Okay there were two attempts by iPhoneunlocker Pro. One was a feeble attempt using Evaison to jailbreak it and unlock it which failed. Then I was foolish enough to fall for one of those R-Sim 9 Pro thingys that also did not work. Some people swear they work but not on my phone.
Then there was iPhoneunlock, Theunlockdepot.com and Unlock-Code-World.com these were just the ones that were supposed to refund me but did not.
By this time I have figured out (I am persistent) that my iPhone is only going to be unlocked by AT&T so I have given up. I was only so persistent because the party that I bought it from said it could be unlocked as part of the purchase agreement. He offered to refund my money but I got such a good deal on it I decided just to keep it and use it on AT&T.
Since everyone on this forum seemed to be so positive about Ideviceguys I decided to give it one more whirl. Of course they also could not unlock it but they did refund my money promptly.
I would like to report that iDeviceGuys finally unlocked my iPhone 5C! After refunding my money they contacted me and asked for another try they had thought of another idea. No up front money until they unlocked it. Today they contacted me again and said it was unlocked. I slipped a T-Mobile SIM into it and it searched and went right to the T-Mobile network. After 4 previous attempts I had about decided it could not be unlocked but they surprised me and unlocked it. So, no they are not a scam they are for real!
Thanks guys!
