Scam service This is a fraudulent service, like others I was told ' I've just heard back from our unlock team and they just informed us that your unlock has been rejected by AT&T, the official reason for rejecting your unlock is always that there was 'account irregularities'. Whilst they won't specify exactly what irregularities they are, it's usually either that you haven't pay your bills on time in the past or you still owe them money and they're worried about not getting their money from you.' total nonsense as I have never missed a payment, its a scam as they ask you to pay another $99 to get a more advanced service

DOES NOT WORK - DO NOT USE! They cannot unlock a iPhone running iOS 8.3 - they then tell you to downgrade to 8.2 but the software they provide can only work on iOS 8.1 - I want a full refund which they offer but I'm not holding out any hope.

Thought I did my research... But NO This company may not even be anything but an old website. Although it includes the latest IOS and phones so IDK. It is a total waste of money and simply doesnt work at all. total rip off site... STAY AWAY!!!!

doctorSIM is a complete rip-off doctorSIM is a complete rip-off. They gave "excuses" as to possible reasons why they couldnt unlock my iPhone 8+ but none applied to my phone. 100% paid for and under no contract. Left my previous carrier after fulfilling my agreement. Paid they $50 for NOTHING!! DO NOT WASTE YOUR MONEY!!!!

scam I really think they knew this from the start.. Bad news for would-be jailbreakers of iOS 8.2 beta 1 or beta 2—both firmwares are no longer being signed. There seems to be conflicting reports going around about whether or not Apple has killed access to beta 1, beta 2, or both beta firmwares, but I can personally confirm that Apple has shut down access to both. Why is this significant? It’s significant because iOS 8.2 beta 1 and beta 2 were the only firmwares available that allowed users to jailbreak using PP Jailbreak on Mac or TaiG on Windows. So what to do now? The only option right now is to wait it out. There are rumors flying around that TaiG may be holding on to an iOS 8.2 jailbreak, and if the past six months are indicative of anything, I’d say that that’s a distinct possibility. Reports are stating that Apple may drop iOS 8.2 this Monday, so I guess we will see whether or not the TaiG iOS 8.2 jailbreak rumors are true sooner than later. Obviously, if you’re on iOS 8.1.2, or iOS 8.2 beta 1 or 2, you want to stay right where you are. If you’ve updated to iOS 8.1.3, you’re going to have to wait it out for a while.
