Can't believe it worked! I tried AT&T's official unlock procedure without success, then a couple of the bargain unlocking services. Nothing worked. Finally I bit the bullet and paid only slightly more to Keys2iPhone.com. It worked! I now have a fully functioning unlocked iPhone. I should have come here in the first place and not wasted my time being frustrated by everyone else.

Long wait, zero service I had to wait 12 days to hear back from Keys2iPhone, only for them to tell me that my phone couldn't be unlocked and tried to up-sell me to a different service. Looks like the reviews for most carriers are good, but if you want a T-Mobile phone unlocked, go somewhere else.

iPhone 6 Unlocked with 24 Hours I was a bit skeptical at first trying one of these third-party unlocking services. After dealing with AT&T for over a week trying to them to unlock my iPhone, I decided I would try Keys2iPhone. Within 24 hours of submitting my request, I received an email saying "Your iPhone is now unlocked!" Sure enough, when I popped in the SIM card from T-Mobile it no longer said 'Invalid SIM'. I don't normally write reviews, but I was extremely satisfied with the service I received when I thought that I would be stuck with a locked iPhone with no help from AT&T.

Very Fast and Super Easy I intially tried another service myimeiunlock.com which was a total waste of time and money (currently waiting on my refund) was 10$ dollars cheaper I guess you get what you pay for, anyway I continued my search and it led me to Keys2iPhone which hands down was quite easy to pay for and get it going. Total time for my Att iPhone 6plus to be unlocked was 1 day, thanks again.

Amazing Service and Got my 6 Plus unlocked while in contract I had an urgent international trip scheduled and was exploring the options of buying a cheap phone in the travelling country.. but then tumbled upon this post and read the reviews. At morning 1:30 signed up for this service and by same day evening 6:40 PM got my phone unlocked. I was skeptical in between how would they do it but who cares did the steps listed in the email and voila.. got the congratulations message in iTunes. If you are in AT&T you can surely give it a shot and they did what they promised. I will highly recommend keys2iphone
