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.

Sprint Unlock - Worked. I needed a Sprint unlock. Previously, I attempted to do this through Sprint but got the customer service run-around. I researched unlocking services, and I thought this seemed like it would be reliable. I paid the fee as advertised ($30). It took about 4 business days, and I received and email confirming the unlock. The phone is now correctly unlocked. Thank you.

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.

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.

100% iron clad guarantee means nothing to them Their site says they have a 100% iron clad guarantee and they claim they will you give you your money back if you aren't happy. I invoked this and the customer service rep was beyond rude. Think all caps emails that have no explanations and just say the word "NO." When I tried to post reviews on their "happy" facebook community, they blocked it. I think this site is kinda a scam or has the worst customer service policy I've ever experienced. I'd warn anyone away from them if possible.
