Easy, Quick, Effective for In-contract phone! Tried another service to unlock my AT&T phone, but it apparently didn't work and we only found out after being in Hong Kong and discovering that the pre-paid SIM card wasn't working. So glad we found ATTUnlocker. Started the process on the weekend and it was done before Monday morning. Definitely worth the price.

Excellent Service! Fast and Reliable! A friend gave me an Iphone 5 for free because she was relocating overseas. Unfortunately, she no longer have the receipt of purchase and AT&T would not unlock it. An AT&T rep suggested to use Unlockriver to unlock my phone but after a quick google search they did not have the best name in the industry and very unreliable. After searching through the Apple forum I discovered this company. Great reviews, US based and reasonable rates. I ordered their unlocking service and sure enough they came through with flying colors. Highly recommended! 5 stars,

Awesome When the AT&T Device Unlock Portal and the supposedly cheap eBay services fails you, ATTUnlocker.us comes through with flying colors. My iPhone 6 that I bought off of Craigslist was stuck on a AT&T Next contract and over 50 attempts on the portal and then a few cheap services on eBay, the phone could not be unlocked. ATTUnlocker.us did it in under 3 business days at a fair price. I definitely recommend their service.

Great, Fast and Reliable!!!!! Like many others here, I was a bit hesitant about using a remote unlocking service for unlocking my new iPhone 6. During the entire time, attunlocker would reply to my emails within a day at most. The process took a bit longer for me (6 business days) but well worth the price. After dealing with cheap unlocks on eBay that never worked and reading about others getting scammed, I can tell you all that this is a legitimate unlocking service. I will be coming back straight to them for future unlocks.

Best service ever!! I called around to different places asking if they could unlock my ATT 5s and they couldn't do it because of firmware issues. I then found this website a bit suspicious and thought expensive but they promised 24 hours or less and they did it. I was overjoyed when my unlock went though. Now I am using tmobile all thanks to AttUnlocker.us
