Provides MCK defreeze codes as well I locked the phone out with a wrong network Unlatch(NCK) PIN which meant I needed an MCK defreeze code. After two weeks of going round in circles with UK O2 who didn't know what I was talking about - I put an order in with UnlockUnit. One hour later I had the MCK defreeze and NCK codes and was able to remove my phone from the O2 network. Great service - happy customer.

Doesn't work with verizon Does not work on verizon since i got this message "Please do not place order for this phone. We do not unlock phones originally locked to this network. If your phone is locked to this network but you select another network, you are not eligible for a refund"

Authenticatic Website. This website is very legit, and based on my personal experience, when the code was not available for my phone, they refunded my funds as soon as I received the email about the refund.

Good Good: Yes it worked!! Used their service to unlock a at&t locked galaxy s9+ I bought second hand. Bad: I ordered a 1-6 hour unlock to be done at 5pm. Did not recieve a code til 9:35AM. Order number 3017889. FAST service indeed. I would not reccomend the expedited service. In my experience I'd still pay for the service if it's under 24 hrs. But I expected under 6 as advertised.

Excellent Service, great Customer service!!! Extremely pleased with this service! Process was complete and simple for me to use within 48hrs. They are also very supportive and responsive to ANY additional questions or concerns after completing what you pay them for! I will always use this service if needed in the future and you should too!
