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.

Super quick service Super quick service. They were unable to unlock my iPhone XR but they let me know in less than 24 hours of ordering and were prompt to refund my money. Will definitely use UnlockUnit in the future if needed.

It worked! It worked! I was highly skeptical of using this company (and all others) but after many phone calls where ATT and Samsung were bouncing me back and worth without truly understanding what a network PUK was, I decided to use it and I was not disappointed!!! A couple of days and they sent me both codes (PIN and PUK). Their web page may have some issues: make sure to click only once for the payment and then check whether you have been charged. Even if it looked like it was still loading, my transaction was complete and everything went through smoothly.

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.

Great experience! 1) Keeping me updated on the order status was great, I had daily messages on what's currently going on with my order. 2) Delivery time was as promised 3) What could be improved: I've received 2 unlock codes, 8 digits each, concatenated together producing one 16-digits code. It took me a while to figure out why the code doesn't fit into input field on the device. After trying to insert only first 8 digits it worked smoothly and the phone was unlocked successfully.
