I currently live in Kuwait and I had issues with Verizon initially getting it unlocked all I could do was use it on wifi with google voice. I dont know much about how it works but once I got the correct code from Verizon global support it worked like a charm. I just updated it today and had to SBF it and was worried I would loose the unlock but it stayed. So the unlock function has to happen on a completely different level. I know when Verizon was giving me trouble I looked into other sites claiming they could crack the code but I dont know if they work.
Also if you do end up getting it to work and want to use data be sure to set your APN. It took me a few weeks and two carriers how to figure it out.
Best of luck
