I'm not sure if you got the Pm from me explaining it but, Like I said the reason I'm able to use it is because a friend of my back in the states activated it for me there and then I was able to use it here in korea... now I am using my skype number for the number to plug into google voice but thats because I dnt have a cell here so when I get back to the states I will get it for my cell phone but I assume it would work like the other post said ( use VoIP # then use cell) but you'll have to try it out to find out and that means get a friend or someone in the states to help you out.
