Japanese Arrows X F-10D on AT&T


I saw on the a page that someone here has ordered and wondering if the japanese phone will work on the AT&T Network, I dont want to high jack the form...

I received my phone and popped my sim into the phone itself since it uses a MicroSim but it shows that I have no Service available I was wondering if anyone has any clues in getting this to work..\

thank you :)
