Thanks! This is a helpful information. I have searched for the Note II model numbers on Samsung Forums, but this is the most detailed I've found yet. It's interesting to know that the China version is dual sim . Not that I really need it, but I think it'll be useful to those who don't want to carry 2 cellphones all the time.

There are several different models of the Galaxy Note II. Be sure to choose the right one for your network when buying.
