Mate, don't create multiple threads for the same issue...
If it isn't officially enabled by ASUS for your carrier, you can do do yourself by making some build.prop edits, and root isn't even needed.
I cannot tell you more. You'll need to research it on your own, but this should be enough info to go off on. Of course, any changes you do are at your own risk.
