I would ask a sales rep about the $40 unlimited roaming data plan. It works on CDMA in more places than you think. Only bummer thing is....they won't activate it for an EVO........
Anyways, I'm gonna kick and scream the next time I fly to Japan to get that plan!!! There's gonna be a lot of kicking and screaming. hehe. I mean most of the coolest apps are for traveling!!!
Anyways check on that $40 plan. I just asked them about it and its there and can be used by eligible phones in do-able areas! lol
