The international plan does include all data. If you use the $20 (I think that is the cost) I believe you are covered completely as far as email and browsing. If you take the per KB international data browsing can get really expensive. The only reason I set my users up with the per KB plan is because it only applies when they use it (and we tell them no internet browsing!!!) and I don't have to turn it off and on all the time when they come and go -- which you can do with the unlimited plan.
