International messages should be included or there should be a separate plan with international messages included. Remember that many of us live literally minutes from an international border.
Many of us are looking for lower monthly payments. Although unlimited options are cool, they are not worth it for some. For example, I'd rather pay $10 less and get a reasonable number of minutes, just enough to avoid getting dinged for every minute. I'm sure such a plan with limted number of minutes (200, 400?), but reasonable data alllowance would be attractive to many, and would be good value compared to the competition.
