This is something for Verizon travelers to consider. There is an International Data plan that gives you 20Mb for $20/month. That isn't a lot but it's more than enough for most emails (unless Aunt June sends 10Mb pictures of Fluffy) and some browsing or App usage.
I activate it when I'm traveling and then cancel it after I return. That way I'll only be paying $20 when the same amount of data would be around $80 on the regular plan.
