So I'll be traveling to South Korea in a few weeks. I'll be staying there for 2 weeks. I can't WAIT. Will be the first time traveling outside of North America. Anyway, I need a data plan. I use A LOT of data. I'm looking for a plan with at least 2GB of data, possibly 5GB. Since AT&T is extremely expensive, would it be best to pick up a prepaid data account from a SK carrier? I heard that this can be done at an airport? Thanks. I can't go anywhere without data.
