Greetings,

I know there are a ton of SIM-related posts in this forum and others, but I've got what I think is a fairly unique need, and would like your input.

Back in May I jumped on that infamous Italy/Central Europe/China fare mistake/fuel dump, and in the middle of November will be spending 2 nights each in Rome, Budapest, Prague, Amsterdam, and Beijing. My dad will be joining my wife and I on the European legs of the trip.

I've got a need to use data in at least 4 countries (I'm willing to forego China), primarily so that we can search for restaurants reviews and navigate medieval city centers without getting lost (for the record, I do enjoy getting lost in medieval city centers, but not, for example, at the end of the day when I'm trying to get back to my room). Because my wife and I will probably be exploring at a different pace than my dad, we'll probably also call each other fairly often.

What we'd probably need, then, is a SIM card that would allow us to browse the internet in at least 4 countries fairly affordably and that would allow the two parties to contact each other. I'm not worried about phone calls nor text messages to/from the US.

It seems like we might just end up getting a few different SIM cards in different countries. Does anybody have a better recommendation?

Just FYI, we've got a pair of unlocked "iPhone 4"s. And no, I don't have T-mobile.

Many thanks!
