Going to Europe (Germany, Italy, Austria, Switzerland, France) for 3 weeks in September and trying to decide on the best data plan for my phone. I was going to do the SIM card thing but from what I've been seeing, the AT&T global add-on plans are just as cheap (maybe even cheaper than an international SIM). And a LOT less hassle with not having to switch SIM cards in every country. From what I can tell, using the international SIM card from telestial, data costs $0.39/MB. With the AT&T Global Add-on plan, I can get 800MB for $120 which comes out to $0.15/MB. Does that seem right or am I missing something? Then I can get 30 travel minutes for $30 and 50 messages for $10. Getting all of that for $160 seems like a pretty decent deal to me...what do you think? Is this a better option than getting an international SIM card? The only thing I'm worried about is going over the 800MB limit. I plan to use the data sparingly..mainly for directions (Google maps, Viamichelin, etc) and possibly a few emails to contact hotels, etc. Do you think 800MB is enough for 3 weeks?
