I am going to Italy this summer and will probably purchase the AT&T data plan overseas. (probably the data and messanging package here) Anyway - if I do buy this for my trip - does this mean that texting someone back here in the US will be as simple as opening the messaging app and texting as usual? And will I be able to access all of my internet apps like facebook, etc.? Also - when I'm hooked to hotel wireless, will I have access to all of my usual US web sites? I've never been overseas and really have no idea what I can and cannot do. Thanks for the help.
