What is the cheapest/ easiest way to communicate from Europe to here in the US?

[lovely_mexican_chik13]

I am going to Europe for three weeks here soon but I'm having a huge hassle trying to figure out how I'm going to communicate from there to here. This is a choir tour and since we don't have a lot of money I am not sure that ANY internet will be readily available for any of us since we will probably be staying in church floors or schools gyms/ rooms. I have AT&T but I went to ask them what I should do and they weren't much help at all. We will be in Czechoslovakia, Slovakia, and Austria. PLEASE HELP WE LEAVE IN A WEEK!!!
