we will be traveling from utah to italy and it's been about 10 years since we were in europe last- all i remember from our last visit is i came home and my cell phone bill was horrifying:) we are planning to take 1 iphone to europe (rome & paris)- we are leaving our toddler at home w/ family so we need to keep it on and stay in touch, but i'm not sure how to plan on using our phone internationally since we have incoming/outgoing calls + texts + data + maps, etc. that we may be using. last time we were charged for every call that came in, even if i didn't answer. anyone have experience/suggestions? at&t is our carrier.
