Using Wifi with GoPhone in Europe

Does anyone know for sure that wifi on GoPhone works while travelling abroad from a wifi hotspot (specifically while in Europe). Common sense would tell me that it does although when I inquired about using goPhone to call from Europe I was told it's a no go. I forgot to ask about the wifi on the same call and I don't think I can stand to hang on the phone again to ask this question. Maybe I'll get a quicker response here. Incidentally, the agent I spoke with re: making calls from Europe at first gave me incorrect info and told me all I had to do was purchase a Passport package for use in Europe. Not until I pressed her two or three times did she admit that there are no calling packages for GoPhone from Europe (and she was supposedly in the GoPhone Dept.!!). Not sure if it was the language barrier or what but more times than not when calling AT&T or visiting their stores, they generally don't know what they talking about...very frustrating!! AT&T needs to either train their people better or hire more competent people. Anyway does anyone know for sure (from personal experience) that phones on the GoPhone plan will definitely be able to connect to Wifi in Europe? Thanks.
