On Monday I leave for a 10 day trip to Europe (Holland, Germany, France, and Monacco) for the World Cup and to visit family. Between now and then I am hoping to switch from Verizon to Cingular (or possibly T-mobile) and get a quad band phone. I would like to use this phone on this trip (and a larger, 3 month trip that is planned for next summer) but I have no idea how cell phone service works over there. I have been to Europe a lot before, but have never needed a cell. I know the major companies are O2, Vodaphone, and T-Mobile (there may be more, please correct me if I am wrong) and what I would like to do is get my new quad band phone unlocked in the states (about $20) then get some sort of pre-paid SIM card in Holland. What I am wondering is how on earth do I go about getting a cheap SIM card with pre-paid minutes- and is it even possible? If so, what prices am I looking at? Also, what networks in Europe are GSM and if I buy the card in Holland, will it work in France? Any help you could give would be much appreciated, especially because I am going to buy the phone today, and I want to make sure I get the right one. Thanks!
