I plan to take my iphone with me on a trip to Rome, Florence, Venice and Paris. My plan is to remove the SIM from my iphone and use WiFi and Skype on my iphone while I am in Europe. My Questions: 1.In the USA, we are used to free WiFi but am I correct in assuming that it will cost me to use WiFi in those locations in Europe? I plan to use WiFi for email retrieval and Skype. 2. Has anyone use Skype on an iphone to call the USA from Europe? If so how was the phone connection? Thank you.
