iPad while traveling Earlier this year I was in Egypt during the uprising. Before I left the USA I subscribed to a one month use on Vodafone. My iPad worked great when I was able to get on-line so I was able to let my family know I as okay. My question is, why did the iphone work if the ipad didn't? I'm getting ready to cruise from Istanbul thru the Med. Will a simcard allow me to use iPad on land if not on the ship?
