I'm off to Europe on a HOG tour tomorrow, iPad safely packed for travelling. I phoned O2 today about data roaming. The answer? Nothing doing. "Buy a local micro sim card" was the only advice.
So I need to find a shop in each of France, Belgium, Germany & Austria to buy a micro sim card and swap as I go along. Somehow I think not Jonny Foreigner! I'll have to hope the hotels have wifi.
