Basically you'll need to get a country-specific SIM that has data service available. For Italy, the TIM SIM works fine. For Spain, I found Vodafone store all over the place and purchased a SIM from them (after I was in Madrid). Istanbul had a couple of cellphone vendors at the airport, including Vodafone - I did not get a SIM card in Istanbul as the hotel had fully free internet & I was scheduled for a short stay.

For VOICE in an unlocked GSM phone the Telestial Passport card is fine. But not for data.
