Hi, Please can you help me?! I live part of the year here in America and part in Barcelona, Spain, I would like to buy a nice unlocked phone that has wi-fi and gps and a camera too. If I get an unlocked quadband phone that I can put my vodafone sim card in that I currently have in Spain, which sim card should I buy for here, bearing in mind I am gone for 4 months at a time? The other issue is that if I don't subscribe to a data plan for the wi-fi will most of the modern phones allow me to turn off the internet part (sorry, I'm not very technical!) so it doesn't use all of my credit on my sim? Any other help/guidance you can offer me would be gratefully received, Thanks.
