hi- i'm just having a look through the forum, and maybe this will help you- movistar is the service provider. when you get to ibiza and turn your fone on it will automatically search for a new provider -one is movistar or the other one is amena. you will find that your fone operates on one of these networks. i have samsung and LG fones, also a nokia. and the new network has worked on these. i am sure that you don't require a new handset but somebody else is better to confirm this. good luck.
