I would not go to vodafone. I have just changed from vodafone because I had so much trouble. There are so many companies now where it's like a contract but you're not stuck with them for two years. You can change whenever you like. The only thing is, you have to have your own phone. I have two cards in my phone. I use llamaya and masmobil. both are great so far. With llamaya you can get good deals to phone abroad too.
