Hi all, I've got a iPhone 5S on verizon, unlocked. Will be in Europe, specifically the Netherlands and Austria for a few weeks in December, and will be looking to get a local sim in each place. Interested in data, don't care about voice. Will need for navigation and Skype/facetime. I have two questions. First, once i get the sim card, how will the phone get activated on that network? Do i need to plug the phone into a computer with iTunes and a wireless connection? Meaning, if i don't have my laptop/itunes with me, it won't work? Or is there some other way? Also, any suggestions on data providers in either of those places? Many thanks.
