This summer (May-end of July) I will be studying abroad in Europe. Unfortunately/Fortunately, not just one country. I will be traveling to the following countries: Hungary, Czech Republic, Austria, Italy, Belgium, France, England (Where I will be the majority of the time), Ireland, Spain, The Netherlands.
1. How do I go about so I can my iPhone 4s it overseas?
2. Is there a time of SIM card that I can use in ALL of these countries? (I would like one relatively cheap...are there any that exist with prepaid minutes/data time?)
