<p>I need help regarding “pay as you go phones.” Please excuse some of my foolish questions but we have never used a Sims card. We plan to buy a phone in England and are confused on buying the cards. Do you need more than one card for calling locally and another for international? If you need different cards, do we need more than one telephone or can you change it back and forth. I read where one lady had three telephones she used so I am really confused. Thank you for any help you can give us. Our granddaughter will be in Harlaxton next semester.</p>
