In two weeks time we will have spent our first night in LA. Looking ahead a question someone might be able to help us with. Our cell phones are very expensive to use outside the European Union, something like $2 per minute, plus a $5 access fee each time for calls and lots more for roaming. We still have my wife's old iPhone 3S. I'm thinking that maybe we could get a SIM card and get a cheap Pay as You Go scheme for say $10 or $20 which is all we are likely to need for the three weeks we are in California. Is that possible?? Any recommendations for company to use?
