A:AnswerYou can use this with your iPod however you need to buy time/GB's which may or may not fit your needs. The smallest increment you can buy is 1 GB and 30 days. I bought 2 GB and 60 days to cover both Thanksgiving and Xmas/New Years at my inlaws who do not have wireless. It worked great at Thanksgiving and hopefully I have enough left for Xmas.
