Here is my situation. I go abroad from the USA for long stretches, and as I use the pay-as-you-go TracFone, I simply let it expire whenever I leave. Unfortunately Tracfone forces me to get a new SIM card (it's free, but I have to receive it in the mail), so I would not have it available to me when I return to the airport. I would like to start using Uber rather than the more expensive ground transportation that I currently use (it's a 70 mile, $100 trip!) Currently Uber only allows use of its system via a smartphone, so I would need to have a working SIM card to use it.

So I figure that perhaps there are SIM cards preloaded with some time that I could buy at an airport store. I hardly ever use my mobile phone (mainly folks call me and I call them back on my internet phone, LOL), so I wouldn't need a whole lot of minutes to last me a few months. Anyway, is there such a SIM card that it sold at airports?
