Has anyone purchased on of these SIM cards over the net and used them in your GC8x Aircard? I saw some on EBAY that were "Activated" and had 120 min. of time. What is the deal, can you actually stick one of these babies in your aircard and go surfing or is there a catch, like have to buy a contract for data service? I have wanted to get a Pay-As-You-Go plan like TMobile, but that is for phones only, right now. I also saw a comment on another site saying something like for FREE internet, just get a Easyspeak SIM and go for it. Pipedream or has anyone actually done it but doesn't want to tell??????
