It seems what I am asking for is available every where in the world but the united states. We have standard plans through Verizon for our smart phones. However, I have a GSM based tablet. Anywhere the world I go I can buy a sim card and load data on as I need it as use the tablet. Not an issue. Life is grand. In the US, every carrier is like "you need a contract" or "pay as you go" requires you to spend $40/month. Is there seriously no carrier/plan out there that just allow me to buy a sim card and load on data when I need it even if it only lasts a month before it expires?
