I didn't know where else to post this... I'd like to give my Pi connectivity in the US over 3G or 4G (doesn't matter which) for small quantities of data. I've seen hardware for this (like

What I don't understand is whether I can get a prepaid SIM card that's relatively affordable, i.e. I don't want a plan that has a high fixed monthly price since I won't be using this very much. Does anyone in the US know how to go about this? Thanks.
