I am looking into going completely mobile with my wireless lap top when I get it. I was wondering whats the best cell-fi internet service provider, with good rates, to do so. I only really know of verizon, sprint, and atnt. I'm guessing there's a few others, but I was wondering which works the best. I am also hoping to not spend over 35/40 a month. Any personal experience with any would help as well. Thanks! -Nick
