I'm looking into getting mobile wifi, but having trouble estimating how many bytes I would need to buy per month. The lady said that 2 gigabytes would allow me to do so many pics, such and such number of emails and then the kicker... 100 internet pages. Can some tech savvy person tell me how this works? So each time I view a page on TFO that counts as 1 of 100? I could use that much in a half hour. This can't be right. Can someone tell me around how many megabytes an average hour of TFO would use? Rough estimate?
