Im looking at getting wireless broadband as my business is mobile. Im thinking wireless modem as it seems to be the cheaper option for how I use my internet. I think. G fast is $49.95 pm for 1G plus 15cper meg additonal use I use about 1700 mg a month so does this mean I gotta pay and extra $105 per month? or Wireless mobile for $80 per month for 1G Am i understanding this correctly casue that is expensive. Anyone else use wireless, what do you think?
