Got Netzero and she went with the 15 buck a month plan. To check usage she looks at a web page on that. No extra apps to install.
Most of the telephone email companies sell their internet usage by the gigabyte. I am considering dropping Frontiernet as my home internet provider since they have gotten so expensive and using a mobile provider. I am retired and use the computer all day, mostly for emails and to check on sites, I never download movies or play internet games, how can I check my usage in GB? I live away from the city so Frontier is the only hardwired option. There must be freeware programs to do this.
