          Packet-switching networks allow you to dial a local phone
          number to connect to BBSs and online services around the
          world. However, not every telephone in the U.S. has local
          access to a packet-switching network. Below are some of
          the best known packet-switching networks. Call them to
          determine if they have a local number for your area and
          for instructions on how to use their service.
          
          If you intend to do lengthy (over 100K) file transfers
          (upload or download), then packet-switching networks may
          have some drawbacks. File transfers are often slowed down
          on packet-switching networks. For lengthy file transfers,
          regular long-distance telephone carrier lines are often
          superior. However, if most of your online activity
          doesn't include lengthy file transfers, then packet-
          switching networks offer considerable savings.
