Cell phone plans gave us access to a certain number of call minutes for a set price plus, usually, free nationwide long distance on evenings and weekends. Of course, they also had disadvantages such as sometimes spotty service areas, dropped calls and, all too often, bad reception. Now VOIP is bringing us yet another option for long distance service, promising greater convenience and freedom. We can even consider combining cell phones and VOIP technology. Can these promises be fulfilled?
