For a complete list call or e-mail. Habit is what most long distance services rely on. They advertise .07 cents per minute but many times charge .10 cents per minute. We are creatures of habit, we pick up the phone and make calls. We have always done it like this, that is what the major long distance services are counting on.

Thay have no idea what the rounding is, what extra charges there are, and how many times they get charged a higher rate. Business's are very deep into habits. Most business's think they must have a major long distance service because they have multiple lines. The local service is the one providing the lines for the incoming and outgoing calls, which long distance service you use makes no difference. This is the next question.
