National plans offer the use of the cellular phone anywhere in the United States. As long as you stay on their network,
there usually is no roaming charges. Some offer National Long Distance in there plans so there are no long distant charges.
These are based on a fixed number of minutes per month, with a specified amount
per minute for calls over that amount.
Local plans usually offer local or extended local calling areas for a fixed number of minutes per month. If you don't travel
and don't need long distance coverage these plans are usually cheaper than the National Calling Plans.
