A. Here is a quick summary: • Interstate Calls are calls made from one state to another. • Intrastate Calls are long distance calls made within your home state, but to an area outside of your LATA or local calling area. Usually Intrastate calls are calls made to a different area code than your own. • Intralata Calls are long distance calls made within a specific area that are usually billed by your local phone company. Intralata calls are not the calls you make for free every month in your home area. They are long distance calls, usually made within your same area code. Changing your Intralata calling does not change your local phone service in any way. But it does usually save you a lot of money on your phone bills.
