What is "switch regional calling area"?

"Switch regional calling area" means that you are giving the new service provider authority to take over your local toll calls (also known as regional calls, or local long distance calls).  These calls are made directly beyond your local calling area, and will be charged at the in-state rate.  You can refer to the front of your local phone book to determine how far your local calling area extends, and when the regional calling area begins.
