Be aware that if you completely remove long distance from your phone line, you will often be charged what is called a “No PICC” fee, sometimes amounting to 5 bucks or more. You will then be required to use a “dial-around” code (remember the proliferation of the “10-10-321” “10-10-880” commercials a while back?) in order to make LD calls.
It would be better to just switch to a LD plan that doesn’t charge a monthly fee, and then never make LD calls from home.
