also remember when a huge selling point for cell phones was how many (or few) long distance minutes were included with your plan? i almost can't even wrap my mind around the concept of long distance or collect calls.
Moreover, before everyone had cell phones there were those commercials that would make fun of you for dialing 0 to make a collect call, they would be like dial 10-10-321 or 10-10-9000 idk there were a few companies out there
