Is there still a need for 1-800 Numbers?

“1–800” numbers, toll free numbers that allow people to call a business without incurring long distance charges, date back from the days when the monopoly ATT would charge you for each call outside your very local area, with long distance charged by time of day and day of week.

But I haven’t paid long distance charges in twenty years, and nationwide calling seems to be a basic part of mobile phone plans.

Does anyone pay for long distance within their own country? Are toll free numbers still a business necessity?
