"Toll-free" refers to the 800, 888, 866, 877 series of numbers that do not incur "toll" charges for a long distance call on landlines.
Landlines and cell phones work differently. Landlines are tied to a specific location, "local" calls are unlimited for the basic monthly access fee, then you have a long distance plan tacked on for calls outside the local area.
Cell phones have a monthly allowance of minutes, regardless of where you call to or from, and the term "long distance call" is meaningless - whether you care calling locally, long distance, or to a "toll-free" number, it still uses your minutes.
Hope that explains it.....
