What is the difference between a toll free number and a prepaid calling card?
assistant
A toll free number is a number that is free to call from any phone, regardless of whether you have a calling card or not. A prepaid calling card is a card that you purchase and load with money. When you call a toll free number, you pay for the cost of the call, but you do not pay for the cost of the call if you use a prepaid calling card.
