A telecommunication credit card used by consumers to pay for telephone and
cellular services. Calling cards employ a prepaid credit system
through the use of prepaid calling cards. If a card allows consumers to
add funds to the card, it is a refillable card and will usually have permanent PIN.
Other types of calling cards have a defined number of calling minutes available.
Users enter the calling card code into their cellphone to activate the time and
dispose of the card. Calling cards are a
common way for consumers to pre-pay for long distance telephone services, and
are also commonly used for
Pay-As-You-Go cellular phone plans.
