Used to pay for Telephone Services

A cellular phone card for short is a small card, usually resembling a credit card, used to pay for cellular phone services. Such cards can either employ prepaid credit system or credit card style system of credit. The exact system for payment, and the way in which the card is used to place a cellular phone call, depend on the overall telecommunication system. Currently, the most general types of phone cards involve pre-paid credit in which the card is purchased with a specific balance, from which the cost of calls made is deducted. Pre-paid cellular phone cards are disposable. When the balance is exhausted you just buy a new card. Cards acquired can often be restocked. The other major type of card involves a card with a special PIN printed on it that allows one to charge calls to a land-line phone account.
