The prepaid phone cards have come to dominate the world of communication in such a way that there may be hardly a caller who has not used these cards ever to make a call.

A caller who wishes to understand the mechanism of operation of a prepaid phone card must know that the technology and subsequently the methodology employed for the use of such cards is totally different from the standard telephone service which one is normally habituated to use. All prepaid phone cards come with a PIN and the initials stand for Personal Identification Number which is incorporated in the card by the company as a security measure. This PIN is the unique feature of every phone card and it is through this PIN that a caller can check for available balance and call for assistance where as the operator can check on the balance of the card’s calling time. In addition, it is the PIN which prevents the hacking of one’s phone card by unauthorized users and provides protection to the caller in terms of monetary value. Therefore, on having decided to use prepaid phone cards, it is imperative for the caller to realize the importance of the PIN and the reason why it should always be protected.

In order to make full utilization of the prepaid phone card, the caller should be aware of all the features the card has to offer as well as the benefits due to which the particular card was chosen as compared to the other cards. A full report can be sought by making use of the FAQ section namely the frequently asked questions as many of the queries would either pertain or be similar to the doubts held by the caller. Some of the common doubts held by new users of prepaid cards are listed as follows:

- Can my prepaid card be used from a pay phone?
- How am I supposed to know the time remaining on my card?
- I would like to know how much I would be charged per minute and how much talk time is available on my card if I make long distance calls.
