One of the main features of a phone card is its simplicity in use. There are no long drawn procedures either in its purchase or use. It can be bought like a commodity of daily use and can be used like a credit or debit card of a bank.
The caller purchases the calling plan by paying the predetermined value of the card from the calling company. On purchasing he is allotted a PIN number which is the key for operating the card. Once the caller dials the PIN, he is connected to the toll free calling zone. Then he can dial the required numbers like the country code, area code and the telephone number he wants to call. After the talk, he will hang the receiver and the call charges are automatically deducted from his calling plan. When the balance reaches a particular value or at any time he feels it necessary, he can buy additional calling time from the same company and the calling plan gets recharged. Recharging can be done online or by buying appropriate amount from any of the retailers dealing with the calling plan.
Some callers are in the habit of frequently calling a particular country. Then they can buy the calling card of that particular country. By this the caller will be eligible for special discounts on calling cost. The caller can use the card for calling through VOIP. When the caller is in some other country, he would find it not economical to call through that country because of the huge charges for international calls prevailing in that country. In that case, he can make use of call back facility which enables him to call through his calling company and at considerable lower rate.
