Prepaid telephone calls
From Wikipedia, the free encyclopedia
Prepaid telephone calls are a popular way of making telephone calls which allow the caller to control spend and not be tied into ongoing commitments with the telephone operator.
Prepaid phone cards is a service provided by various telecom companies that sell their service in advance. When you purchase a prepaid phone card, you are paying for long distance connection time in advance. When you make calls using the phone card, the card's value is deducted based on connection fee, duration of connection, surcharges and any maintenance charges associated with the phone card.
Prepaid telephone calls are usually implemented in a telephone operators network using the intelligent network functionality. The competitive prices these operators offer are usually made possible by least cost routing and lower overheads than the larger telephone operators.
[edit] Types of prepaid calling
- Telephone prepaid calling cards (commonly known as Phone Cards in the US and the UK) are available from nearly every newsstand and drugstore. They are often the cheapest means of making long-distance or even international telephone calls. Moreover, they offer complete anonymity. Phone cards sold by retailers are live (active) when purchased by consumers. Web sites offer prepaid PINs for calling, thus there is no physical phone card.
- Prepaid calling operators offer services to customers who hold accounts with them and have paid money in advance. The service is typically accessed by the user dialling a toll free number from any telephone (PSTN, call box, mobile phone etc). The user then authenticates himself with the operator by entering a PIN, types in the digits of the number to connect to, and then is connected by the operator. Often these operators have toll free numbers all over the world, so a customer can access the service even when he is abroad.
- Prepaid mobile phones are offered by most mobile phone operators around the world. Typically all the usual mobile phone services are available to prepaid users, except that they have to top up their balance in advance before they can be used. This is done via a variety of mechanisms - vouchers (commonly called "power cards"), swipe cards, debit and credit cards. An IVR is usually provided to allow the user to find out his current balance by dialling a short code. After the balance has been topped up, a user may make calls, send text messages and listen to voicemail in the usual way. For mobile prepaid typically use INAP or CAP protocol.
