With the advancement in technology and science, software like VoIP and calling-cards help greatly in closing the distance between countries and continents. VoIP, or Voice over Internet Protocol, is a new and revolutionary method of converting analog audio signals into digital data, which can in turn be transmitted over the Internet.

Although we have a number of modes to communicate with people, who are physically far away from us, we do not get much of a choice, when it comes to cost efficiency. Hence in today’s competitive and fast paced world, it has become necessary for companies to provide cheap calling cards. They have become quite a fascination to people all over the world, as they help in making calls extremely affordable for destinations, both national and international.

The idea of calling-cards emerged in 1975 in Europe. But it wasn’t until 1987 that calling-cards become available in the United States. Calling-cards were created, keeping in mind the problem of coin shortage. They made it easy to make calls from a pay phone, without using any change.

National as well as international calling-cards ensure hassle-free communication over an IP network. These cheap calling cards use VoIP technology, and can help in making calls to almost any country. A consumer can even avail features like caller ID, voice mails and 3-way conferencing. Prepaid calling-cards made it possible to make calls from anywhere, but still put it on one bill. Consumers could use residential phone connections or pay phones. Another exquisite by-product is country specific calling cards for tourists or students, visiting or studying in other countries.

Due to the huge popularity of calling cards, the market soon became saturated. This forced service providers to come up with innovative ways of selling their services. However, the most effective method was by offering more and more competitive prices.

The presence of cheap calling cards has proven to increase the flexibility and comfort in national and international calling. Having so many options in cheap calling cards, a user now has the option of selecting a calling-card, which suits him the most. A user can also switch connections and providers, based on tariffs and offers provided, as a phone connection is no longer, a long standing commitment.

One wonders how, by providing cheap calling cards, a service provider can make profit. It is done mostly through advertisements printed on calling-cards. Attractive tariffs draw consumers to purchase these calling cards. However, one does not always notice the terms and conditions stating the service charges and other hidden fees, which a provider is entitled to. These fees help the provider to compensate for the inexpensive services provided. There are very few companies that actually make a profit. Most barely break even.

Cheap calling cards are going to be around for a number of years; and service providers are always coming up with innovative ways of selling their services. They will also find new ingenious methods of making profits on these.
