Virtual VoIP calling cards are a great way so save money on calls. Virtual Calling Card users either connect to their own VoIP account or to a prepaid account with a VoIP provider, and then use that network to make cheap calls over IP rather than over the PSTN or cellular networks.

The vast majority of virtual calling card calls terminate internationally, but virtual calling cards are also a great business tool to save money and maintain a professional appearance if you need to make a business call when you are not at home or in the office.

In order to user a virtual calling card, sometimes called a virtual calling code, the user must use the phone to dial a special number, usually a toll free number, given by the VoIP provider. This number connects to the nearest server, which, in turn, connects over IP to the nearest server to the receiving phone, which connects the call. The phone call is on the PSTN for the shortest distance possible, essentially turning a call halfway around the world into a local call.

There are many benefits to using a VoIP calling card. One is price. Plastic calling cards tend to have connection charges and maintenance fees, which VoIP providers typically do not have. In addition, the calling rates are often cheaper that plastic card rates. Another benefit is sound quality. By using the VoIP provider’s network, you get a crystal-clear digital signal, rather than an analog signal that degrades over long distances.
