Mobile VoIP is essentially a communication technology that people use to send and receive phone calls with the Internet connection on a mobile device. What happen is that for a standard cellular service, the call is placed through the voice network. However, for Mobile Voip, the call is being transmitted over the network of a third party mobile VoIP service provider.

Therefore, when a mobile VoIP call is placed on a mobile device and that transmission takes place over an available network. This means that it does not use the available and costly “minutes” on a cell plan from your carriers. At the same time, the user is not charged any carrier long distance fees if one is to call overseas. In some cases, an applicable charge may be applied by the mobile VoIP provider possibly for data charges.

The ability to make calls without using minutes or incurring long distance charges is truly one of the biggest benefits to mobile VoIP. The charges associated with this communication channel tend to be much lower than the cost associated with the standard use of the cellular phone or other mobile calling device.

Downside is that for mobile voIP to work, it has to be used where a Wifi or 3G data connection is available. There are several companies that currently offer mobile VoIP service, each with their own value proposition in the market. Mobile Voip is a relatively new technology that is slowly gaining adoption.

Voipbuster has developed a MobileVoip application for Android phones. With this new application you can make calls at the same cheap Voipbuster rates you are used to where ever you are through Wi-Fi and UMTS/3G.
