Viber is a chatting application that took the world by storm when it was introduced a few years ago and has since managed to offer good quality voice calls.

It offers excellent chatting services and free calls, as long as you have a good internet connection – either 3G, 4G or Wi-Fi connection. Many prefer Viber for making free calls despite the fact that it does not offer video calls. These are some of the reasons that have contributed to its success.

Easy Activation Procedure

To use Viber, you need not go through a long registration procedure. Once you have downloaded and installed it on your device, you only need your phone number to activate it. You will then receive a message that has an activation code. Once you enter the activation code, you can start making calls to your contacts that are on Viber, for free.


Most people prefer moving around with everything they need, when they are on the move. Viber is perfectly suited in this case, because it is a primary mobile application. Most of the other free calls providers are not easy to move around with, because they are not popular on mobile phones. A case in point is Skype.

Data Consumption

Viber is a voice on IP (VoIP) application and the main objective of VoIP is to help minimize on costs. Generally, mobile VoIP is more expensive compared to desktop VoIP because of mobile connectivity. Mobility requires either 3G or 4G data plan in which the billing is done, depending on the amount of data used. Users are, therefore, cautious about data consumption of their mobile VoIP calls. Viber uses about 250KB per minute on calls. Other mobile VoIP services use several times more than that making Viber a more convenient option.


The Viber application is compatible with and can be installed in various devices. It can be installed in Blackberry, iPhone and any other smartphone that uses Windows or Android operating systems. Once you have installed it in either of the listed devices, you can proceed to call and send messages free of charge without interruptions.

Low Battery Consumption

Viber does not use a lot of memory when it is running in the background, meaning it consumes less battery power. It gives the battery greater battery life and better performance. This is very convenient for users as they do not have to worry about their phones going off when they are using Viber to make important phone calls.

Simple interface

Viber’s interface is simple and easy to use. Making a phone call is as easy as selecting the call option, after you have selected the person you want to call. You can also check out the call log to see the recent calls that have been made or received. If you have a missed call, it will be displayed on your notification bar making it easy to call back the person who missed you earlier on.

The above points are some of the reasons why you would opt to use Viber to make free calls.
