Viber is a VoIP tool that allows smartphone users to make free voice and video calls among them worldwide and to share free instant messages with multimedia attachments. It is one of the most popular communication apps in certain regions of the world, but is and has always remained in the shadow of Skype and WhatsApp. With above 1 billion users, Viber is one of the key players on the market. It uses your mobile number to identify you on the network and allows you to communicate using VoIP for free bypassing your mobile carrier. Viber Out allows you to make calls to non-Viber, landline and mobile numbers at cheaper VoIP rates. The app is available for most platforms, including iOS, Android, Windows Phone and BlackBerry.

The Bottom Line

Viber is famous as it makes things free between peers. You have a set of friends that use Android, iOS (iPhone, iPad), BlackBerry or the latest Windows Phone, you get them to install Viber on their devices and register their phone numbers — you are set to make free calls and group messaging among yourselves. This applies even if some of your correspondents are abroad because it used only the internet to channel its calls and messages.

You do not need to register or sign in when using the service. Once you download the app to your device, you are asked to enter your phone number and you are given an access code through SMS, which you type in on activation. You are then identified through your mobile phone number on the huge user-base of Viber.

Group messaging is another thing that is widely used on Viber, but many other apps have preceded Viber in this. The app allows you to select and add contacts from your address book for participation.

The app integrates your phone’s address book and each time you decide to make a call or send a text message to a contact, you are prompted to either place a regular call (or SMS) through your mobile carrier to the contact or to make the call or send the message using Viber. Before initiating anything in the event Viber is selected, the number is verified to see if it is registered with Viber, as free service is allowed only to those.

The app isn’t very heavy on resources and installs quite quickly. It is simple to use. It runs in the background (if you allow it to do so, of course) taking advantage of the multitasking possibility of new smartphones. Viber also allows you to post and send photos and map locations.

Viber does not use your GSM architecture and service to channel the calls and messages. You need to have an internet connection through either Wi-Fi or 3G. Things will remain free if you use Wi-Fi, with chances of maintained good call quality, but you will then be terribly limited in mobility. When you use 3G on the move, take into consideration that you would be paying for each megabyte of data used on your data plan. Some of you, in some regions and with certain operators, might find that the service is blocked because apps and services like this stand as serious threats for mobile carriers.

Viber also has a version for desktop and laptop computers, such that you can remain connected while on your computer. It works on your browser.
