There are a good amount of mobile messaging applications out there, but today we will talk about WhatsApp and Viber, which come with some nice options and features. After you will read this article, you will have an idea about which one of these two applications is worth installing, but your decision will be also influenced by the number of friends who are already using either WhatsApp or Viber.


Both applications can be installed with ease on your iOS or Android device. Just open the Apple Store or Google Play Store, search for WhatsApp or Viber and install it on your handset. Both applications will identify you via your mobile phone number, which means that you will need to use it in order to create an account on WhatsApp or Viber.

It is good to know that Viber can be also installed on your Windows PC, but in order to log into the application, you will still need to sign up via your mobile phone number.
On the other hand, the WhatsApp application has its WhatsApp Web feature (open the webpage on your computer) and the standalone app, which require you to scan a QR code using your mobile device in order to log into your WhatsApp account on your computer. Unfortunately, you will have to keep your mobile phone connected to the internet and the WhatsApp application will continue to run on your handset.


In the past, you had to pay $0.99 per year for using the WhatsApp application, but the developers have decided to make the application completely free. The Viber application is also free, which means that both applications just need an internet connection in order to function on your handset.


WhatsApp has currently over 1 billion monthly active users, while Viber has around 754 million registered users. We can clearly say that the WhatsApp application is more popular and there are high chances that you already have a good amount of friends who are using it for quite a while.

Data Consumption

You will not waste too much data when you will send messages or photos while using these two applications on your smartphone. However, according to reports, the Voice Calling feature on WhatsApp is using more data than on Viber. So, if you don’t have too much data to waste and want to make Voice Calls via one of these two applications, we suggest you to go for Viber.

Call Quality

At the same time, the call quality is way better on Viber. At the same time, you can only call your WhatsApp friends via the WhatsApp application, while on Viber you can call landline phones via the Viber Out feature, but you will need to buy credit to use it. However, the rates are decent and if you want to make a call to a landline phone from another country, you will surely want to use the Viber Out, as it is pretty convenient.


If you have more friends on WhatsApp, then you will definitely want to install this application on your smartphone. If you are a person who spends a good amount of time in front of a computer, we suggest you to go for the Viber application, as you will not need to keep your mobile phone connected to the internet and the application running on it (as you are required when using the WhatsApp Web feature on the WhatsApp application). Also, if you’re planning to make Voice Calls via one of these two applications, you should definitely go for Viber, because of the quality and the lower data consumption.
