Viber is a free alternative to all known ways of communication - phone calls, e-mails, MMS, SMS, and so on. Of course, the only condition for using this type of software is constant access to the Internet or a large package of mobile Internet data. If you use a smartphone or tablet and have a wireless WiFi home network with access to the Internet, Viber can be an ideal alternative not only for VoIP services, but also for traditional paid phone service providers.
The Viber features a clear, modern and easy to use interface. In the short run, only the Apple device owners could enjoy the benefits of this software, but shortly after its release in 2010, the developers extended their existing mobile service beyond the mobile-only to desktops and laptops. When it comes to mobile devices, the program is compatible with Android, BlackBerry OS, iOS, Symbian, Bada and Windows Phone.
Please note that we must have first configured and registered the app using our mobile phones, in order to log into the desktop version. Let's start with installing Viber 3.0 for Android device ( you can use the same walkthrough to install and configure Viber on other devices since the process is more or less the same ).
