Preliminary information

Before explaining yourself in detail how Viber works, well that you are familiar with all the main features of this service. First of all, it should be specified that, to make a phone call with Viber, you need to install the relevant software and activate an account: two totally free operations. Pay attention, however, to the required requirements.

A device is possible Android, this must have the version 4.1 or higher of the operating system installed on it. In case you want to install the Viber su iPhone or iPad, you will need to make sure this is equipped with iOS 10 or later of the Apple operating system.



However, it is important to know that the Viber app must first be installed on the smartphone to be used on a tablet as well.

As regards the computer, Viber is available for Windows, MacOS e Linux. However, the client for these platforms can only be used if a Viber account has been installed and configured first on the smartphone. You can download the Viber installation file directly from the service's official website. I warn you, however, that you can only install Viber on Windows 7 or later, macOS 10.12 or later and also on some specific Linux distributions (eg. Ubuntu 64 bit e Fedora).

Furthermore, since the services of Viber use the Internet connection, you must make sure that the Internet connection is active on your mobile device or on your PC. As for the Viber client on PC, you must also make sure you have a microphone and headphones, without which you will not be able to make a call. In the case of video calls, however, you will also need to have a webcam.



If you want to know how to download and install Viber and how to activate an account on this messaging service, I suggest you read my guide dedicated to the topic.

Finally, as I have already mentioned in the introduction of this guide of mine, although Viber allows you to make free calls to other users subscribed to the service, it is also possible to call national and international telephone numbers on traditional telephone networks, by subscribing to a pay-as-you-go or subscription plan, using Viber out.

You can, in fact, make unlimited calls to any international number (50 countries) at the cost of 8,99 euro / month. If, on the other hand, you want to call only city landline and mobile phone numbers, you can subscribe to a plan with unlimited minutes a 4,99 euro / month or purchase credit for the pay-as-you-go plan for a fee 0,021 euros / minute for calls to landlines e 0,143 euros / minute for calls to mobile phones.
