Viber Review: Free and Safe Calls and Messages


Viber is an application for mobile devices and computers for free communication between service users. Uses end-to-end encryption for private messages, group chats, and voice calls.

Viber is an application that allows you to make calls and send text messages to any Viber user for free.

Viber for mobile can use a wireless Wi-Fi connection or 3G. The sound quality in the application is significantly better than with a regular call over the cellular network. After your friends join Viber, you will be able to exchange text messages and make voice calls indefinitely. In addition, you can call any phone number at low rates using the ViberOut service.

Viber security
The development team has worked hard to customize your private conversations. Now the team is introducing end-to-end encryption, which will make the correspondence even more secure, as well as the function of hidden chats and deleting messages.

End-to-end encryption
In April 2016, the Viber development team announced the implementation of end-to-end encryption of the communication channel between devices. Work on this innovation has been going on for a long time, and now Viber users have confidence in the confidentiality of conversations without the risk of unauthorized interference. Encryption is supported on all devices, including tablets, smartphones, computers, and is used for both private messages, group correspondence and voice calls.

Users should make sure they are using the latest version of Viber, only in this case they will receive a message that their conversations will be encrypted. The change will be implemented within two weeks, and the gray lock icon will notify about the start of encryption. Additionally, each user will receive an individual encryption key associated with the user's device, which guarantees an additional level of security. You can manually reassign contacts to indicate that they are trusted. In this case, the color of the lock icon will change to green. If you see a red padlock, there is a problem with the encryption key. A violation can mean that the user has changed their primary phone, but in some cases this can signal a MITM attack.

Hidden chats
Protecting privacy is not synonymous with protecting personal information from hackers in cyberspace, which is why the Viber team is constantly looking for new ways to extend control over communication channels. Many family members use the same tablet in which they conduct personal correspondence, and many employees communicate with friends during working hours and want to hide this fact from prying eyes. The new Hidden Chats feature allows users to hide individual chats from the home screen so that other users do not know about the existence of private conversations.
