Viber, a mobile messenger app that allows users to make phone calls and send text messages and images, also gives up plenty of user data to anyone who wants to listen.

As part of our commitment to user privacy and security, all chats on Viber are secured by end-to-end encryption. End-to-end encryption means that data (all types of messages, photos, videos, voice and video calls) is encrypted (or scrambled) the moment it is sent from one device until it reaches the intended recipient.

As a cross-platform instant messaging and VoIP app, Viber enables you to call, video call and message other Viber users for no matter where you are. Viber uses your 3G, 4G or Wi-Fi internet connection to enable you to call abroad for free no matter where you are.

Viber is free to use when it comes to Viber to Viber VoIP calls and messaging. WhatsApp is free for the first year. Once the first year is over, the cost of using WhatsApp is $1 per year. You can call people who don't have Viber using the app but it will cost you about 1.9 cents a minute.
