Question: viber is it really free?
Answer: Viber-to-Viber calls and messages are totally free. Viber uses an Internet connection (3G, 4G or Wi-Fi) to make calls and send messages. Viber uses data, so there may be charges if you are abroad and using roaming, or if you have run out of data on your plan. ... Calling a number that isn't on Viber is not free.
