The global launch of Viber Out could see the messaging app out-muscling its growing competition in what is set to become a hugely crowded market in 2014. Viber Out gives our millions of users a new way to use Viber and ensures that they can reach any contact at any time, said Talmon Marco, CEO of Viber. We will continue to improve Viber Out, keeping our users connected at the most affordable rates possible. Viber claims that unlike other messaging apps offering the same feature, that its rates will be significantly lower.
