Cons
Con Has multiple a security vulnerabilities
EFF gave Viber's security 1 out of 7 points in November, 2014. It deducted points because the provider is capable of reading encrypted messages, there's no way to verify contacts identities, past communications are not secure if encryption keys are stolen, the code is not open to independent reviews, the security design is not properly documented and there has not been a recent code audit.

Super insecure. Share messages with the governments. Has access to the private keys ("real" end-to end encryption) Extremely not optimized for battery use. Crappy UI.
