Settings -> Notifications -> Enable 'Use system sounds' -> Notification sound set to 'Silent.

Turn off your system sounds via control panel. Only a few steps.

Android Galaxy S3 - Disabled 'Use System Sounds' in fact disabled everything. Still getting a sound notification with incoming messages. I just want the icon to appear.

Viber mirrors your device's notification settings.
iPhone users:
Turning incoming message sounds ... via notification center:
Setting> Notifications> Viber> turn "Sounds" off.
Good luck!

To turn off the incoming message sounds go to Settings > notifications and disable Use System Sounds. You can also disable Outgoing message sounds from the same screen.
