@TheCPHguy -
Sometimes 3G reception could be low, and this is something we cannot control. Naturally this affects Viber's call quality and results in disruptions and broken sound.
We are continuously trying to improve our handling of 3G, so you can expect better performance as newer versions of Viber are released.
Please note that having full 3G reception doesn't mean your internet's bandwidth is at the maximum expected. When you see a "full reception bar", it merely means that physically, your phone is covered with the cellular signal.
When it comes to the bandwidth itself, your connection could still be slow due to various different reasons, such as being in an area with many other users from the same provider, thus congesting the network.
Meanwhile, WiFi- WiFi calls on Viber should generally be very clear and are free of such disruptions.

Please try removing Viber, wait 24 hours, reinstall and try again (make sure you try both the SMS and the automated call options).
In addition, you may try to register to Viber with a different number (for example - your home landline number, a friend's number, etc.), in order to determine whether the problem is specific with your number, or a general one.
