Making calls using Viber to another Viber account is free, as long as you have a Wi-Fi connection. If you need to call another person who does not use Viber, you have to pay the appropriate call charges. Viber has a feature called Viber Out, which you can use to make calls with Viber to any outside number in most countries. You will need credit balance on Viber though, which are bought with real money, to make these calls.
We provide Viber Out Credit Balance in appropriate rate!!!!
