I am having problems connecting to Viber today and when trying to call my contacts for free, it says Viber service unavailable or being blocked. I thought it was just me or my connection, but some of my friends and relatives started asking me if I having the same issue. So that confirms me that I am not alone.
For the benefit of those who are not familiar with Viber. Viber is an mobile application that lets you use your Blackberry, Windows Phone, Nokia, Bada, Android Phone and iPhone to make free calls and send free text and photo messages to other Viber users, on any device, network and country!
What I did is tried to re install an older version because lately I notice delayed sending of Viber messages, drop calls and unable to use their free calls. I was thinking maybe their recent Viber update is not that good. After re-installing Viber it is supposed to send me a 4 digit validation code, but I guess that too is affected.
Oh well, Lets just hope the maintenance will be over soon, everything has been fixed and more improvements are being prepared for millions of Viber users just like me.
