Users of Symbian OS complained about not being able to send and receive messages free of cost like Android and iOS users. If you are using N8, you know that it is a marvel of technology but you felt peeved when your operator charges lots of money from you for sending messages to your friends and relatives. Finally there is Viber that can cut down on your messaging cost. It is an instant messaging system that works on Symbian technology and makes it possible to send and receive messages to other Viber users for free. Download free Viber for Nokia N8 here.
