"Chat, exchange messages and connect both to PCs and to mobile phones."
As you might have already started to work out, Nimbuzz gives you free calls, messaging, and all your friends in one place. It basically lets you chat, exchange messages and communicate with other users, both on their desktop and their mobile phone.
With Nimbuzz you can chat with your contacts on Nimbuzz, MSN, Skype and Google Talk networks, free and directly from your mobile phone. So, send a text message to your contacts, or establish mobile to mobile or mobile to PC connections.
In the future, the creators of Nimbuzz say that the program will also support AIM, ICQ and Yahoo! message networks. Thus it will become a global communication tool, and for all users. You can even buy NimbuzzOut credits and make low-cost international calls directly from your PC to landlines and mobile phones anywhere in the world.
