Nimbuzz!

Nimbuzz is a social application that lets you chat in real time with your friends and other users anywhere on the planet. From its simple interface you can contact friends from different social networks as long as they've also downloaded the tool on their PC, iOS, or Android.

With Nimbuzz, you'll also have access to chat rooms full of users that you can start talking with without having to add them to your friends list. This application also lets you create private chat groups with your friends, and it can sync Facebook chat with each contact's status, so you know who's online and who isn't.

You can also make phone calls after you verify your number. These calls are free, and the quality of the connection depends on your Internet plan, since they are VolP conversations, like on Viber, Skype, and LINE.
