Nimbuzz

Founded in 2006, Nimbuzz is a cross-platform communications platform that lets users make calls, send messages and share files through any mobile device, for free. With more than 100 million users and growing, Nimbuzz is the best way to meet, share and connect with friends and family around the world. Through Nimbuzz, users can make free video and voice calls to other Nimbuzz users, while dramatically reduce the cost of calls to landline and mobile phones. Nimbuzz also lets users chat, call and share files between all major IM communities and Social networks, including Facebook, MSN, GTalk, Yahoo!, and Twitter. At the heart of Nimbuzz is the live Contact list -- an always-on, hyper-connected, dynamic address book, enhanced with "real-time-presence" showing at a glance who's online, offline, busy or away, their status messages, avatar pictures and social community activity. From here, users can launch free and cheap calls between each other, IM chat sessions, picture and file sharing, chat-room sessions, location based services and various other communication and interactive features. The Nimbuzz developer platform provides a channel to more than 100 million users, across 200 countries, on nearly any device.
