Nimbuzz Mobile, in it’s new avatar for Windows Mobile devices, allows you to call, chat, message, and send files on the go, for free. It combines all your buddies from Skype, MSN, Yahoo, ICQ, AIM, Google Talk and more integrated in a unified contact list.
Like most multiple protocol IM client, Nimbuzz allows you to check who’s online and where, call/group-call, and also send send photos/music/video. Instead of calling minutes, Nimbuzz uses the internet to let you make free international calls to your contacts. You can also register your VoIP account to call your friends on phones.
An interesting feature is Buzz. If your contacts are offline, let them know you’re trying to get in touch by sending them a Buzz. It will start the Nimbuzz Mobile app on their mobile phone.
Nimbuzz Mobile free to download and use. However, if you are not using a free Wifi connection, you would incur data charges on your mobile. Download the application from here.
