Barablu promises free calls from cell phone to cell phone via a downloaded software client. The only slight hitch is that you have to own a WiFi enabled mobile handset. Kind of limits the field a bit, don’t it? Not to mention the fact that finding a usable WiFi zone when travelling is about as easy as kissing an alligator.
Barablu is a free calls community. It is the worlds first company to offer free mobile-to-mobile (Wi-Fi enabled) calls. It also gives you free calls from Mobile to PC, PC-to-PC and mobile to IP phone. Along with this you also get free chat from mobile. All you need to do is to download the Barablu dialler from http://www.barablu.com/downloads.htm. Ask your contact to do the same and once you both have the dialler installed on your computer or mobile (Wi-Fi enabled) you can talk to each other for free.
