WiFiMobile today launched a Mobile VOIP service on the Nokia S60 handsets which enables users to make free calls to each other over Wi-Fi regardless of location. The WiFiMobile service is available at www.wifimobile.com. Using the basic service users can call other VOIP users completely for free. A premium service is also available that permits calls to be made to ordinary landlines or mobile phones at heavily discounted costs. This service may be of interest to users of funky new devices like the Nokia N95 which runs on S60 and is GPS-enabled.
