fring offers a mobile solution to making cheaper calls based on the comforts enjoyed by lovers of VoIP services such as Skype and text messengers like Google Talk and MSN. It enables users to make cheap mobile internet calls, transfer all contacts from internet messenger services and engage in multiple conversations simultaneously (which I must admit was too difficult and pointless for me. If I talk to someone I don't want them talking to someone else at the same time.). All your PC-based contacts can be merged into one long list which is very useful and 'presence status' lets you know when they are available. Of course, the most important detail is the pricing. fring is free software which is great news and offers significantly cheaper calls than normal mobile rates. Check the website for details but from what I can see, local and international calls are free using WiFi connections, and very, very cheap for 3G and GPRS callers and to send an SMS. That all sounds very good to me. While PC-based solutions offer a completely free package, if you need to look for a mobile-alternative then fring appears to be leading the way.
