fring™ is a free mobile VoIP software that lets you talk and live chat (IM) using your handset's Internet connection instead of costly mobile airtime (GSM) minutes. fring enables free mobile calls over Wi-Fi Internet access or your GPRS, EDGE or 3G Internet data plan.

fring lets you easily communicate with all your VarPhonex and regular phone contacts from one, integrated contact list. fring also supports hundreds of SIP-based services and even from non-SIP enabled handsets, enabling cheap local and international VoIP calls to contacts’ PCs, mobile phones and landline numbers. fring is also enhanced with real-time contact availability (presence) so you can see who’s available before dialing.

All you need to use fring is a 3G handset with Internet connectivity that is already available from your mobile service provider or through your nearest Wi-Fi hotspot. fring does not require any proprietary hardware or airtime, and works with phones purchased through any mobile operator. fring can be simply downloaded into your handset via SMS received from another fringster™ or from fring's website download page.
