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 fring, Skype®, MSN® Messenger, Google Talk™ , Twitter and regular phone contacts from one, integrated contact list. fring also supports SkypeOut and hundreds of SIP-based services such as GizmoProject, VoipCheap, VoipStunt, Free World, 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 (see list of supported devices) with Internet connectivity that is already available from your mobile service provider (how do I know?) 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 our website download page – it’s as easy as downloading a ring tone.
fring roams seamlessly between Wi-Fi and 3G networks while bypassing traditional mobile voice and SMS text messaging services mobile-to-mobile calls, mobile-to-landline calls, and mobile-to-PC calls including integration into Skype, MSN Messenger and Google Talk wherever you are. The patent-pending peer-to-peer mobile VoIP technology delivers full-duplex voice quality with rich internet functionality and maximum network efficiency.

How Fring Works?
fring mobile-VoIP network diagram
The fring™ mobile VoIP solution is designed to optimize the embedded internet capabilities within the subscriber's handset. The fring™ solution establishes a Peer-To-Peer VoIP connection between calling parties, enabling true VoIP sessions between fring-enabled handsets and also between handsets and PCs.
fring™ is based on a unique thin-client technology that for the first time enables true VoIP over 3G, GPRS and Wi-Fi networks. fring™ dynamically adapts itself to the optimal network and handset characteristics while enabling seamless roaming VoIP on multiple networks. The dedicated three-sided P2P network architecture has been developed to support near telco-grade voice quality and network efficiency.
fring™ leverages the Internet connectivity traditionally used for mobile email retrieval and web browsing to provide mobile VoIP communications so users can instant message (IM) and make free mobile calls.
