Truphone confirmes that its mobile VoIP service is supported on three new Nokia handsets: the Wi-Fi-equipped Nokia E61i, Nokia E65 and Nokia E90 models.

Truphone enables Wi-Fi-equipped mobile phones to make internet-rate phone calls (VoIP calls) over Wi-Fi connections. When the handset is not in Wi-Fi range it reverts from being a 'Truphone' to being a normal mobile handset, so people need only one device.

"The new Nokia E61i, Nokia E65 and Nokia E90 phones will be very popular and Truphone works on them from day one," said James Tagg, CEO of Truphone. "With other manufacturers also starting to put Wi-Fi on handsets, 2007 is the year that mobile meets the Internet - and that means Truphone VoIP," he added.

The Truphone client software has completed the Symbian signing process and is available for all new and existing Nokia Wi-Fi VoIP handsets.

Last week Truphone revealed interoperability with Google Talk, announcing that Google Talk users can connect with Truphone mobile handsets anywhere in the world for free. Calls between Google Talk and Truphone are free because they are pure VoIP calls and take place entirely over the internet.

Truphone is free to download and there are no monthly subscriptions or hidden charges. Truphone-to-Truphone calls and Truphone-to-Google Talk calls are always free; other calls are charged at characteristically low internet rates. Until the end of March 2007, calls from the UK to landlines in more than 40 countries are free, while USA customers can call across the USA and Canada for free.

Truphone announced its beta software for earlier Wi-Fi-enabled Nokia mobile handsets in September 2006. It is already available on the Nokia E60, Nokia E61, Nokia E70 and Nokia N80 Internet Edition handsets. Truphone for other devices will follow soon.
