Truphone has unveiled new application for Android-enabled mobile handsets, introducing Wi-Fi calling on this platform. The new Truphone for Android release 3.0 integrates a full VoIP engine allowing users to make free calls to Truphone, Google Talk and Skype users when both parties are in Wi-Fi, in addition to low cost calls to landlines and mobiles.

The company said that the Android application is compatible with the HTC G1, HTC Magic and HTC Hero. Compatibility with other Android models with firmware 1.5 or above, including the Motorola Droid and the Nexus One are expected to follow soon.

According to Truphone, its application also includes integrated multi-headed instant messaging support for Skype, Google Talk, AIM, Yahoo! and MSN customers, allowing users to switch between different conversations and keep in touch with others whichever IM service they use.

In addition, the application allows customers to make low cost calls on their mobiles when out of Wi-Fi. When out of Wi-Fi, the application works by making a local GSM call to the Truphone gateway that is if a customer has a bundled package of minutes this call is often free, otherwise is charged as a local call, from where the call is then routed over the Truphone network, the company said.

Geraldine Wilson, CEO of Truphone, said: “The Truphone application allows customers to make free or low cost calls from their mobiles whether they are in or out of Wi-Fi, whether they are using the Android, iPhone, iPod touch or Blackberry devices. The cost savings, convenience and unparalleled call quality on Truphone makes it really easy to stay in touch with friends, family and colleagues all over the world.
