EQO Communications has announced the release of a native Windows Mobile beta version of its mobile VoIP, text and IM application.

EQO (pronounced "echo") is a free mobile application that lets users call anywhere in the world for rates from 1.2p per minute and also features "inexpensive" international text messages and free access to popular instant messaging services, including MSN, AIM, Yahoo, Google Talk, ICQ and Jabber.

This makes EQO available to the millions of Windows Mobile smartphones that have shipped worldwide (9 million in 2006 alone) on popular devices such as the HTC Touch, Samsung Blackjack, Motorola Q, Palm 750w and HP iPAQs.

By using EQO, the company claims that Windows Mobile smartphone users can now save up to 95% on international calls to landlines and mobile phones, and save up to 70% on international text messages.

In addition, calls and texts exchanged between EQO users are free. Once the EQO application is downloaded, users can automatically import all of their existing contacts into their EQO phonebook.

With EQO's presence feature, users are able to see which of their contacts are online and who is available for a call, to receive a text or have a chat using EQO's free IM feature.

"We've already had great feedback from early beta users on our Windows Mobile version", said EQO CEO Bill Tam. "In addition to the tighter integration to Windows Mobile calling features, our users really value the multi-chat IM capabilities of our client."
