Internet communication service provider Skype this morning announced the availability of the popular service on three Sony Ericsson smartphones based on the Symbian platform. Users of Satio, Vivaz and Vivaz pro devices can now use Skype over WiFi or mobile data connection (that is: 3G, GPRS and EDGE).

If that’s your smartphone and you like free calls to your Skype friends on the go, head over to skype.com/m or visit the Sony Ericsson Play Now arena later this month.

Skype for Symbian will run on any Sony Ericsson smartphone using Symbian ^1, the latest version of the Symbian platform.

Features are listed here, but will be familiar to you if you’re a Skype user already (free Skype-to-Skype calling, cheaper SMS to phones abroad, instant messaging, file sharing, and more).
