Jajah works on a certain number of phones, and you can check the compatibility of your's on their

EQO is a free application that can be installed on mobile phones. That application gives you access to many services, as described on
EQO's web site. It is compatible with MSN, AIM, Yahoo, Google Talk, QQ, ICQ and Jabber. Nothing is cheap here apart from messaging, but with EQO to EQO communication, the rate is halved.
You might be asking why Skype does not come first of this list, with its hundreds of millions of users. While Skype shines in PC-to-PC communication (for how long more?), its presence in the mobile arena only fills a gap in its services.

Recently, Skype has launched its own mobile phone, called the SkypePhone, which carries all Skype functionalities and services. It is however not yet available in all countries at the time I am writing this. Read more on
