Last year EQO Communications launched the EQO service, which extends these VoIP service back to the mobile phone, and in addition to offering free IM (instant messaging) service to popular services like: ICQ, MSN Messenger, Google Talk and Jabber.
You may ask, why do you want to have VoIP on a mobile phone? Why does one just use the mobile phone itself to make the call required. The answer is cost. In most cases, there is a discount of about 95%. Like other VoIP providers, EQO offer free calls to other registered EQO users.
Although it offers this service to 29 countries it does not yet offer its service to Asia and more specifically Hong Kong. I am calling everyone in Asia to help convince EQO to begin offering their service in Hong Kong and rest of Asia. Please go to EQO's country suggestion page to add your respective countries to their list of desired countries.
