Owners of Nokia's new N and E series of mobile phones can download a software plug-in that allows them to make and receive VoIP calls from their handsets via WiFi and 3G.
Engin's product also comes in the form of a software package downloadable to Nokia phones, while Skype offers free Skype minutes to other Skype phones through the 3 telecommunications carrier. A pre-paid service from GoTalk is also in the works.
Called ‘MyNetFone On-the-Go', the software client doesn't interfere with the mobile's regular coverage – users can still make normal mobile calls independent of their MyNetFone plan.
Besides allowing cheaper call rates while out and about, one of On-the-Go's biggest calling cards is the ability for users to make phones calls while overseas which are free of roaming charges.
"We are very excited in launching this new generation of mobile service," said MyNetFone managing director, Andy Fung.
