Is it possible to use VoIP over 3G on the N73?
VoIP Client?
I think it is, with Gizmo.
Maybe Symmy?
Would appear you can only use Gizmo with their own service?
And Symmy website is down 😞
Edit: The N73 Internet Edition has a VoIP client doesn't it? Is flashing the phone an option?
There is wide rande of VoIP and SIP VoIP clients for N73 phone. List here.
i use fring as the voip client on my n73, then use 'voipstunt' in fring as the voip gateway. i can call for free to around 50 countries using voipstunt in fring.
skype, msn and googletalk can also be used in fring.
Does Fring work with VoipDiscount?
Does voipstunt.com supported by built-in N95 VoIP client?
I think all of betamax services supported by Fring.
I use Morange on my N73 over 3G. Its new features include VOIP (MoTalk) and international SMS. Pretty simple and cheap. Can get it from their webpage.
