Now iPhone users can make FREE calls to Vopium users, Skype users and Gtalk users also outside Wi-Fi, using the 3G data network. You also avoid the local charge and the call set-up charge to your operator. Instead you use your data plan.
3G data/VoIP calls are disabled as default, but can be enabled from settings in the new Vopium app.
NB! We recommend that you only enable 3G data calls if you have a flat rate data subscription. We also strongly recommend that you disable 3G VoIP/data calls when travelling to avoid expensive data roaming charges.
3G VoIP/data calls are already supported on Nokia Symbian and Windows Mobile.
