Vopium is the first VoIP service provider to offer a Wi-Fi calling app through BlackBerry App World. Rebtel offers a similar service, but with it you need to use your monthly minutes, which can be a costly while travelling. And logically, the Vopium app offers least-cost routing to both mobile and landline numbers whenever you’re connected to Wi-Fi.
The Vopium app apparently makes it easy for users to know if they are connected to and placing calls via Wi-Fi. Vopium designed the app to minimize battery consumption, so users can make frequent Wi-Fi calls and still have battery life that lasts at least a full day. This makes Wi-Fi calling a viable replacement for office desk phones and home phones.
Vopium claims more than 1 million users in 52 countries and is listed on the NYSE Euronext Paris Exchange. The app is available now in beta version for BlackBerry smartphones running OS 6 or later. The app is available directly from Vopium and from BlackBerry App World.
