Vopium allows you to save up to 90% when making international calls or sending SMS from your Smartphone in your home country and this without changing your current operator or SIM-card. You pay your mobile provider for a local call and Vopium for the international call. With Vopium WiFi you can even make 100% free calls and avoid roaming charges when abroad.

It only takes a few minutes to register at Vopium. Following the registration, you download the Vopium software, which takes the same time as downloading a new ring tone. Install the Vopium software, and you are ready to "Reach the World for Less"
