Technology:
The core of Vopium`s product is a software program that is installed on a mobile phone or Smartphone from all major producers such as Nokia, Sony-Ericsson, Samsung, HTC and Motorola. It takes less than a minute to download and install the program, which works on most of the newer phones. The program runs in the background and when you are making an international call you will be asked if you wish to use Vopium.

If you choose to make the call through Vopium you will pay the domestic tariff along with a tariff for the call abroad, which is up to 90 % cheaper than what the regular mobile operator are charging. This is because Vopium automatically transfers the call to a much cheaper line of the same quality. Talk time can be purchased on the internet and can be paid with all major credit card.
