Vopium works either Automatically or Manually depending on the operating system on your mobile.

Automatic

Vopium automatically detects when you make an international call and reroutes the call with Vopium. When you make a national call, Vopium routes your call via your mobile operator. Vopium also automatically detects when you are roaming to ensure the cheapest routing of the call. Vopium can read contact numbers from both the SIM-card memory and the mobile phone’s built-in memory. Mobile operating systems: Symbian, Windows Mobile, Blackberry (RIM).

Manual

To make a call with Vopium you first need to open Vopium on your mobile. You can then make a call either by entering it manually or from contacts. Before using the Contact function, you must save all your personal contacts to your mobile phone memory as Vopium does not have access to your SIM card.
Mobile operating systems: Java


Whether you have Vopium Automatic or Vopium Manual, you'll get the same savings and voice quality. However, to get the most convenient and seamless call experience, we recommend using a mobile phone allowing Vopium Automatic (supported by Symbian, Windows Mobile and Blackberry operating systems).
