Vopium is a free software program that uses mobile VoIP and Wi-Fi technology to reduce the cost of international phone calls on mobile whilst also maintaining excellent call quality. Free and easy to download, Vopium integrates directly with the address book on the phone, automatically re-routing all international calls via the least expensive method available. In addition to heavily discounted international calls, Vopium users can also slash the costs of sending text messages (SMS) abroad as each message only costs 9p.

It’s pretty much by the book in terms of implementation – address book sync, WiFi calls but what we like is that it makes use of a system that determines the cheapest reroute from an International call.
