Vopium launches their mobile VoIP service in the US

Vopium launched their mobile VoIP service in the US recently, offering a lower cost option for international calls from cell phones. Vopium consists of a free software app for your mobile handset that routes your int’l calls over their network.

Vopium is available for over 500 GSM handsets from over 20 hardware vendors and they impressively have very detailed howto guides with screenshots on their website.

As far as costs go, they claim an up to 90% discount on typical international calls from cell phones. And if your phone has WiFi, you can make the call for free. As an incentive to new users, they offer 30 free minutes of talk time. You can even send text messages overseas as well.
