Mobile VOIP is currently supported on i Phone, Android, Nokia Symbian, Windows Phone, Windows 8/RT and Black Berry.
Simply download the free Mobile VOIP app from your APP market and register with one of the supported Voip brands.
You can turn notifications off to ignore folks, like that one friend who won't stop playing Singed even though they feed hard as him.
The app lets you see your friends list, add new pals, and chat one-on-one at launch, but expect it to add features over time, evolving as League of Legends does.
Saving on your cell phone calling plan was never this easy!
