JAJAH is a VoIP (Voice of IP) service which allows you to make free or cheaper calls all over the world straight from your normal phone.

Usually JAJAH is used via a web-browser and the number is called by typing the number into a web interface and initiate the call. You’re then called back by JAJAH and forwarded to the number you dialed.

The really amazing thing and the reason why I write about here is, that JAJAH also provides a plugin for mobile phones and enables you to use the service without the use of a PC.
The plugin runs in the background and when you call a number outside your homezone the plugin forwards the call to JAJAH and you will pay the JAJAH fees, not the more expensive ones from your provider.

The best of this is, it works really great and helps you to save a lot of money! But take care if you’re outside your homezone. The plugin opens a webconnection and this means that you have to pay for roaming. This could end in a even higher fee.
