The service is very straight forward to use. On the web page you enter two telephone numbers - yours and the person you are calling, click call and that's it! You can also trigger a phone call by sending a premium sms - we call you back and connect you to the number in the sms message. It makes VoIP more user friendly - without the need of microphones, headsets or tieing the user to the pc.
The service is quite revolutionary when it comes to charging - a flat fee is charged per call, with very low rates. Basically it is assumed that statistically not every call will be max duration.
Great work by the GG VoIP team!
