Hi Anndy, I use Skype to talk for free. But when I call to my girlfriend in UK I use Smartgroschen.

 

[Anndy]

why Smartgroschen? Is Smartgroschen really cheap and provide best call service?

 

[Elford]

Yes of-course, With Smartgroschen I get high audio quality. Just install and talk. 0,5 euro at start.
