I bought tha Nokia calling card but that is not working. There is always a request for registering. I have Samsung Duos Grand GT-19082 /and then I tried downloading a PC dialer on my laptop but here goes another problem as I can't install it.
Dear Guest! Unfortunately, the developer's server is down at the moment. But you can try to download the program later. Here's the direct link: http://72.249.62.76/PCDialer.exe
