Evaphone is completely online service so you do not need to download any program to make free international calls. I tested this service and it is working fine. You can make 2 free calls everyday. Free calls are ad supported, so a small ad will play before you can connect to a mobile number.

It is completely online so it does need required any setup or any download and install. You can make free call almost in any cyber café.
