For past one week I have been calling Nepal daily just to see how good this card is. I even called my friends in Australia, United kingdom, India and Canada. And every country I tried had same good quality. I think I am very satisfied with this one. I used to use "callontime", "himtel", and "Procard" but I guess this www.tel3call.com is different. Its hard to find card like this to make an international call. I am gonna stick with this card. Other people who tried this card can you post your experience?
