go to
http://evaphone.com
it offers calls from pc to mobile but limitation is that u can only call 20 sec in each day.
but i am giving u a new trick by which u can call unlimited.
1. open http://evaphone.com
2.and enter ur number and press call
3.but when ur call complete dont press end call
4.rather disconnect the web page and then connect again.
