Nowadays BSNL's International calling card and various mobile co's ISD pack is easy to use and cheaper than any skype.I used to go sify and make ISD calls to Singapore /HK institutions ( say minimum 5-15 mins duration) @ Rs 3 /min. Not any more.Just received this promo sms in my Uninor data GPRS sim "Full ISD talktime !
