Trueroots are back with the offer of double your talk time and this time its on normal recharge also and not just auto recharge. You get credit in your accounts in seconds of payment.
There calling rates to India are 6.9 cents, So with double recharge it should work out to 6.9/2 = 3.45 cents/minutes which I believe is cheaper than any calling card. They have excellent call quality and good customer service.
