This thread is only for people who are calling India(cell phones and landlines) quite frequently.
Keku(formerly known as stanacard) is offering unlimited India calling only @14.99/30 days.(No tax)
I have been using them for quite a while now and kind of like them, specially with this offer it looks awesome.
Also, they double your amount(upto $10) when you create the account for the first time and have it credited with atleast $10.
Here is the link to their website to get more info:
