Hi Guys...

Calling card problem is now over.... if u like good calling card service and want to have double your minutes use STANA CARD.

Process of using STANA CARD

You open an account by going to www.stanacard.com.
If you enter your referral code 171728 on signup we will double any credit you buy.

If you sign up and make your initial purchase of $5, you will actually get $10.
If you sign up and make your initial purchase $10, you actually get $20.

Believe, I tried this and able to double my minutes....

Enjoy....
