I have found a really good card: almost like himtel, clear voice, no connection charge, no maintaienance cost, 1 min rounding, your phone no display in the receiver phone, you can directly call without pin, and a lot of good things. 36 mins for $ 10. First you have to buy $ 15 and if you use the referral code, you will get mins for $ 5 free. CLICKHERE. If you use following referral code, you will get calling time equivalent of $5 as a bonus. Your referral code is: 4479054
