That too if net is too congested, you have to redial. So finally it also comes to Rs.12 to Rs.15 !!!.
Even from AIRTEL PREPAID (all zones) mobile in India, calls to GULF countries are at Rs.9.99 per minute + 12.24% service charge (on recharges) = Rs.11.212776 per minute which comes barely Rs.2 more to Rs.2 lesser than phonewala.com and other providers's rates.
