Calls from landlines and mobiles in Oman to India are quite expensive. It costs around 240 baisa (around Rs. 25) per minute during peak hours and 220 baisa (around Rs.23) during off peak hours from a landline, and 20-30 baisa less via mobiles. The other way around –– from India to Oman –– is a mere Rs. 12 per minute. If you are not careful enough, then phone bills can surely burn a hole in your wallet at the end of the month.
