there are many cards to call to ktm(mobile) and outside ktm. But the maximum is just 30 mins comparing to land line of kathmandu. Telenepal, tomatotel etc are offering good ones but not the best. I want to suggest to anyone(sajha member) to start this good business. But one thing, I have heard that Nepal police caught the persons involving in illegal connection in kathmandu. Will it affect to those call systems also. Expert's view please!!
