I might have to say that nepalisite.com people are the best so far in service and everything. I used to use SDI also. Then swithced to nepalisite.com Yes phone cards are a hassle. Every cards are like that, but one good thing about nepalisite was that when I had any doubts or problems then they took care of me good. i m not just speaking for myself. Try it yourself and see how they treat you. They will tell you everything about cards you wanna know. Can you imagine that they even didn't force me to buy. They were telling the facts such as rounding issues. hidden charges actual minutes connections loss of minutes... Seems like lots of issues involved in phone cards, but hey we are nepalese and we complain a lot--but guess what they are ready to answer those. thumbs up to those team at nepalisite.com and besides... if you have problem speak up--and use websites run by nepalese and call them if you have problem in trusting. And see how it will be to you. I m not speaking about only nepalisite only. Call other sites customer service also and choose. And besides phone card there is model of the month also haa..This time he looks like a kid. Good Luck...
