Ram Prasad, after trying all sorts of phone cards cards, I've settled with Himtel for the last few months. Their Kathmandu Connect card for $5 has always given me half an hour of talk time. But it only works inside Kathmandu. For calls outside Kathmandu, I've used their Clean Card, which costs $10 and gives 26 minutes of talk time. Btw, I'm not related to Himtel but have been impressed by their curteous and prompt customer service. TitoMitho.
