i use powerdial from powenet-global.org. there r other plans as well. the connection is not good all the time but it's acceptable. it is a long distance calling plan not a calling card. there's no monthly fee, u get charged as u use it and it's 20 cents/min for ktm. it takes 1-2 weeks to get an a/c w/ em. one thing that i like the most from this plan is 6 seconds billing increment.
