Hi I used phone cards from isellphonecards.com website. I got a card for $5 which let me talk for 90 minutes. It does not have any connection fees either. I think it is called Crazy Crazy. The connection is quite clear. Only thing is you need to have long distance access as they dont have any 800 number. So you need to use the local access number which might be from a different state. Cause i am from Arizona and i need to dial LA code. But it is quite good as i call Nepal several times with $5. Hope it was helpful.
