In past 1 year or so, we have learned a lot about cheap calling card, VOIP, fraud cards, Fraud Company etc. There are few major things that you need to think before you go for cheap calling cards 1) Do you just want cheap calling card? Means no customer service after you buy. - Most of the time either you buy online or from retailer, once you walked out from there it's not the retailer's responsibility anymore. There will always be a customer support # back of the card but those are completely depends upon how lucky you are. 2) When you said cheap card are you looking for just face value? Are you aware of various hidden charges like connection fee, weekly maintenance fee etc. 3) Do you really care about high quality voice transmmision? My experience tells me just stay with Nepali enterprenuers. There are many these days. Atleast their customer service is lot better than others unkown .coms and they understand your problem very well. Whenever I get my minute lost without talking they add it etc. Good Luck.
