Hey, I did my research on starting a calling card business in the us, it his hard.. but can you give me a insight on the pinless calling system it just started growing and I would like to get in.. Any advice. Also I think digicel is one of fastest growing tech companys they just started selling cards in the usa (new york) and taking over.

Their website shows that they are not is the US. I don't think the calling card business would sustain a good profit margin since the competitors already have flooded the market in the US. Never heard of Digicel before but it's not surprising.
