Hey since you mentioned you ear sleep and breathe this stuff I thought I'd ask a question.

Do you know how easy/hard it is to start a "international calling card" service?

I see lots of random ones popping up every day and they mostly look unprofessional so they remind me of email/web-hosting resellers.

I was wondering if reselling "international calling card" is a thing? or do you actually need your own infrastructure?

I was hoping that I can resell these services and make some passive income that way (I can directly market to low-competition markets in my home country).

International calling card services are cheap to implement. The main issue people run into is fraud. I think that after DNS reflection, SIP attacks have to be one of the most common assaults. In addition, I've never seen a prepaid calling company that didn't get defrauded, you just build the losses into your margins.

The typical way this is is done is to get a carrier route to a specific country and then arbitrage between that rate and the expected rate from say AT&T. There's usually a lot of margin when you compare it to AT&T costs, but you'll find the business is ultra competitive. We call voice the race to zero.
