He just uses Twilio, they handle everything, he just calls some APIs and takes a 257% markup for phone calls. Anyone can sign up, usually at most you'll need a local address.
1. your privacy policy
> Third Parties
> - Twilio: Calls, SMS, phone numbers
2. your pricing and twilio's pricing
Twilio: $0.0140 / min
You: $0.05 / min
(0.05 - 0.0140) / 0.0140 * 100 = 257%
our markup is mere 30% not 257%.
thanks for the checks up tho :)
