Absolutely, testing different price points. I, however, think that people are likely to pay a fee closer to normal call rate whether local or international. Consulting calls could be a little bit costly. Just a null hypothesis.
Yes. My first fee rate was 0/min. A friend @1304 could pass the opportunity 😂😂😂😂... now at 0.99/min. I haven't received a call yet. My guess is that users are happy to pay a fee the same as ordinary calls. It's different for consulting calls though.
Finally deleting @Netflix. It is paradoxical to watch a Netflix production on American TV before it's released on Netflix. Guys, CHOOSE between paid up subscribers or American TV audience.
