I"m trying to figure this out, sorry if it's too basic of a question.
I have iPhone app with several hundred users. While they're interacting with my app, I need the ability to send them several SMS messages (max 10). Say 300 users, using the app once a week, with 10 SMS per use:
300*4*10 * .0075 = $90
There is also a $1 per month phone fee. Is that per phone of my users, or the single Twilio number that I am sending texts from?
I'm hoping it's not per user number, which would make my monthly $390.
I've reached out to Twilio, but still waiting a response.
