You're trying to figure out what it is incrementally, and I'm telling you Apple Messages for Business is ancient news and isn't fit for the purpose described: https://www.apple.com/ios/business-chat/ https://www.apple.com/ios/business-chat/ The "experiences" are not normal 1:1 iMessage conversations. You're joining an outreach channel, and only large corporations (that includes whoever does distribution for Billie Eilish) qualify. Proper consumer apps like: - tomo.ai - poke.com - fractal.space Are all building on services that give you an actual iMessage phone number, and those are what I'd like to see actually offer self-serve one day, just like SMS. You don't need "SMS For Business" to send an SMS.
