[tcrhelpforsms]

I hadn't caught that you had responded in multiple locations.

If you see this as inventing problems, then it is clear you don't understand the use case.

Even ignoring the issue of carriers cracking down on SIM cloning, as you've said not all messages will be visible to all participants. So that makes it DOA.

You also clearly do not understand that the issues here are not all technical. Sure I could definitely bang out something using Twilio to send and recieve SMS, etc. Except Twilio requires you to comply with TCR. So again, that is DOA.

Sure if I was really adventurous I could buy tens (hundreds?) of thousands of dollars of telecom equipment and work on then have to negotiate peering with other providers. But you know, I figured I might ask on Hacker News as start.
