IMHO the bigger problem with group chat over SMS is that some networks (looking at you AT&T) limit the number of participants in a group SMS chat to ten. If you try to send a message to more than ten people it sends it ten of them, silently ignoring the rest, leading to weird fractured SMS group chats.

you are right about the limit of ten. but it may be part of the sms specification itself. at least that’s what i remember from looking it up a couple years ago.

Nothing stops the phone from sending multiple sms, its the implementations fault
