STIR/SHAKEN only affects voice calls. It has nothing to do with SMS.
As several other people have said, if you're sending safety critical SMS messages, use
a real SMS service, not a carrier's courtesy low volume e-mail gateway.
SMS services are not free, but they are not expensive, typically about 1/2 cent per message.
