Is there a client-side way to tell if an SMS is sent via TCR?

If so, I’m guessing a good chunk of the US would pay for an app that silences the notifications and auto-responds STOP.

The TCR is a list that wireless carriers use to decide if they'll let a SMS message proceed or not.

I doubt the message itself indicates that it was weighed against the TCR list (it would require modifying the message).

Yeah, this isn't like e-mail headers where different hops in routing will insert additional information.
