I appreciate the question. You've laid out a good segue for me.
On the telephony side, we've done things such as universal call blocking, as I mentioned, 123-456-7890, but also STIR/SHAKEN, which is really that call verification system. Is it your bank calling? It can at least give you an X or a “potentially fraud”, or it can let you know if you should trust that phone call.
On the SMS text message side, the timing of your question is very good, because last year we introduced a framework to allow TSPs to block emails and SMS text messages that they know to be fraudulent. I'll be honest; I'm the policy guy, but there are all kinds of technicalities behind it where they can determine whether an SMS text message is valid or whether an email has a particular attachment you shouldn't click on, etc.
We're about to release a decision in the coming weeks that will actually enhance that framework even more and allow the telcos to do more, in that they can stop those text messages from hitting your phone.
