These are relatively new restrictions - have been rolling out since this fall. https://support.twilio.com/hc/en-us/articles/1260800720410-W...

I've found sending from toll free numbers like 1-888 reduced filtering also. Only costs like a dollar or 2 a month extra.

That's not just anecdotal. The carriers do process short code and toll free traffic differently from regular 10DLC. You don't even need do register an a2p campaign for them.
