Piecing together the information I've learned over time, is it possible that
VeriSign handles some of that for Verizon?

Verizon at least, uses SS7 signaling to deliver on-network SMS. This
means they can provide delivery confirmation with their SMSes. I am not
aware of another US network that does this or interacts with Verizon
over SS7 for SMS exchange.
So, if you are using a phone's SMS capability on the same network (e.g.
Verizon) and it has delivery confirmation you might be very happy.
