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

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.
