Postmaster @ vtext.com (or what are best practice to send SMS these days)

Wed Apr 16 23:37:17 UTC 2008

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.
