Excellent article, however, there's no mention here anywhere about where the SMPP, or UCP protocols, or even the CIMD protocol come into play. I would have liked to know if the handsets actually deal with these protocols, or if those are just for communication between content providers and Telecom providers.

All of the protocols you mention are used only for communication with an SMSC at the application level, for example an application connecting to the SMSC via a TCP transport.
Handsets use some random ETSI TS spec (part of the GSM specifications) to send SMS over the air.

Thanks for shining some light on that.
