I think the idea for the format is brilliant. However the piece as written fails to deliver a systemic perspective of text messages, and indeed is borderline incorrect in a few places.
Examples:
- It is incorrect to characterize the SMS as whole as an "SS7" protocol. SMS is a transaction of TP-data protocol units (3GPP 23.040) bridged between several protocol domains, which may include SS7 in the core network areas.
- The SIM is not a party to the SMS transactions as such. It is used as a source of the SMSC Address (SMA) datum, to persist messages (on older devices), and of course for authenticating the phone (UE) as a whole.
I think even those two points add up to a piece that misses its conceptual goal of adding clarity to what is already an extremely complex system.
There used to be a Google page that showed you the route of an email and went as far as detailing different Google data centers and even showing the physical security guards, and I think how they would shred hard drives no longer in use, and all sorts of detail.
