OK,
So basically what this is saying is that a GSM module is a critical
component. If you remove that GSM module (they look like this:

probably isn't any way to activate the feature in the CPU (to disable it or
remotely control it). It doesn't sound like it communicates via TCP/IP at
all. Rather it does do something similar with SMS messages.
Again- nothing is saying that the technology doesn't also enable a hidden
feature such that the same thing can be done via TCP/IP though. Which goes
back to the concern I'd have over what exactly is in the firmware.
