The SIM used tells it what networks to look for.
This whole things just a placebo.
That is not the normal course of events, but 3GPP makes allowance for the SIM and "default networks" to be read if required.
The correct sequence is that the "available networks" data to be read firstly from the "last network used" memory location, then the SIM, and finally from the "default networks", which is what this topic is about.
If there is a "bug" in the Baseband, it may well be reading always from the "default networks" list, rather than the "last used" or SIM network list.
