Still using an old Nokia 2720 Fold phone, running KaiOS.
I read that KaiOS was based on Mozilla FireOS.

I noticed that one of the SIM card momentarily was
labelled "Locked SIM", before the label changed to
the name of the mobile network operator.

Could a cell phone know whether a SIM card was
locked? I supposed the operator would only
deny a suspicious SIM card of services.

The Nokia phone doesn't support e-SIM as far
as I know. It's a really out-dated cellphone.

Puzzling...

The SIM card also provide software and functions to the phone, I
understand. ISPs use this.

There are "e-SIM cards" that add eSIM functionality to the phone. Read comp.mobile.android group.

Aren't ALL SIM cards 'e' .... so therefore all "e-SIM" cards??

Seems to me if phones have two SIM cards in them, one should be for
Phone functionality (with room for increased functionality, maybe, and
the second be for MY Functionality (Phone numbers, SMS, Photo's, etc.(My STUFF))

No.

e-SIM are not cards, they are files.

No. One card is for the first ISP, the second is for the second ISP.
Like, one for your personal phone number, and the second for the work
phone number. Or for a number at your travel destination .

You are talking of memory cards.

Your Honors/Honours:

You will need to check the software and hardware that
use the SIM ID number or maybe just the registered
cellphone number!

Like a firewall and any computer storage, the SIM
ID in a physical SIM will more or less be changed
into a temporary memory address that can be
tampered with.

It's not like sending a physical paper with ink
sealed with a kiss(?) and wax in a physical
envelope. Computer networking is virtual, just
signals and switches.
