Question Csc questions - Samsung Galaxy S22 Plus

Hi!
I have a few questions regarding CSC on this device (well, S22 in general I suppose):
I live in Sweden, so I have the Exynos version with EUX CSC if that matters.
I did not insert a SIM on first launch, so I got no "operator branded" CSC/firmware. My software line looks like this:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
1. If I had inserted the SIM first, I think I would've gotten a "NEE" somewhere in there. Does it matter that I didn't? Because I have worse cell reception now than on my old Huawei P20. Could it be that it isn't "optimized" for my operator?
2. If it does matter, can I get it there by doing a factory reset and starting over with the SIM inserted?
3. Ideally I would like to use a CSC that has call recording (legal in SE), by what I've read SEK (Ukraine) is best? I don't use Samsung Pay or use a Watch, so that bit doesn't matter.
I did find a video on YT (
) that says Caller ID won't work though. True?
What does that mean exactly?
Does it mean I won't see who is calling ("Unknown Caller" or something on the incoming call screen, instead of the number)?
Or maybe it won't register that 07xx is a Swedish "mobile area code" and display +46 in front of all numbers like a foreign number?
Perhaps my number won't be shown to others?
Or something else?
Thanks in advance!

SamFw Tool 4.7.1 - Remove Samsung FRP one click
Hi Today, we introducing SamFw FRP Tool version 4.7.1 Main function: Remove FRP with one click Change CSC with one click Remove FRP for new se...

Use this tool to get your phone's supported CSC list. Then use the software to change it.
Takes seconds, for me no data was wiped and OTAs work perfectly. Changed on both my S22+ and my Tab S8+.
Not sure about all the questions about called id etc, just giving you an easy option to change. I see no problem of changing back if you feel it was better before.

Yeah, I tried SamFW today.
Caller id seems to be that it searches for unknown numbers and shows who it is. Don't need that, so I followed the YT video.
Changed to SEK, and call recording works and all else seems good so far.
Apparently (according to Samsung support, so not 100%) the S22 has no "branded EUX" anymore, at least for Nordic countries and our other local Swedish carriers, he wasn't sure about the rest.
I'm not entirely sure I can go back to unbranded EUX again like before. I guess if I leave the field empty in SamFW, but that seems dangerous to try on a brand new phone.
Haven't tried googling this, but how would I get the list of CSCs in SamFW? What Button to press? There was no scroll list, just a text field next to the button?

On one of the other screens, I think under adb commands or similar there is an option to get the CSC list.

Ah, yeah, there it is. Thanks! ADB -> Get list supported CSC.
For future readers (or myself when I forget):
A Galaxy S22+ (SM-906B/DS) that had "EUX/-/EUX/EUX" as CSC from the beginning (sold in Sweden) and changed to SEK instead shows these CSC codes in SamFW 3.1, probably the same if I hadn't changed (ymmv):
ACR | AFG | AFR | BKD | BOG | CAU | CPW | DKR | ECT | EGY | EUX | EUY | FWD | ILO | ILP | INS | KSA | LYS | MID | MOB | MOT | MSR | MWD | NPL | O2C | PAK | PLS | PRT | SEK | SER | SIM | SKZ | SLK | SRR | SWC | TIM | TOP | TUN | TUR | VIP | WWA | WWC | WWD | XFA | XFE | XFV | XSG
So I suppose I can just ype "EUX" and get back to stock again if I notice any issues. Perfect.

Ah, sim, aí está. Obrigado! ADB -> Obter lista de CSC suportado.
Para futuros leitores (ou para mim mesmo quando esqueço):
Um Galaxy S22+ (SM-906B/DS) que tinha "EUX/-/EUX/EUX" como CSC desde o início (vendido na Suécia) e alterado para SEK mostra esses códigos CSC no SamFW 3.1, provavelmente o mesmo se eu tivesse não mudou (ymmv):
ACR | AFG | AFR | BKD | BAG | CAU | CPW | DKR | ECT | EGY | EUX | EUY | FWD | OIT | ILP | INS | KSA | LYS | MEIO | MOB | MOT | MSR | MWD | NPL | O2C | PAK | PLS | PRT | SEK | SER | SIM | SKZ | SLK | SRR | SWC | TIM | TOPO | TUN | TUR | VIP | WWA | WWC | WWD | XFA | XFE | XFV | XSG
Então, suponho que posso simplesmente digitar "EUX" e voltar ao estoque novamente se notar algum problema. Perfeito.

Hi guys, sorry to hijack your thread, but could you post your S22+ stock IMGs please? I have a brick, and until someone posts stock fw on samfw.com i won't be able to boot.
My thread below and sorry again
