Hi, this is my first post. And im new on this teme of the Multi CSC roms.
I have a question, I get a ROM from SamMobile of my carrier Telcel in Mexico (TCE). I understand that the rom is multi csc, but when I flashed it all the bloatware (that in this case i need, VoLTE is only in my carrier) is from Claro (CHL), and I need it from Telcel. I sent a mail to SamMobile explaining this but they only answered me that the room its ok, the rom is multi CSC.
The CSC version that the system shows me is CHL/CHL/TCE, and I need TCE/TCE/TCE.
Anyone knows what I should do?
From my experience changing firmwares to enable volte, to fully restore csc it's flashing the firmware TCE, download from samfirm app on computer then factory reset from the firmware you have, flash TCE firmware with Odin and this it's the trick you need to have another carrier sim(no telcel) before flash the firmware TCE, wait for boot(don't put an account) when you are on the home screen turn off then enter recovery and factory reset and reboot, here when you swap the Sims, put the telcel sim on it and wait to fully boot and when you see the welcome screen you see a message that say the sim card it's different and need to reset, accept and wait for boot go to settings and check csc and now would be TCE\TCE\TCE

Do you really managed to change CSC from one operator (either one) to multi CSC ? And if you do so, can you make a guide for us?

In my quest for fully change the csc without flash twrp and root to lose Knox warranty I ended with some smart guy that say the first two can be changed with flashing firmwares and the last one can only changed with root for that reason if you flash a different firmware region the two changed with the default csc on the multi csc and the last one stay same for example in this case MXO/MXO/TCE and the only way to return all the same it's using other carrier sim card temp until you flash the original firmware and then factory reset and when reboots swap sims putting the original carrier sim card in this particular case telcel

Thank you for your answer! But, let me see if I understood.
1- Put a sim from another carrier.
2- Factory Reset.
3- Flash the phone.
4- Turn on, and configure it.
5- Factory reset (again?)
6- Then put the Telcel SIM, before it starts completely
7- And finaly, in the "Welcome" screen, when the phone shows the message of the sim changed, perform another factory reset.
Let me know if I am right,
Right now I don't have another sim, i think that its rare that someone has another carrier But when I have it ill tell you what happenned

Yes basically that's the steps but in the step 5 it's important that you factory reset from recovery

Hi,
At step 1 is any SIM or original CSC SIM?

Depends what do you want to do.
In this particular case try to get original CSC TCE/TCE/TCE
He has CH/CH/TCE
If you wanna recover original CSC you need to have another carrier sim on step 1 and when you flash the original firmware go to recovery amd factory reset from there and when you put reboot in the process of boot you swap sims, put the original carrier, firmware sim

Do you know if the phone must be unlocked? I tried to do it but when I put the other sim, asks me for the carrier unlock code. The phone doesn't show me the message of the sim changed.
I've been some research and I found that Claro is Telcel in the rest of America Latina. Maybe its the reason that shows me Claro.
I tried the CSC secret code *#272*IMEI# and nothing happens, how i know if a ROM would let me do this?

For that only flashing another firmware if you are from Mexico could you install MXO firmware it's the generic Mexican clean version and that you get MXO/MXO/TCE
The last one remains TCE this only can be change with root.

Actually I have the MXO/MXO/TCE, i've tried with the TCE rom, but still showing Claro. And these two roms doesn't allow the csc secret code. Don't you know what rom allows the csc secret code? I don't wanna try multiple roms from sammobile the download speeds are frustrating.

Try download from samfirm it's more fastest download the full firmware it's pc exe.
Do you try the step mention above? With other sim factory reset from recovery and swap sims, when phone boots tells you the sim change and need to reset and then you get TCE/TCE/TCE

Wow thank you! Im downloading it right now at 2.2 mb/s, compared with 100 kb/s of sammobile.
I tried anything and nothing works, I think that the unique solution is try with another OWA roms, I don't know if Telcel and Claro SIM's have similar identifiers and thats why returns me to Claro. Don't you know if there are roms with the csc menu activated?

Nope, do you think that the carrier lock relates with the problem?
Which sim carrier did you try?
Could I have problems if I try ATT or Movistar roms?

My phone was originally from att but I unlocked it and now use it on telcel and I want to use VoLTE with telcel. I would like to try the att or movistar firmwares but the problem is that (for what I've read) since the last att update was from like March the bootloader is older (v1) compared to telcel or MXO (v2) so you can't downgrade.
What carrier are you using? And what do you want it to be?

As far I know to get VoLTE on telcel you need to buy phone directly with them, because uses the imei to enable that function

Yes, I thought so too, but the thing is I went to Telcel and asked and the told me that my phone SHOULD have VoLTE but I think that may be associated with my phone number, (since I've had that number for a long time), and not with the IMEI
I have a galaxy s9 that im using on Bluegrass.
With the bluegrass sim in the phone when it does the autopreconfig reboot. It doesn't load the carrier settings properly. Example: I can't select global network type and I can't select the proper apn. Only verizion type apns with no ability to save a new one.
I had the csc changed to verizion which pretty much is the same as bluegrass.
Now I have vzw/vzw/xaa
So at my current delima only way I can use the phone is with the verizion csc and then disable autopreconfig before inserting the bluegrass sim. This allows for the global network state and I have full network usability. Volte don't work and some other things.
The same sim in my tmobile galaxy s8+ brings up LRA/LRA/TMB and it works perfectly even volte.
On the galaxy s9 if I do t use the verizion csc and disable auto preconfig I get all kinds of trouble. It will some what connect to the network. But the name listed is 'Roaming indicator off" as my connected network.
The dialer code *#272*imei# does not work for me on the galaxy s9 either. Does this mean it's a non multi csc? I mean it shouldn't be...
Would flashing u1 then back to u help? I have seen thst somewhere to fix some issues. Is thst still relevant?

the apn thing is a vzw firmware issue. Flash U1 on it and im sure itll be better. Also, if you flash the HOME_CSC it wont factory reset it

Just a real quick question before i return the phone tomorrow.
On the g981u1 (purchased from google through Fi), same as everywhere else, has the sim manager disabled, bootloader not unlockable.
From all the searching i did today, which was horrible, i just wanted to verify in a last ditch effort before sending it back.
The only way i found to enable esim is to modify the features.xml (from sounds of it). However to do so you need root, and of course it appears root requires unlocked bootloader(unless i missed something somewhere)
I have been unable to find a way to unlock bootloader(am i wrong?)
I havent found root (without unlocked bootloader)
Edit- nvm i found what i was looking for

So far, no go on the esim. I did get unlocked etc, but it seems something else is keeping the esim inactive. I almost need a snapdragon with esim working (from another country) to compare to

Snapdragon variants aren't eSIM enabled, only Exynos devices.
I remember seeing the option enabled when you flash the Exynos magisk module on a Snapdragon device. It also gave me call recorder.

CSC change does not appear to work on snapdragon, i already tried it.
HOWEVER, editing Build.prop in vendor did enable sim manager for me, however status is showing esim imei as unknown (yes my box has 2 imei) and the add gets stuck

I am rooted/unlocked
In vendor\build.prop i found "persist.radio.multisim.config=ss" which is single sim. dsds would be for dual sim. Phone would not let me modify or replace the build.prop.
With the recommendation from Orphee i installed this package in my magisk
https://forum.xda-developers.com/apps/magisk/module-magiskhide-props-config-t3789228
From there it let me change that line to dsds, and thus here we are. I am unsure if dsds should be a different line for esim, or if something else is needed to "start" the esim.
Are both modules enabled ? CSC and Props config
And is there 2 IMEI written in phone About screen ? Not only the box.

Currently the IMEI for esim shows unknown, so it IS possible i broke that during UL/root or something, but i feel more inclined to believe it is just not enabled. On stock rom it only showed the normal IMEI
I have tried both yes
Then you must fix or find how to have the IMEI number shown in the phone menu.
Esim registration will not work until you have the IMEI number shown.

Download Google dialer and then enter *#*#467#*#" and there's some esim related toggles available now.
You can enable RCS here too if you know what you're doing.

Hi, i have a stock firmware AUT (switzerland) installed, but if i insert swisscom (SWC) sim, does it automatically change AUT to SWC? Thanks
Using SIM of another country does change CSC, if it didn't, simply go to recovery mode and it shall apply the new CSC code.
However, it's not guaranteed which CSC will it convert to, as there were reports of a different applied CSC code than the country's one.
I found patched Odin 3B.
You can reflash rom for any possible region and 3 fields in CSC will be changed. Last one no.

Well, i dont want to change csc code, but if i insert the sim card of swisscom (still switzerland) does it still change csc code? (Without wiping) Or does it stay in AUT?

It won't wipe anything unless you manually change CSC using dial code or any other way to trigger the change.
Using another country's SIM does change CSC (after a reboot). You sound like you don't want to change CSC .. right?

The Operating System has a list of every SIM carrier out there. The SIM itself does tell the phone which country it belongs to.
Using different carriers on the se device, in the same country does not trigger CSC change. The trigger only starts when another country is reported to the phone.
If you want to skip CSC change, there may be two ways, either root your device, or disable the system apps responsible for it.

You receive a brand new phone >> The phone asks you to insert the SIM card and reboot >> You follow >> The phone applies the new CSC code respectively for your country >> You simply use your phone as a normal citizen would in that country.
You return back to your country >> You insert your country's SIM >> Phone asks you to reboot >> Your original CSC is back.

Wait.... i inserted a japanese sim which has no contract and the csc didnt change
I bought a Canadian variant Samsung Galaxy S20 (Snapdragon) yesterday, and knew that the SIM reader slot was faulty and needed to be replaced. I had assumed that I could just use eSIM, but didn't realize that the Canadian variants have it blocked.
Any advice on how to enable it? Can I maybe flash international firmware onto it to have the SIM card manager and enabling of eSIM, and if so, which one and how? Using Odin? Or a modified Odin? Do I need a working SIM reader?
Or maybe I change the CSC? If so, any instructions on how to do it with my variant?
Or do I need to root? If so, any instructions on how to unlock the bootloader (I don't have the OEM unlock option in Developer Options) if I am on One UI version 4.1? Or do I need to downgrade? If so, how do I downgrade?
I really don't want to have to tear this phone apart and resolder on a new SIM reader slot. It's a really great phone and the nicest one I've owned.
I'm not sure where to start.

i will
I read that if the W model is flashed with the U1 firmware, Samsung Pay can no longer have Canadian credit cards added. Can someone verify? OneUI 5.1 is being tested on the S20. We can only hope Samsung enables eSIM for that release.
W model has 13 release now. Does it still not support esim?
I was on the U1 model Android 12 in Dec 2022 (With esim enabled) and updated to the W model Android 13 firmware figuring it should have esim enabled however it did not.
I used odin to switch to the Android 13 U1 firmware but it did not enable esim (I used the home_csc). I flashed the older U1 Android 12 firmware which did enable esim again but I had to factory reset the phone due to a boot loop.
After reseting and doing an OTA update to Android 13 the esim stayed enabled and I restored a backup using smart switch for my apps and settings.

So in summary, to get eSIM in A13 U1, first odin install A12 U1, and then OTA to A13? The A13 U1 was uploaded yesterday ( link ).

It may work if you use csc instead of home_csc which would reset the phone straight out. I used home_csc which kept my Canadian firmware settings and likely csc

Does Samsung Pay work with Canadian credit cards in your A13 U1? That's the only requirement holding me back from converting. Samsung Pay+Google Wallet cover 90% of the places I regularly shop at.

I only use google wallet so I never tried samsung pay before. I installed samsung wallet and seems it wants a us zip code.
Ok guys so i bought Samsung Galaxy S22+ in Korea. I am from Europe. Reason why i bought phone in Korea was it was like 20% cheaper then in EU + it have Snapdragon instead Exynos.
But as i came back home i was in for a suprise, coz i tried to set up dual sim for the phone, but then i realized i cant do it. SIM card tray where u put physical SIM cards have only 1 SLOT, 2nd slot that was supposed to be on the back side is slighty modified so SIM card cant fit in, also there is no writing SIM2 like its written on fron (SIM1).
Also phone doesnt have support for eSIM, i cant open SIM manager or anything related to SIM cards in settings of my phone.
Dual SIM is important for me coz i use 1 SIM for SMS and phonecalls, its my number, and 2nd SIM is for internet. We are able to buy internet SIM here that have 60GB of data per month and its super cheap, like 7 EURO, so running dual SIM is super cheap version. If i buy internet via my regular phone providers where i can use phonecalls and SMS combined, it cost like 3x more.
SO yeah, i mean i could go for more expensive version and just have 1 SIM but its stupid coz 1 of reasons was i bought that phone is to run it DUAL SIM, i have also my old Huawei P30 pro working just fine, and now i feel dumb for buying another new phone that was meant to replace my old and its not working 100% correctly...
Can i modify my phone to make it work? Install EU version of Android or something? I would rly like to make it work, although even if i make it work i am not sure if my Internet/Phone service provider support eSIM so i swap this main physical sim with eSIM and then use internet one as physical. But ill deal with this later. I just wanna try enable eSIM first if its possible and have dual sim support in my settings.
Any help is very appreciated!
Best regards!
