I set up my Z Flip3, purchased directly from Samsung in Canada, yesterday. I inserted the Koodo SIM card from my previous Note 10+ into the Flip3, then used Smart Switch to move apps, settings and data over. Everything seemed to work fine, but I'm curious about the information shown in "Service provider software version" in "Software information." There are 4 CSC codes as follows: KDO/KDO/XAC/KDO.
Can anyone explain what the 4 codes mean? It makes me worry that the phone now looks like it's locked to Koodo, which it certainly shouldn't be. I bought it from Samsung.
Thanks -- Pauline
So what were the CSC codes before the SIM was inserted?
I would recommend that you do not restore any application backups, but install and set up each application manually, to avoid the problem of transferring to the new device the settings that were in the original device, this may also apply to system application settings that you don't even know about. and CSC code settings.
I would now try Hard Reset without a SIM card (factory reset). And then check the CSC codes.

Alright, so, last weekend I got a new Samsung Galaxy J7 with Android 6.0.1. The first thing I did was rooting it. It was all going fine until I accidentally unticked the "OEM Unlock" option on Developer Mode, so when I rebooted it, it had an FRP Lock.
I used a Latin American firmware to be able to boot it again. At boot, there was this "entel" logo, and this seemed to have changed my IMEI because my phone always said Network Unavailable. I didn't check the IMEI prior to rooting it, but I noticed the printed one and the one shown on the phone weren't the same... but this isn't the real problem.
Originally, the phone was unlocked (no specific carrier/operator holding it), and I somehow "fixed" the Network Unavailable thing by erasing the efs folder on root... well, it was a longer process than just deleting it, I backed up the folder and copied some files (some might know what I'm talking about). After that, the IMEI was the same than the printed one, but, my phone is now network SIM locked!
I have to input a code to unlock it. I did some googling and apparently only the carrier can give it to you, so I tried 3 different carrier SIM cards to see if any of them were the carrier's, but none of them worked as accepted,and I don't know what carrier could it be... I'm even worried it may be a Latin American one (from Chile or Argentina maybe since that's where the firmware used was from) and I won't be able to get it.
I know there are websites to get a code, but I don't want to pay so much and risk getting scammed.
I tried to see if "entel" was a carrier to unlock it, but it didn't help.
Also, when I try to choose a network on Mobile Networks settings, the only available one is AT&T (which I don't use/have a SIM of), but when I accessed their website to unlock, it said my IMEI wasn't registered as theirs apparently.
Then, I also tried using Samsung's Smart Switch application on PC with the Device Initialization option, but when I try to use the firmware from that I get a SW REV. Check Fail.
I might be wrong, but I feel that since messing with the system files/root was what changed it, maybe I can fix it the same way with no unlock code or carrier help.
So, does anyone have advice, or know some other way to reset it? Or do I really have to go get it fixed/unlocked somewhere?

Did you ever get anywhere with this? I am trying to switch carriers from t mobile to boost on the Sm-j700f and I need to unlock it

I have a Samsung Galaxy A5 2017 SM-A520W, which I recently bootlooped and had to reinstall the firmware using Odin. However, when I restored my nandroid backup, the SIM card refuses to be recognized. It works in my other phone however (which I temporarily switched it while I fixed the samsung). So I tried resetting network settings, clearing the cache and other suggestions, until I finally decided to just factory reset the rom and see if it recognizes it from a clean OS, and it didn't. I can't see any reason why the hardware would be broken, since all I did was take the SIM card out and put it back in.
So then I thought about the firmware. I got it from here, which has a ton of different product codes for different carriers and countries. I'm in Canada on the Fido network, so that's what I chose (FMC). But Fido is owned by Rogers, which is a different product code (RWC)... So I'm wondering if choosing the wrong firmware will actually prevent the SIM card from being recognized? I can't understand why it's not recognizing it. >.<
Any ideas?
Thanks!
Have you checked the APN name and settings?
Hmm, I'm not sure I understand, can you explain further?

I mean the settings for the carrier like mmsproxy and ipv4, etc...
It's a longshot but it's in settings and network settings - mobile data.
I do not know exact english words used... Accesspointname if directly translated.

Do you get same notifications as when no sim in phone?
Hi. I received my Samsung Galaxy S22 Ultra 5G smartphone, which I ordered from Samsung.com (I chose the T-Mobile version when ordering). After turning on the phone for the first time, at the Welcome screen, when I click the Start button, I get the message, "Insert SIM card from your service provider for network service."
I can't find a way to bypass this message. I was initially thinking if I could connect to my WiFi, it'd go away, but there's absolutely no way to connect to WiFi or access any settings.
I upgrade my smartphones every 15 months and have had T-Mobile for nearly a decade, and this is the first time I've seen such a thing during setup. I like to keep my SIM card in my current smartphone until the new one is fully set up, at which point I would transfer the SIM card over. I have a lot of services I use that rely on SIM card (i.e., not fully cloud-based and are tied to the SIM card), and not having that service during setup may be an issue. Also, I have received brand new phones that have had issues in the past (e.g., poor battery life, screen problems), so I'd rather fully test the new phone before transferring my SIM over.
The workaround I thought of: Put in a temporary T-Mobile SIM card, just to complete the setup process. Once setup has completed, I'll put my actual SIM card into the phone, or have T-Mobile transfer my phone number to the new SIM card. Thoughts?
Thank you.
It's because you got the T-Mobile phone so it wants you to connect to the network first before using it or continuing with setup. A way to get around that is to install the u1 firmware.
IIRC you can hold the volume down button for 5 seconds at the sim required screen to bypass the requirement. There's a help article somewhere that documents this.
As far as I know, Samsung requiring a SIM card during initial setup has been around for a long time. Nothing to do with your carrier. Even my unlocked phone from Samsung required a SIM card on first boot before continuing. There are of course ways around that, but beware. I bypassed the SIM card requirement setting up my S21 Ultra and spent a day configuring it to my liking. Then I popped the SIM card in from my old phone and it caused a factory reset erasing all my hard work. Probably because my carrier wanted to install all their software and settings. Not saying the same thing will happen to you, but just something to be aware of.
Here is the link to the eSIM setup (bypass SIM requirement)

Sticking a SIM from another carrier after eSIM set up should not cause a hard reset under normal circumstances, it does cause a reboot into bootloader to deploy the new carrier specific customizations from cache, but this is supposed to be transparent to user data. It broke if it caused a hard reset ;\

Technically, this worked, but this burned me badly. I appreciate the workaround, but I highly recommend against it. See below.

This is exactly what happened to me on the Samsung Galaxy S22 Ultra. This is literally the most annoyed I have ever been at an electronic consumer device.
I spent over 21 hours over the span of 6 days setting up the phone. I put in the SIM card and was presented with a message stating, "SIM card detected. Restart your phone to start using your new SIM card." I could not use the phone at all, so my only option was to restart. After I hit the Restart button, the phone restarted. For less than 3 seconds, it showed a black screen with a small Android logo, with the small text "Erasing." Then the phone started up and everything is as if it's a brand new phone. Everything I've spent time working on is all gone.
Hello Team, important information, when it is asking for the carrier sim card, you need press volumen up + volumen down + power button at the same time for few seconds, then it will say a message like "Unlocked" then proceed with the first configuration.
This is for people who is going to use with a different provided, please let me know if you heard or read this info in another link (because i did not find that)
Galaxy S22 Ultra (SM-S908U1) USA model unlocked purchased directly from Samsung.
Running on T-Mobile. I replaced the original SIM card with eSIM several months ago so I have two different IMEI numbers.
Just updated the phone OTA to the June security update a couple of days ago when it finally became available for my phone.
Yesterday I tried to update some apps in the Galaxy Store and they wouldn't update. The screen just sort of jumped up a little, then down. After trying numerous times without success, I decided to try first signing in and out of my Samsung account which didn't work, then I tried deleting my Samsung account. When I tried to go back into Settings/Samsung account, I got an error message every time: "IMEI (or MEID) is empty". This same error message shows up when I try to sign into Samsung Pass, Accounts/Backup data, Biometrics and security/Find my phone, Galaxy Store app, pretty much anything that seems to have a tie in to my Samsung account.
I did a full factory data reset, but the problem is still there. I sort of remember updating a couple of apps in the Galaxy Store a couple of days ago and it worked fine. Could the June update process have done something to my phone, and how do I fix it?
Could be the esim that's at fault. Can you revert to sim card?
I still have the old SIM card, but it was deactivated when I had the eSIM activated.

Well, well. I decided to try your advice and inserted the old SIM card, then restarted the phone and...voila! I now have access to my Samsung account and the Samsung apps work. Thanks very much for your advice!
Missed this. Yes, if you insert ANY sim card, even a new, unused one will fix this. Once you sign in to the app successfully, you can remove that sim. Seems to be a bug introduced in the JUNE update.
That works for me until I turned the phone off in which case it lost the MEID again until I used another SIM.
if you use a non-working simcard, you will have problems with Apps & downloading. It stands to reason that this will occur. Plus ESIM is a relatively new addition and there will be bugs.
