Hi All,
I was hoping someone would be able to assist this issue that I am facing. I have a S21 Ultra purchased a couple of years ago in Sydney, Australia.
Recently, my SIM card stopped working on my S21 Ultra. Every other feature works and the SIM card works fine on a different phone. I have also tried replacing the SIM card, but it still does not work. The same SIM card works on a different S21 Ultra phone.
I also reset the network settings and yesterday I performed a full factory reset, but the SIM card still does not work.
I tried searching for a solution here, but could not find any threads where someone has faced a similar issue. If someone could kindly help or suggest some other tips, that would be highly appreciated.
Cheers
Have you flashed any custom module/ ROM/ firmware on your phone?

Thanks for your response. Nope, just the usual OTA updates.

Have you tried putting another sim card on the current slot that isn't working?
You have the following two options:
1. Assuming your current sim is in slot 1, try putting it in slot 2 (or vice-versa).
2. Try eSim with your current number.
The issue appears to be the firmware that came with the latest OTA update.

Yup, I have tried another SIM card but that doesn't work. That sim card works successfully on other phones. Also I just have a slot for a single physical sim card. Thanks

If a factory reset doesn't solve a problem, you'll have to wait for the next update. For now, eSim seems to be the only solution.

Yup, seems like it. Yes, I will try and get an eSim and see how that goes. Thanks for your responses. Appreciate it!

Can someone please help?
Few days ago my phone stopped recognizing sim cards. No mather what I've tried, it still won't work.
It's acting like there's no sim card inserted.
IMEI is still there
I would appreciate any help.
I posted a picture of the problem.

Well, I'm not sure about the problem; if you are on a custom rom, it might be because of that, or incorrect flashing. Try using another ROM, and if problems persists try Stock ROM meant for your region. (it might be possible that you flashed a ROM for a different region and because of that you might have a problem..)
AND NEVER POST YOUR IMEI NUMBER ONLINE.

Thanks for the advice about IMEI number, i didn't think of that because i went crazy because my phone doesnt work.
I'll try with stock rom.
I flashed original stock rom on the device, but the problem remains. Does anyone know the solution, I am going crazy

pop your sim card out for 15 min. then put it
back in your phone.
In the second pic it is clearly showing 1 bar of signal
So how can you say sim is not being detected
No way out here

Did you notice the the SIM symbol with question mark inside it?
The phone acts like there is no SIM card inserted when it is inside all the time.

Thanks for the advice, but that didn't work. I tried several SIM cards. Same thing every time.
have a read tho these answers, maybe you'll find a solution http://bit.ly/17Ku2cc
I've been reading several threads and tried the work around being posted but none of them worked. My n7000 still recognizes my old sim, i want to replace a new sim card to get a bit of privacy but when i inserted a new sim card i get the "insert sim card" prompt and only have emergency calls and wifi. I even tried several roms including the original JB update we have on our country but none of them solved my problem. I would like to seek for an advice on what to do so i can change a new sim.
I hope you guys here can help me out.

Yes i even tried it on other phones and its working fine.
I just updated to the new BQL1 firmware and now my sim card is saying it is not registered on the network. I replaced the sim card and it was working until my battery died. I charged phone and turned it on and now sim card not registered on network again. I have reset network settings and toggled everything I know how to try to get it to work but nothing helps. Has anyone else experienced this problem? Sim was working fine on bqk5 firmware. Thanks.

I upgraded from G950USQU1AQG4 to G950USQS2BQL1 today and had the same issue. Even factory reset didn't work. Bootloader changed from 1 to 2 so going back wasn't an option for me. Registering a new sim card was the only option for me. I only tried a new sim card because the vzw site gave me this message while trying to re-activate the one i had been using:
HTML_COTENT_NOT_FOUND_FOR_CONTENT_KEY: devicechange_sim_aging_message
Glad i wasn't the only one who wasted a day with this crp.
Can we upgrade BQk1 to oreo?

I'd updated to Oreo from BQL1 and am trying to Odin back, but it keeps failing. Anyone have any suggestions? I'm using the 3.12.7 odin.
Thanks!
All good. Re-installed the samsung drivers and everything worked perfectly.

Try using Odin3 v3.12 PrinceComsy to roll back to GS950USQU2BQK5.
Also, did you activate the new sim card on the vz website first?
I'm pretty sure this is what I did...
Factory reset, shutdown, remove the old sim, activated the new sim online, insert the new sim into the s8, turn on the phone.

Can we roll back to the previous firmware from S2QBLI back to U2BQK5 so I can then root my phone and use my hotspot

Can someone please post a mirror to the firmware, every site I go to download has a d/l speed of about 15kbps and I can't be annoyed with that. Thank you!!

I can see my IMEI in sim card options
MotoG5sPlus (Sanders-XT1805-32go-Havoc-v3.0-25122019)
If you have a 2nd slot for the sim, try that. Or get a news SIM - that one may be bad. It happens

Hey. I have the exact same problem right now. Have you sorted it out?
I think your SIM card is broken.
