Hey, I have a question for people who have unlocked bootloader - do you happen that once in a while, the phone does not detect the SIM card after a restart?
Because I have such a problem since updating to Android 11, it does not happen on a locked bootloader, but on unlocked sometimes I have to restart the phone up to 4 times in a row until the phone detects the SIM card. I have had this problem for several months now, no system update has fixed it so far.
At first I thought that maybe it was a defect of my model or my SIM card tray, but 2 days ago my girlfriend bought a OnePlus 8T, I unlocked the bootloader on her phone and the same thing started to happen, her phone also has problems detecting the card SIM now, did any of you have a similar problem and maybe found a solution?
I have the same problem as you described on my 8 Pro.
I haven't had that problem with my 8 Pro although I unlocked the bootloader and rooted it first before I put my sim card in and made sure I already did these and updated before even using the sim

It happens to my 8pro too once in awhile. I just need to reboot several times.
I have exactly the same issue with mine. In case anyone wants to start comparing notes, I have an 8 Pro with a fairly old Verizon SIM (actually was a Micro SIM that was cut down). I've found that it happens almost every time you reboot, but almost never if you do a full power off and then power back on. I don't remember having the problem with the original OOS11 but after 11.0.2.2 it started showing up.

I have my Galaxy S4 for a while now, and through out its history I have messed with it a lot.
I think it first happend when I updated my ROM to the newest Omega version, and every once in a while I was getting a Sim Card remobed error, and only restart now option - after each restart it worked normally until the next time.
Straight after I switched phone company and got a new sim, I started getting Invalid Sim card error after the forced restart, but not every time. To get it to work I had to restart the phone many times until it decided to work.
At first I thought the problem was with the Firmware, and tried to return to stock - but it didn't work.
Than I thought, maybe it is a hardware issue, replacing the sim slot didn't help.
The last option is replacing the SIM but it makes no sense because it works on otger phones, and the problem started with my previous SIM card.
This happened earlier today out of the blue. My phone is rooted with TWRP, but beyond that, I haven't done anything that I think could cause this. I don't have a custom ROM or Xposed or anything like that. It just randomly stopped seeing my SIM card. It also may be important to note that the phone was carrier-locked when I got it, and I unlocked it myself. Any solutions?
It's a VNS-L23 on build VNS-L23C45B130
Well, maybe you broke the sim slot.

Happened to me too. I changed the SIM and everything worked !
Thanks! I went to an At&t store and got a replacement SIM card, and it's working again!
Galaxy s7 Edge (snapdragon) from sprint.
I SIM card locked randomly while i was recording a video. I tried to flash stock it and did factory resets and nothing worked. I went to sammobile an did the latest rom atm. I have a history of rooting my phone and got bricked a couple of times but nothing I never heard of a brick that blocks your SIM card. Is this a brick problem or is something wrong with my phone? I went to the sprint shop and they said its not the SIM card.
is the phone working normal with exception of not being able to make calls ?
if yes, then it is a software problem in either the modem or csc.
if no, then your phone is bricked and you may need to take to a shop that has a box to fix it.
The phone is working fine. When I first restart my phone, it has service for a minute or two. After that it gives the warning that my SIM card is locked. So I'm not sure if it's a brick or not.
Hey, I've had my Moto X Pure (XT1575) for a bit over a year now, and it's been great up until I updated it to 7.0 a week ago. It has been saying "No SIM card" and I have been unable to do much with it. Rebooting the phone will fix the issue and cell service will work for for about 5 minutes, then it disconnects again. Taking the sim card out and putting it back in will also fix it for about 5 minutes. I have cleaned the sim card and port, but that has not helped. I have also tried factory resetting the phone but the issue is still there, even during setup. The phone is running stock android with a locked bootloader. Any help would be greatly appreciated.
Replace the SIM card...
Check if another SIM card is working fine with the phone or not. If yes, then you need to follow what acejavelin has suggested above.
Hello everyone. After a lengthy battle, yesterday I finally was able to unlock my bootloader, flash a global rom (via MiFlash) to my Redmi Note 7 and lock the bootloader again using fastboot.
However I've encountered an issue that is very annoying. Every time the phone boots, it fails to read my Sim card, so I'm forced to eject it and then reinsert it in order for it to work properly. I use an SD card and I tend to reboot my phone once or twice a week, so you can get an idea of how much of an inconvenience this is.
I'm pretty sure this must be a software Issue because before the ROM change, I've never had an Issue with this. My phone model is M1901F7H and the rom is Miui global (10.3 Stable 10.3.5.0).
I need to mention that my current carrier (I got the phone from them) disables the hybrid sd card/sim slot and sells the phone with only one working sim slot and a custom ROM. After installing the global rom I noticed that now I can enable/disable the dual 4G connectivity for both sims toggle (it was greyed out before) however that is the only option regarding the dual sim settings that I can interact with and the second slot is still only usable for an Sdcard.
Currently I don't care much about the dual Sim feature, but it has crossed my mind that maybe my current Issue is related to this?
Anyways, thank you for taking your time to read this post and I apologize for the wall of text.
I would be very grateful if someone could help out.
Edit: I forgot to mention that one of my banking apps is now unusable as it crashes over and over again since I've installed the Global Rom. Don't know if it's related to the issue, but it worked just fine beforehand.
Check out my thread.
I'm also on 10.3.5 and think the issue is software related.
After reading your post, I'm thinking we may have something similar going on. My phone is working fine with no problems reading the SIM card after a factory reset a few days ago.
Hopefully you don't end up having the exact same problem I did.
I also have the same problem, I have to take out the SIM every time I reboot, I have the derpfest ROM and so far I have not been able to solve the error.
