I've been running the official release of Android 11 on my Pixel 3 XL without issue other than I'd like the battery life to be a little better. Had a really weird issue that maybe someone might have some insight about. My sim card only works on Android 11. If I run the official Android 10 from August, no sim detected unless i take it out and put it back in. I select the apn and I don't connect. Upon reboot the sim is not found until I take it out and put it back in. I tried Havoc GSI (10) and PixelDust (10) custom roms and don't connect with them either. Used the Android flash tool back to 11 and sim works without issue.
Figured it out. If I unlock the bootloader, the sim doesn't work. Never seen this before on a phone.

Recently I flashed a Rom Android 11. Unfortunately,for First Sim HotSpot cannot share. It means connecting device can't use my net. It seems to be device connected. For 2nd Slot Sim has no problem. This problem only for that particular Rom. Other Roms I checked has no problems for both sims. I'm using One Plus 6 device. No problem for sharing from OOS and Other Roms. Can any One Explain. Why I am?
After updating to the latest update, android 11 global for poco f2 both my sim card slots have been turned off.
When i try to turn on sim1 it tells me that only 1 sim card can have 5g enabled and to change my network settings.
Unfortunately none of the slots wont turn on so i cant change the network settings for either sim.
Have tried putting in 1 sim and restarting, in either slot 1 or 2 the sim slot still wont turn on.
Is there any other way to do it other than a factory reset?
I have same problem with you. I cannot turn on sim card 1 or 2. İt is very weird problem. Did u solve the problem ?
A hard reset maybe help

Yeap i did it. I had another bugs after the update. But factory reset fixed all of them
This version (stable BETA) in android 11 has multiple bugs. Many prefer to revert to the previous version.

Great,! Wish I'd bloody read this thread before I updated. At least I know now, it's not just me. Unfortunately, for me at least, I'm on stock & haven't modded, unlocked bootloader, rooted or flashed anything at all. Does anyone know if Xiaomi's backup utility is any good or shall I not bother before I factory reset?. Cheers.
I checked my IMEI on Visible's website and it checked out. I am running the Android 11 Pixel Experience ROM and Google Fi SIM worked fine, but I cannot get the Visible SIM to even be recognized as existing in the tray. I tried both SIM slots. Does this have something to do with being rooted? Ironically I installed this SIM in my Poco F3 which is NOT compatible, and although I got no service, that phone did recognize the SIM and even all of the Verizon APNs. Just wondering if you guys have any thoughts? Thanks.

It shouldnt have anything to do with being rooted, but if you have converted/changed firmware then that could be the issue.
If you have the engineering mode app installed u can check the sim in *#808# or by adb shell am start com.oneplus.factorymode/.manualtest.SimCardTest . If the test fails then the modem or your efs is messed up.Hopfully you have a efs back up. Try starting over with MSM flash first.I believe the fail sim is caused buy a key that is in the locked sfs folder of the efs. I do know for a fact there is a RSUprivate key there also. And have obtained it. But still have not found a way to write this back, other then efs restore in twrp.
I'm guessing it is related to the ROM.

I'm on visible and I'm using an unlocked T-Mobile gm1915. When on the global rom, it gave me a pop up to instructions for using the verizon sim on a cdma-less device. However, I didn't have to do anything and the sim started randomly working after waiting 5-10 minutes. So, i recommend just leaving the sim in for atleast 10 min and have mobile data on.
Technically the sim sometimes gets detected if I keep restarting the phone but after having to restart it 13 times earlier today to get the sim to work i decided it wasn't worth. I saw the fix for OOS12 but I wanted to know if anyone knows of a way to fix it for AOSP based roms?
So I have lineageOS 19.1 (android 12) on my tmobile variant oneplus 9. It was a long bloody war and much sleep was lost along the way. Everything seems to work okay, kind of. Phone gets stuck in fastboot for 2/3 times every time I restart it. And I have no data or sim card even detected when it does boot. I think it all comes down to the modem.img. I assume that I just need a modem.img from a stock android 12 tmobile variant, so if anyone could supply me with one of those (I have searched and haven't found one anywhere) I would be quite thankful.
Or if you know something I don't and that's not even the problem, please let me know.
