No SIM card detected after reboot - Xiaomi Poco X3 NFC Questions & Answers

Hey, is anyone else experiencing this problem? I believe it is a software problem as I just bought the POCO X3 NFC and the SIM was working fine, but when I rebooted the phone, it didn't detect any SIM card. It still detected the SD card though. After rebooting several times and taking the SIM tray in and out several times, the phone suddenly detected the SIM and everything worked fine. The next day I reinstalled MIUI 12, thinking that it may just be a bug as it seems it is a software problem, but upon rebooting the phone the same thing happened. I attempted rebooting and taking the SIM tray out multiple times, this time with no luck. I took out my SD card and put the SIM in that part of the tray and it now works more consistently, but still will not always detect the SIM after reboot and I must reboot and take the tray out until it works. Also I can't put the SD card in now. Any ideas?

What makes you think that it's a software related problem? I don't think there's much software behind simply detecting a sim card and you already said that changing to the second sim tray has helped a bit. I'd RMA that phone if I was you

Because it only happened when rebooting, once it detected it, there where no problems. If it was a hardware problem, it would probably have not detected aside from just rebooting right?

I'm facing ditto same problem bro can anyone gemme solution please

Phone won't turn on...keeps restarting

I've read in other forums of this problem but have not been able to find a solution (not entirely true).....when I turn the phone on in the morning, it just keeps restarting without going to the home screen. Sometimes it take 2 reboots sometimes more. The only way it will boot up correctly right from the start is to take the mem card out, so I think that's probably the problem, but it's not a corrupt or problem card. Once the phone starts and I put in the mem card all is fine.
I want to try to format the memory card from the phone, but don't know how to. Anyone else know how to do this? Also any other suggestions or solutions?
I got this once. Somehow i got the phone on. I just took the card out and put it in when its about to restart. Mabye it was luck, but i dont know. But if you get your phone on again, I would certainly format it (clear storage)
Does your phone ever act up again after that? Mine still does. It turns on fine without the memory card in. By the way, how do you format the memory card on the phone?
Mine rebooted all the time until I removed Facade. Hard Reset the phone and didn't install it and haven't had the problem since. I know Facade isn't "compatible" yet with WM6, but other than rebooting it worked fine.
Really....I'm going to try that and see what happens.
For those that have this problem, it's true. Once Facade is uninstalled and a soft reset, the problem went away....
I had this happnen to me for the first time today. I had the phone off all night (was testing another device) and then when I put my SIM back in and powered up it went into this reboot cycle. powerd off, even took the battery out still no luck.
Then I took the SIM out and tried to power up and it came right up. Powered off and put the SIM back and it worked agian first time.
Not sure, but maybe the SIM was not fully seated... since this was the first time I actually took it out since I get the VOX...and this was the first time I had the problem...

I had the same problem, although I never installed Facade, Initially the phone was fine and the it started re-booting on startup. I saw a suggestion of running SKtools and removeing duplicates in the Notification table, this worked for a while, then it came back again.
At first the only cure appeared to be to re-boot without the sd card inserted - inserting it again after the phone was running (it even had the same problem with a blank card inserted)
I then read abot someone putting the phone in Flight mode before turning it off - this also solved the problem - better than removing the card each time.

After hard reset - lost option to store attachments on storage card
I had the same problem and solved it by hard resetting the device. However after the hard reset the option to user the storage card for email attachments has disappeared from the pOutlook options screen.
The SD Card is OK and I tried to solve it by a new hard reset, but it is still not resolved.
I would be very graefull for the one that has a solution for this.
I have the same problem with my SD card.
With the card inserted the phone keeps rebooting.
With the card removed it starts normally.
When I insert the card when WM6 is running the card is normal accessible.
Tried an other card and also a 1 Gb card. Same problem over and over.
I'm going to try a Kingston card.
If anyone has a solution, I'll be happy to hear it.
i have my microSD inserted when i power on my Vox but didn't have this problem. what rom version do you have? my rom version is 1.15.405.2.
I have a friend with a similar problem. Would appreciate any further input on this situation. Has anyone taken a look at Paul's (from Modaco) answer to soft reset loop????
Check it out and see if it does anything. Want to know if that'll fix it before I take the phone off his hands.
Hi all,
Like many Vox users, I've also suffered from this problem.
I've noticed two scenarios which helped me solve the "boot-loop". Hopefully they'll help others.
I once had a GPRS monitor application installed to my strorage card. Re-installing to the phones memory helped me.
Also, when I had bluetooth turned on, I powered down, powered-up again, and the phone booted okay!
I think theres a few variables involved in this, and no single "silver bullet". Hopefully HTC will provide an official fix soon.
Michael.
Friends,
Thats all humours. Don't need to remove/install any software. All work fine except you reboot and remove your SD card.
Its simple: if rebooting occurs, just remove SD card and once booted, reinsert SD card, simple! nothing else need to do.
Its true that its a bug with WM unfortunately; i don't know when would it be resolved.
i have tried to boot up with 512MB & 1GB sd card but never had this rebooting problem. Maybe you can let me know your current rom code version and i will try to verify the problem?
I have got the same problem my phone keeps on restarting...
when i put the mem-card after restarting it is being opened as storage card 2, and default storage card option asks for turning on the bluetooth.
Re: Rebooting of Vox
Hi,
Had this problem once (and drove me nuts!, I was out on tour, no PC access nothing).
I formatted the SD Card (Its always better to use a card reader and format it from a PC.
Another I had this problem (hope you are not as dumb as me ):
I use TPC and set it to ultra slow . So every time I booted up, the CPU was not simply powerful enough to cater to the power requirement and rebooted. I had to do a Hard Reset. Hope you have your contacts backup before you go for a hard reset

If you have bluetooth file explorer turned on, it will show as a storage card
i had it long time ago with one of the official htc roms.
The solution is to make loose the simcard-slot in the middle of the booting.
Vox will turn off.
Close and start the phone again.
It should be over then.
Re: Official ROMs
Yeah! The official ROMs suck! actually the best solution will be to switch to a custom ROM from Dr G/FH / fireburned, they are much much better feature wise/ battery backup wise and speed wise. I think HTC should try using one of those ROM as there official ROM

Sim not detected!

My Polaris is not detecting Sim Card. I have tried:

c. Cleaned the connector itself.
Can someone suggest some possible solution for this issue......!!!
Same Problem Here
Mustking, I have the same problem although not as bad as yours. I believe it is the SIM card reader. Mine works 98% of the time and every now and then just goes offline. It then comes up with SIMcard not found.
See my post here... http://forum.xda-developers.com/showthread.php?p=3980181#post3980181
If you find a solution I am all ears!
I had the same problem where it wasn't working at all not recognising all sims i had to send it back to HTC they replaced something and the main Mobo

SIM card reading error. PLEASE HELP, im driving crazy.

Hi there!
So i got a NEXUS 5 32GB.
Short story: i had an old SIM card, like 5-10 year old, when i bought the phone. I cut the card into microsim, and worked like a charm. (You know, nexus stuff when no service sometimes like once in a week (restart solved always the problem)). Now i contracted with a new service provider, and the (3in1) micro sim i get is unreadable to the phone.
Detials:
-The new card working in other phones without problem.
-I went to my carrier and get a new sim card, doesnt work either. (so the sim card(s) not defected)
-Tried different SIM cards in my phone-> working only the old SIM cards, new micro sims doesnt
-Tried almost every softwere stuff, (factory reset, FR in recovery mode, flashing 4.4 android, flashing other androids, flashed radio files etc.etc) ->non of them worked.
-We disassembled the phone, the sim reader is looking perfect, not a scratch, all pins in order etc.
-THE MAIN problem: however i insert the new card(s), phone says only "No sim card, emergency call only". Can't even set up the mobile services, nothing. Only can turn on-off the NFC, Airplane mode etc.
-When inserting the old cutted card, works perfectly.
I'm paying now for 2month for the new card, but can't use it....
Please help me!!!
Any kind of help will be appreciated.
Thank you very much.
Have a nice day.
PS.: Sorry for my english, i'm from Hungary.

Sim card not detected

The problem arose unexpectedly.
After several attempts to get a sim card and insert it back, the error disappears, but after a while it reappears.
I cleaned the sim card reader. Then I changed the sim card reader.
Updated to Android 9. The problem is not solved.
Put sim cards of other oprethors - nothing helps.
Empirically, I found out that the SIM card does not fall off if you turn off geolocation.
After turning on the geolocation, after some time the problem returns.
How to solve a problem?
I am having the same problem with LineageOS 14.1

SIM not detected anymore disabling a SIM

I have Oneplus 8T with Android 13.
My SIM was on Slot 2 yesterday. Then I accidentally clicked on "Disable SIM".
Now it says "No eSIM" "Disable eSIM to u.." (it only shows second line partially) when I insert it in Slot 2.
When I insert it in Slot 1, it says "No SIM card detected".
Note:
1. If I use any other SIM, it works on either slots.
2. When I this SIM on other android phones or even a feature phone, it works correctly without any issue whatsoever.
3. I've already tried the "Reset Network Settings" feature. Ideally I don't want to reset my phone completely
Have the same issue too, can't figure out any way to fix other than getting them to send out a new SIM card each time...
Anyone else have any other ideas?
(Edit, just realised this is on a 8T forum, mines a 9 Pro... seems to affect lots of OP devices)
I factory reset the device - SIM starts working immediately. Disable SIM 1 and the phone instantly forgets it again...
Back to wiping it all over again. Thought I'd rather test it now before I set it all up
