Hi, I've had some issues with SIM cards in my Mi A1.
I've tried rebooting and I've tried both SIM slots, but neither of them are detected. "No SIM card - No Service" shows at the top of the screen. There's nothing wrong with the SIM itself, it works fine in my old phone (a Redmi Note 3) so I'm not sure what to do now. Everything worked fine yesterday and I haven't dropped it, splashed it with water or anything since then.
Any help would be appreciated, thanks
hello brother please imei number check
hey
I'm having the same issue. How do you fixed it?
Thanks
I had this issue too, try restarting the device 2 or 3 times. If it doesn't work, try doing a factory reset.
was anyone able to fix their SIM issue?
my Mi A1 received an OTA update last month and the "SIM card not detected" msg
when I check my Network Settings, the menu options are all greyed out and i can't do anything with it
i've tried flashing many different versions of stock/custom ROMs
i've tried a variety of different SIM providers (Rogers, Koodo, Fido, etc)
i've even flashed a few modem versions to see if it would fix the signal (cuz that's how i used to fix my SGS2)
but nothing works... it's behaving as if there isn't a SIM card inserted at all
...which is leading me to believe that this could be a hardware failure
anyone with suggestions on how i can fix this? cuz otherwise, it's a great device... it runs AOSPExtended like a champ
thanks in advance

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,
I had CN ROM version with Kit Kat. Everything worked fine but one day I lose sim cards. I mean sim cards weren't detected and WiFi was 'Switching On' I mean flashing. Phone is constantly restarting by itself. I've done several factory resets, take out the battery and flashed phone with ROW ROOM (I've change the NON-HLOS file to get network) but nothing helped. Flashing went ok and I've got new ROM.
Phone is restarting after few minutes. I can not switch on WiFi and sim cards are not detected. Do you have any solution for that?
Thank you!
Hi,
I am having weird issue with the device, the sim card slots automatically getting ejected/disabled with in 5 minutes of device restart. I have to restart it again n again to make it stay.
Sometimes it stays upto 2-3 hours and then gets disabled, i have tired with different SIM cards the same issue persists with them.
I have ran the SIMI test ,it says working for two sims when they have network and if i do test after sim slot gets disables/ejected it shows "something wrong".
Is this related to software or the hardware??
I have the issue with both .313 and current version.
Using Airtel and Jio SIM.
any help?
Sim card is not detected
I'm having same issue, none of my sim cards show up it just says no sim. Also I'm on stock rom, never rooted or tinkered with in any way but upon checking the "root integrity check" in boot menu it says test fail . Could really use some help
Probably Google play services error update to the latest stable version.
Hi all,
I have a problem with my XC, i hope there's someone here who could help me out with this .
I get a SIM card error when i start the phone. After a while (5-10 mins) the error transforms into "No Service" as if the phone now detects the SIM card but has no service whatsoever.
Things i did to my phone prior to this:
- unlocked bootloader
- installed custom recovery
- root
- installed custom ROM
- drm fix
The phone did function properly for a few months actually after these operations without a SIM card error even once. But then i tried to install custom ROMs again (and i'm sure didn't flash ROMs not suited for XC) -actually tried to install "existenz" ROM but i did get a bootloop so i -once again- did the usual procedure with flashtool and flashed a firmware to set everything back to stock as close as possible. That was, when i started to get the SIM card errors. After several restarts (cold and warm) the phone sometimes recognized the SIM card and i could use the phone normally. But this was true only till the next restart, where i got the same SIM errors again.
Things i tried:
- flashed several different firmwares (official) with flashtool (wiping everything) - all the newest firmwares.
- *#*#72786#*#* in dialer to wipe carrier settings
- *#*#4636#*#* in dialer to go into phone settings and changing those settings randomly
- flashed another AOSP based custom ROM instead of stock sony
- wiping and formatting everything between the flashes of course
- cleaning and re-inserting SIM card (which i never took out before anyway)
But unfortunately nothing worked. Phone keeps to not recognizing the SIM card (which is working just fine in another phone). Everything else works just fine on the phone. The IMEI is displaying correct. I'm almost certain that the fault isn't hardware-based (i didn't drop the phone or exposed in water etc.) but software-based. Did i just managed to brick my phone by flashing something related to the modem which i'm not aware of?
I can't find any solutions on google, which help me, which is why i'm posting it here. Sorry for the long post.
Did anyone experience such an error and/or knows what else i could try to fix this? I hope for answers
Thanks in advance!
Anyone?
I've got the same problem.
I didn't unlock the bootloader or anything prior to getting the bug.
I wanted to downgrade to nougat, because aparently it helped someone in the forum below, but I didn't manage to do it.

Did you try nougat, when flashing different firmwares?
Your post makes me question if its worth it, trying to downgrade.
Try to remove sd card if you have one. then restart the phone and see if sim card is recognized.
I had the same problem and I think it was a hardware failure in the end.
I also tried almost all the things you were writing above. In my phone it started slowly. Sometimes the SIM was detected but after some time the connection was lost.
It happened some time after I installed a new battery.
But since there are no original batteries available for the device anymore and the new battery was even worse than the 5 year old original battery, I gave up investigating the SIM issue and don't use the phone any longer.
I bought a new (used) x compact because I still like the size and I saw some development was going on for this device.
In the end I cannot tell whether the SIM was not detected because I broke something while changing the battery or due to age of the phone but I think it was a "normal" failure.
I also read from others that they had the problem and the SIM was working for some time after I switched the battery before it stopped working.
Nevertheless. Good Luck to you. Maybe it is something different on your phone.
Hi All,
Recently my one note 5 (N920I) experienced no SIM card error and i couldn't make any call or on data for my phone. I've tried below method but still couldn't solve the problem. Hopefully someone can help me or advise what i need to do. I haven't root my phone yet though. would factory reset solve my problem?
1. tried re-inserting the SIM card and retart the phone
2. tried to delete the cache data on the phone
3. tested SIM card is working on other phone
4. tried to check though the software/firmware details and found that baseband showing unknown
5. found IMEI is missing from my phone when entered *#060# but i'm able to retrieve my IMEI# through other means
i have that issue too, for some weird reason 2g seems to work. calls can be made and answered but mobile data only works on 3g or 4g or 5g.
if you set your phone on 2g only, it should recognize the sim card
