1. Try changing radio.
2. Get a new phone. It seems to me that something broke in hardware.

[HELP] Sudden problem with both SIM Cards not being recognized on any ROM

Good day! I just want to ask if anyone has an idea of how to solve a weird and sudden problem that happened to my phone a few days ago.
I was running Cyanogenmod R16 with Xcelerate kernel.
I use two SIM cards on my phone, but I do not use the first slot all the time, so when I'm not using it, I regularly disable it through the SIM card settings, and enable it only when I need it.
What happened is, when I tried to enable it, suddenly both my SIM card slots could not be recognized (The SIM card settings could not be accessed; and error says: "SIM card info not available. Menu cannot be accessed"). In the lockscreen, it says: "INVALID CARD." for both SIMs.
I tried both restoring a backup and going back to stock MIUI, but still, the problem was there; none of the SIMs could be recognized (I tried using other SIM cards too.)
My IMEI's for both SIM slots are fine.
I've looked up on other forums, but I haven't found any others with a similar problem on the Redmi 1S.
If anyone knows what I need to do to fix this, I need your help. Thank you very much.

Have you tried both sim in other phone..?
If yes,and both working then should be problem with your imei!

Yes, I've tried both SIM's on another phone, and they work fine.
Since my phone still shows both IMEI's when I look for it, I assumed that there's no problem with them. What are possible problems that concern IMEI's? So that I can look up on general IMEI problems.
Thank you very much!

May be this can help friend

Thanks for the reference. Backed up my IMEI and Restored it right after, but still no change. Still, thanks!
EDIT: I've already tried two newly bought SIM cards, and the problem is still present.

Was this solved? Happening to me right now..

Happening to me too... Unsolved

For me just blowing in the sim slot & reboot fixed after few times..

if you have TWRP backup your modem & efs partition, just restore it via twrp. it worked for me

Hello,
I have a similar problem.
SIM2 is not recognized at all. I can use SIM1 only.
Tried to switch the SIM cards and still SIM2 is not recognized.
Both SIM cards are working great on other phones.
Is it OS related issue?

I've got same problem. Try to clean the sim metal contacts carefully and gently with an alcohol and qtip or tissue. It solved my problem.

Sim card(1) "Sim card not detected"

hi
I have a very annoying problem whit the sim slot 1 (i currently test the slot 2)
Very often, the phone tell me "Sim card not detected", and i have to open the phone, dismount the card and put in again.. until the next time.. like i said, it's occurs very often, 10-15 a day..
Even when the phone is on the table without touching it..
I have rooting it and thats it.. 2.19.40.22
I would like to know if someone have similar problems before i try to reflash whit older stock rom??!

It happened to me briefly- After flashing my first full back -up back to the fone --then i did a factory reset and this fixed the sim slot problem

Hi, I think i have the same problem after testing the Cyanogen build for ZE551ML. Have you did a factory reset from recovery (wipe data, cache and dalvik) or a full stock rom flash ?
Thanks

Above, I was referring to the full 5gb asus ROM back up I made immediately after unlocking bootloader installing twrp and rooting, I installed svn ROM and backed that up too..stripped svn ROM further..backed that up too. Then went about trying my Asus full original...sim 2 was only detected..so did a factory reset and sim came back.
To get sim recognised in CM,I had to wipe usual..install..set up...and factory reset it...hope that clears it up a bit lol

Oh,try a reboot after factory reset..I forgot to put in description above

Guys can you check your sim holder lock . I mean when you put the sim in holder check if it is properly fitted. Issue is some SIM cards are thinner than normal and sim holder unable to grip it. I faced same issue.

Also recommend using ASUS ZenUI app called ASUS Support. There are several helpful tips with basic troubleshooting techniques for your device including including SIM card troubleshooting. Please go to Apps/ASUS Support/Assistance/SIM Card/Sim card not detected

Sim Card not detected
Hey guys,
I am having a similar issue. I have 2 Sims, AT&T and GCI (local carrier). AT&T Sim works in both Slot 1 & 2, and GCI Sim works in slot 2 only. The AT&T sim is a standard MicroSim and the GCI sim is a Tri-Cut sim, so basically a NanoSim in a Micro Adapter.
Sometimes when the GCI Sim is in slot 1, it will recognize for a couple seconds then go gray..

I to am having the same issue. By chance did you solve the issue? I love my Zenfone 2, but am frustrated by not being able to use 3G. I've tried a few differant methods to fix it. No luck yet.
Please if you have a fix let me know. reply here, or email me at bupbup777 at gmail.

I subscribe to the "theory" that some SIM cards are thinner than others and they drop out of slot 1.
In fact, I have 3 SIM cards and they range in thickness by around 0.5mm according to my cheap chinese mircometer. I don't believe that it is coincidence that the thinner ones lose SIM detection more than the thicker ones.
Also it is no coincidence that slot 2 doesn't lose detection becuase the SIMs don't slide upwards out of slot 2, but they do slide downwards out of slot 1.
Do this experiment: Put a SIM in each slot, now place a 3rd SIM in the space between the two. You will notice that it sits easily in the gap between the two installed SIMs with a bit of free play. Put the back cover back on and use the phone normally for a while (a day or two). Now take off the phone back and tip the phone over, does the "third" SIM fall on the floor, or has it been gripped by the SIM in slot 1 as it has gradually slid out of its slot?
Since I put one layer of sellotape on the back of all my SIMs, I have not had one single "SIM not installed" message. I used to get them all the time, especially with one of the thinner SIMs in slot 1 and above all when using the phone in the car (the fully vertical position and the vibrations seemed to have accelerated the SIM slipping out of its slot).
By the way, I never had the SIM slide completely out, but they certainly are not gripped sufficiently in place and slip enough to disconnect.

I had same "sim card 1 not detected" issue.
It worked back when i did soft reboot,.
And no more issue after factory reset

Re @ leftrand earlier on page 1.....
Sorry not been here in a while , but I think this was related to an earlier twrp we used , fixed with the later one I think. So it was a matter of restoring full original bk up,then factory reset then set up again and do another bk up. Keeping original bk up just in case . That was a while back now and should be fixed

facing same problem... only after updating ota. always.. sim 1 is not detected...

That no way to have a sim 1 working thru TWRP back up after flashing the CM13. What I did was doing a clean flash with SuperZen - 2.20.40.156 Full.
The problem was solve. then I flash back my back up TWRP. The phone now work like a charm.

I got it fixed bro! the phone does not like the Nano sim cards in the adapter. I happend to find an old GCI micro sim and had them activate it. works great now.

ok i found a solution. i read a earlier reply saying you cannot assess sim 1 whilst using a recovery back up flashed. i was currently using cm13 nightlys and this morning i flashed paranoid 5.1 or so.... i wanted to go back and compare the two but what i did was restore it from a backup.... so what you should do is when wanting to change roms, KEEP THE ZIP FILES THAT YOU USE TO FLASH THE ROMS WITH!!!!!!!!!!!! im still asking you to back up roms (preferably system before you flash) just so you dont hard brick it.
bottom line is back up rom, but keep zip files for when you want to change between roms. hope i can help

I have this problem, compounded by the fact that it seems all Android 6.0 (or possibly all CM based ROMs for the ZenFone?) have an issue where losing cell signal in a dead zone permanently breaks the radio until the device is rebooted. Even if the SIM is recognized, after going through a no signal area, the signal never gets acquired again and the SIM information lines remain blank or unknown. Trying to refresh the networks or providers list throws an error toast.

Question Z Fold 3 constantly reboots

Hello, guys
first sorry for my bad english
I will try to describe my problem
so my fold 3 keeps rebooting, but only when I'm not using it, only when it's locked and nothing is running in the background. So far, the only way it works is to turn on the app from the local radio and the volume to 0 ☺☺☺ so it has to work in the background and if I put it on pause it reboots... please help
I tried everything I found on the internet:
- put official android 13
- factory reset
- after factory reset, tried without installing new apps
- battery device care > auto reset OFF
- deleted wipe cache
- safe mode > reset anyway
- test using Samsung Members > everything ok
I have no more ideas

try these:
remove sim card and see if reboots
plug in charger and see if reboots
put in the fridge and see if reboots
let me know if it worked

So i put wife sim old sim butt same operater and it reboots after 3min
I will try sim with different operater

ok so i have news
i try with different sim new one from tcom and same problem. after 5min it reboot himself
i go to my operater for new sim same problem it restarts
then i got mad and do factory reset butt this time without logging on google account or Samsung acc
and now it past 2h and he didn't restart
please guys help !!!!! don't know what to do

So after that, restarts with only insert sim card to device even new one for me looking like unfortunetly hardware issue and need send to service.
Esim in my opinion didn't resolve problem or only in half because device will be full working especially with sim card which enables fundamental function of phone like connectivity.

Question No Network Connection (RIL Dead)

Hello everyone. I have a realme GT Master Edition (RMX3360).
The problem I am facing is that, SIM network does not work. SIM is recognised but it won't connect to any network, so basically I cannot use the SIM card even though the phone knows what SIM is this.
I did try:
Factory reset.
Use Force LTE app to access phone information and switch bands (I noticed radio toggle is switched off, I tried turning it on but it won't).
Unlock bootloader, just to increase my chances.
Flash only modem/hlos/... related partitions. Did not work (phone bricked).
Flash OFP firmware. Did not work.
Flash EDL firmware (C.09), which I am currently using. Still same problem.
Different SIM cards.
My IMEI is fine, it is recognised. My baseband version is 4. I did search for the issue in realme community, and it seems quite popular as a lot of people suffer from the same issue on different models.
I live in Sudan, we got no 5G, no VoLTE or whatever. Could you help me please?

I have similar problem after reboot .I can't connect to network or it tooks long time . What helps me is switching to airplane mode.

Switch to global rom maybe your sim card provider not supported switch to Rx3363

Thanks for the suggestion. I did install RMX3363 EU ROM from EDL, it booted fine but the phone still won't connect to any SIM network.
I will also try Russia ROM to see if it would make any difference.
Update:
I did flash Russian ROM from EDL, still does not work. Modem version is also still 4. I will try Chinese ROM next.

Try Latam version this what they put in middle east but so far i think its hardware issue did u try the sim card on another phone? Did you try another sim provider on your phone ? Sometimes if the sim card too old it wont work

That LATAM version is 18 Gigabytes haha. It'd take a few days to download.
I came to think it might be related to modem images as it showed the same version repeatedly on both RUI 2 & 3. So I'll try different modem images.
Also I'll try custom ROMs and GSIs. If it failed I'll return the device as a very last resort.
Update:
I tried latest Official ProjectElixir till date, still same problem.
Update 2:
I gave up the device and replaced it with another one under warranty. I will not buy another realme phone anytime soon.

I have a Xiaomi device too. The new virtual proximity sensor depends on hand movement to function. I don't use MIUI, but it is very fine at all situations.
Also I got a (256/8) GT Master replacement which is surprisingly working fine; being the same RMX3360.

It was already updated to F.03, I heard there was screen flickering or something but I didn't notice any so far.
But I did notice the battery was draining fast on mobile data. Really fast.
Besides, I can always lean on post-market development.

The general feel of the update is slower than the android 12 version
The battery will get better with you try to froze the app you dont use
