my phone lost signal iregullary... if my phone lost signal, it said that my sim card ist not detected. But after i reboot the phone, the signal is back until it lost again by itself and i must reboot it again. This happend very iregullary. That's why i cannot said i happened after i run any apps or after i do something with the phone... i try already a lot of modem, but the problem ist still there... i try also to format my efs folder and restore it again. it works for 1 day, but after that i lost my signal again. This happened very oft (maybe 2-3 times in a day).i tried also to flash different ROM, but the problem is not gone.
The problem is there since i upgrade the android from 2.3.6 to 4.0.3.... now i am in Custom Rom XWLPT. The provider is O2 Germany.
can somebody help me with this problem.
I had this problem also... try another sim card... that was the only thing that worked for me... i went to my provider and got it exchanged with a new sim card. Ask for a 128kb one.

i need any advice or help with this please, ive tried flashing another rom and also changing recovery with no luck
Sounds like a bad sim to me. Get a new one from your carrier and see if the problem goes away.

I own a Lg G3 sprint ls990.I live in Bangladesh.My device was on android lollipop and it was fine.But due to restart and warming issues i flashed into stock kitkat rom using flashtool.After 91% of flashing a red screen poped up in my device it said "warning; not support qem=0" and in the flashtool app it said failed.But when I pulled out the battery and rebooted my device I saw everything is okay.Then I put on a working sim card and it couldn't detect the sim card.i tried with whole other working sim card but i couldn't detect.I changed my sim slot but that also cannot change the condition.I flashed with other roms but still nothing is happening.When i dial "*#06#" to know my imei it says "connection problem or invalid mmi code".......Now Im badly in need of your help guys.Please,do help guys.
so yesterday i was on my max 2 just playing a game when suddenly a messeage popped up in the notifictations about "no sim card detected" so i tried to remove the sim and re insert it but nothing,tried to switch roms with a reset and still nothing,anybody help?
P.S:the phone was shipped with only one working sim slot but i dont really use dual sim so i didnt care but now it dosent work and im scared that this is a hardware flaw

What is your provider? I have the same issue with a Sim card of the German Telekom. After 3 weeks of use it stopped working. I put in my second Sim which works for the moment. So the Sim slot is OK.
the sim works with other phones
Same problem, my sim was broken after 2 weeks.
I get a new one and phone works fine again.
Try to flash this zip via twrp
Same problem here... I have flashed andr68rus patch, but it does not work.
Problems start after flashing SmallEUI. Now I have flashed back the stock 20S and make a full wipe (including system) before. But there are still no SIM cards are found. When the phone is powered on and I open and close the SIM card slot, it found SIM card 1. but not second one.
After a reboot SIM card 1 is gone again. I have to open and close the SIM card slot again.
Any idea? Is this only a strange coincidence and my phone is defect or does smallEUI change something in the firmware or baseband files?

Maybe, but I experienced the same thing, also with small EUI, IIRC. Pulled my sim and put it in the wife's phone, and it worked ok, and hers worked ok in mine. Put mine back in my phone, and no dice. Flashed stock20s to try to fix it. At one point, I re-inserted with power on, and it was recognized, but my LTE went away. Was like that for a number of hours, and suddenly, after a couple of reboots, it seemed to come back to life.
Currently on AOKP MM, and I am floored by how nice it is, compared to everything else I have tried. I seem to have an issue with USB file transfers, and the LeEco camera doesn't work, but I've never seen the phone perform like it does now..

It's happened with me too. Do you find a solution?
It seems that the second SIM card is really broken. I test it in two other phones and they will not detect it too. When I remove the second SIM, the first SIM ist detected normal.
In my case it seems following problem: https://www.golem.de/news/defekte-s...en-die-probleme-fuer-oneplus-1603-119620.html
i runned into the same issue after flashing CM13 from TEAMSPAIN
After flashing CM13 from teamspain, my sim card stopped working. I flashed many other roms but couldn't make work. Then i downloaded the official rom from leeco website and after installing it, everything is back to normal and obviously my sim card slot is working again.
works with oreo ?

A time ago I used two SIMs on my phone and they worked well.
Now that I tried again, the SIM 2 don't have service and if I change position of the SIMs then the SIM that was on port 1 stops working and the other works...
SIM 2 is recognized but no signal on it.
Any help..?

Sounds like a problem I'm facing. I had a ANE-LX1 single sim and I successfully flashed the dual sim oeminfo and dual sim rom, now I get dual sim working only when a specific sim is set as the main one (the one set for data traffic). Is it your situation?
I'm going to root the phone again to check if some update messed with the oeminfo, then I will try to force flash another dual sim rom to see if it helps...
Same problem here - currently running latest firmware available 9.1.0.257 (C432E6R1P7). Can`t force the phone to work on both cards at the same time. Works only the one set as data card.
TIA for any ideas
