For a while, i mean since i reinstalled the android 4.0.4, my huawei mediapad stopped recognizing the SIM card. (for example,if i insert the simcard while the tablet is on, the window "Sim card state has been changed, restarting in 9 8 7..." appears, but after the restart, it boots normally, as there was no sim. (i mean, it just starts, without requesting the PIN or anything else, and runs absolutely normal, as it was with no sim)
What should i do in order to make the SIM (3G) work?
Hello there fellow devs!
Strange issue encountered today. Dual sim functionality stopped functioning today.
Only the second sim works. No ideas what to do. ROM flashing doesn't help, Factory reset is also futile.
stock ROM results in both my sim cards being deactivated and it show that there is no sim card.
AM i Officially screwed???
So, I've had a lot of problems with my phone lately, including a semi-brick for a while. After all this mess, I had to do re-partition, fix WiFi and stuff like that.
Recently, my only problem was no service after inserting SIM card in CM12 (basic stock ROM using Nubia Tools, repartition using official 2.03 ROM from NeedRom & finally CM12 for Nubia Z7 Mini from NeedRom). SIM card was fine but there was no service, I've tried re-inserting it, I've tried different SIM cards etc.
The issue went like this: phone crashed and "turned off" after inserting SIM card. It wasn't really off - Windows was detecting it as several storage disks (?), and it was heating up after a while. Long press of a Power Button made it reboot to system and it was running fine, but only without SIM card. SIM card made it freeze, heat up and the issue was happening all over again.
Currently, I've tried to fix that by flashing latest Resurrection Remix. Now, phone is stuck at "emergency calls only" - it tries to find service but without any luck. I've read that it might be an issue with bootloader - that there is some script that is trying to run, making it unable for the SIM card to grab service. The phone is really heating up with SIM card in it, but it definitely detects it and it tries to find service without any luck.
Maybe flashing only modem would do? But I can't find it anywhere.
What can I do to fix it? IMEI numbers are fine, on their right place.
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 really weird problem appeared on my device after upgrading to the latest miui 8.7.19 global beta from the 8.7.12.
After this update my secondary SIM slot stopped working. It reads the SIM correctly but it can't connect to the network.
If I put the same SIM on the slot1 it works, if I put it on the slot2 it doesn't work.
It's driving me crazy because I have the need for 2 SIM for work.
I already tried to revert it back to the old ROM via fastboot formatting the phone but it did not help. The problem is still there.
Can someone please help me? thanks.
