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,
After having problem with stock rom (while calling/answering, screen goes off, buttons don't work, untill the other side
ends the call), I went to CM10.2 last nightly build 29th october, both sim slot do not recognize my sim card.
I have checked the sim, it works fine.
Any help will be highly appreciated
I see that there are some people that are successful, I want to warn some people though...
Do note, My phone has encryption enabled.
I just finished updating the LG V10 (Dual SIM) to the latest marshmallow, what has caused the phone to stop booting up properly! As I have encryption enabled, Now every time it boots up, it gets to the code screen, pops up a window "A new SIM has been detected, would you like to configure it now?", and there is only an OK button, the "back" button does not work, so I can only press on OK, which reboots the device, and brings me back to the same screen...
I have removed one sim - problem still consists, switched places for the sim cards - problem still consists.
Started the phone without the SIM cards, boot it up, optimized the apps, tried to insert the sim card again, but ALAS! it still doesn't work.
So now I have a phone that works, but cannot function with a SIM card....
FYI, I am on SW Ver. V20a-SEA-XX
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.
Hi. Having a problem... Phone tries to restart after maybe 1 min. Usage ... But only with sim card installed from certain operator. Other sim doesnt create this issue.
Android 6.0.1. Tried flashing cache. Safe mode. And more. If this sim is in the phone it tries to restart ... But infact fails. Just freezes with lg logo.
Any ideas? Known issue? Or should i simply get a new sim card from the operator?
Hi,
I have a huawei p20 lite dual sim however when I put my mtn sim card into the device it doesnt register on the mtn network it says no service, However if I insert both my work sim and private sim the phone then recognizes my private sim BUT only on edge the mtn-sa comes up but under that it says no service.
If I only put my private sim in then the phones straight away says no service and no matter what I do it still says no service.
I have resetted the network settings,
I have booted the phone in safe mode
I have set the phone back to factory default
I have formatted the partition
But with all this being done I still cant get to work the phone shows my number under dual sim settings though.
I'm really confused and dont know what els to do or try.
I also should add that my phones running EMIU 9.1
