Question Suddenly "No SIM / No network" - OnePlus Nord CE 5G

Hey all, today at 3 P.M. my SIM cards suddenly stopped working. I tried to reinsert and clean them, but no success.. Even with 1 SIM card and rebooting my phone don't helped.
I even read somewhere, that you can try to push gently front and back glass near the SIM card slot together, but the problem persist.
Does anyone know what else I can do? SIM cards are working in my second phone

As cleaning and rebooting were not succesful and the SIM cards are working in another phone, defective hardware is the most likely (and unwanted) reason, especially when the problem suddenly occured. While both SIMs are affected, it must be a controller chip on the mainboard.

I have somewhat the same problem, and it started around the same time. The simcard disconnects randomly at times, while at other times it works perfectly.
I can't distinguish a pattern in when it works and when it doesn't. Sometimes an airplane mode turn on and off works, other times it does not.
Got a new simcard, didn't solve it.
Read about at least one other user experiencing the same problem on a local Dutch forum.

@Sony make.believe
Which carrier do you have? My problems exist mainly with KPN, a Dutch carrier.
On Tweakers the suspicion is that the problem arises when switching between 4G and 5G. When I set the sim to not use 5G I don't have this problem.

Same problem.
Turned 5G off and the problem continues.
Any idea?

out of the box s6 edge cant hear caller!

I was so happy to learn that my brand new phone did not have any screen rotation issue and I updated ASAP so I would avoid that.
so I recieve a call from my wifem and...I cant hear her!!!!!!!!!!!!!!!!
speaker works fine, no bluetooth connected, I have diabled everthing from blutooth to hd calling, to popping out sim card to factory reset, davik cache...low battery mode, I am stressed out..I cant use my old s4 as a phone now and Im am tired of thinkering with this new phone that is broken.... after reading about so many crappy stories and having had an s3 note 3 s4 now a edge s6..I am totally stressed out.
I dont see anyone else experiencing this..I guess I am off to the store tomorrow..
sigh............................!!!!!!!!! wasted hours trying to correct it
factory reset is what i would try
What version are you?
I am on the latest update. ( on general thread marked june 2nd update, I compared it and its the latest one as I got an update as soon as I started the phone.
I factory restored 3 times, the high def. call, on - off, google now "okay google" off
repeatedly pushed speaker on/off, was never hooked up to bluetooth but did that and tried on and off, plugged headphone in and out like 5 times....sigh ..
was loving it SO much until I noticed it was having this handset problem, if my wife hadnt called me I would have not known til today..
funny thing is my retailer told me that these phones are having LOTS of problems...I told them well not the gold ones and hopefully mines from vietnam not china....
I didnt have the screen rotation problem, I dont use it anyways. I almost feel like the retailer jinx'd me...
was LOVING the gold....

Weird problem after updating my Note5 Duos . HELP !!

Hey you guys. Hope you all are doing well. The solution of the problem which is seek is that after updating my perfect note 5 to latest firmware AOJ5 , i cannot save the selection of mobile data to SIM 2 , instead of SIM 1 (under sim card manager)whenever i restart my phone. Because of this stupid Bug, i dont know whether to reinstall firmware or not. So any solution to this?
Plus, the USB driver on smart switch is acting crazy as it is hanging my windows 10 pro. So i am unable to reinstall my firmare as well

Mi A2 bootloap and fix

I'm have very bad problem, after march security update, my phone goes in bootloop(screen freez), but i have luck, oem onlock, and after bootloop i'm unlock bootloader, and crytical particion, but my luck goes to end. I can't flash fastboot rom, after 15x time flashed, 2 time after 20 times of flashed, 2 times was successful, but did not want to lift the system to the end, and it was constantly getting back to the beginning on boolocker unlock screen and on android one logos, once it was upgraded, but wi-fi and sim cards did not work and very slow work(last update). I have tried all possible combinations, and nothing is left, 95% of the cases flush the rom without end time goes 800sec+.... What i can do?

Okay, i had this problem! I know there is no logic behind the solution I'll offer you(or maybe there is, i just don't know about it). I faced the bootloop issue after updating the security patch of may. i came across a post on the mi forums! Someone said to install the update then before hitting that restart option, you are to eject your sim card! It should work as intended! Then when phone updates, reinsert the sim card! Trust me! It worked for me!!

Missing HSPA/LTE bands on 5803?

With the recent official Lineage build for Z3C, I imported a cheap 5803 from Hong Kong to play around with. Installed Lineage, and noticed I was only getting an Edge connection on T-Mobile. Re-installed a "stock" ROM via Flashtool/Xperifirm, and the problem persisted. I've had two 5803's in the past, with the same carrier, and had no problems with the data connection. Going into the "Configuration" service menu, I looked at the available bands, and it seems like lots are missing (basing my expectations on FrequencyCheck). Am I confused, or is there something wrong/different with this phone?

Service Info > Model Info shows D5803?
That's the confusing thing, the settings do show model D5803. After searching the forums more, I found another thread from a user that has a similar problem: https://forum.xda-developers.com/z3/help/d6603-brand-device-basebands-missing-t3316118 -- phone flashed with a different model firmware. I guess the person I bought from was dodgy.
The only thing I can think of is:
in the compartment where the SIM card is, there is a white plastic slip that you can pull out. It will have the model number on it. Mine specifically says "Model: D5803". You have to pull the strip almost all the way out to read it.
I recommend using a pin to pull it out. There's a little hole/slit that you can poke the pin through. Do it slowly and avoid pulling the slip all the way out, as I suspect it would be difficult to slide back in if you pull it out too far.

Xiaomi Mi 8 - No WiFi, no GPS, but LTE works

Hello,
Sharing my problem by order of events:
Phone falls, screen cracks, LCD doesn't work
Sent to shop for repair
Brought the phone home, but noticed phones WiFi didn't work. Restored didn't work.
Decided to clean and flash phone (used miflash, running clean all script as seen here on the forum) after unlocking the device. Didn't work either.
Tried muktiple ROMs. Same thing. WiFi and GPS don't work. Only LTE.
Any ideas? Is this really a hardware issue? If so, how could it be solved?
Thanks

I also changed the battery. After battery change my wifi and gps are not working.
I think the antenna connections are not in contact with the motherboard after the repair.
