Mi 9 network/wifi stability issue - Xiaomi Mi 9 Questions & Answers

Hello everyone,
I just got my phone back from after sales service due to my phone been softbricked (black screen, device not charging when plugged, ...) and by phone can boot now but it's bugging as soon as i put a SIM CARD in it.
When putting the SIM CAR in, phone is loosing wifi connection every 60 seconds (approximately) even right beside the router, and for the network, i'm stuck in EDGE and no signal stability either.
It's the same SIM CARD that was in before i sent it for repair, so the issue should not come from it (and it's working fine on my old Mi5)
One change they did is that they've updated the rom to the last MIUI 12 EEA stable rom, it was still on MIUI 11 global when i've sent it.
I've already wiped it and installed again the last update but it didn't work.
I was wondering if the issue was not coming from the EEA rom instead of the global rom, but i'm unable to install it since i don't have a computer anymore that i can use for xiaomitoolV2 and since it's still under warranty i would like to avoid unlocking it.
Is this kind of issue known ? could it be only software issue ?
Thank you for your help.

I didn't install any specific app that could have modified the settings and no specific app or setup is usually required with my network provider.

More than likely it's going to be software issues. Did you already any apps top modify system settings?

Weird Nokia 8 sim-problem.

Sorry if this kind of problem has come up before, but I couldn't find anything similar to this so I decided to ask you guys if you have seen this before.
So, my problem started out of nowhere, my Nokia 8 (TA-1004) lost wifi and mobile data. I can't connect to wifi anymore and I have no service.
So here comes the weird part. My sim works in every other phone I've tested it, it just doesn't work in mine, AND every other sim card I've tested in my phone
works fine. My sim also blocks my wifi somehow, if it's inserted, it keeps turning off my phone's wifi, no matter how many times I keep turning it on. If I take
sim out, wifi works fine.
I forgot to mention that when this first occurred, I managed to get it work by turning on my phone with my brother's sim inserted, then switching his sim to mine without turning the phone off.
If I turned it off, the problem came back. Now, after Oreo 8.1 update and new sim-card, even this method doesn't work. Nothing has worked since.
Here's what I've done:
-Got new sim-card
-Factory reset through settings
-Wipe data/factory reset through recovery
-I called my operator, they didn't know what the problem is. They recommended to send my phone to manufacturer, but I hope it doesn't come to that. And maybe they
would try their sims in my phone and they would think there is no problem so no need to do anything.
Any help is highly appreciated, thanks
This is very strange problem. Only thing that comes to my mind as a solution is choosing the network by yourself
Sent from my TA-1012 using XDA Labs
I can't change any mobile network settings, because my sim card is detected only for a few seconds and then it's not, so it keeps turning it on and off.
Now I've tried my phone with two sim cards, my brother's (which worked fine on its own) and mine, and turns out that with my sim the other sim doesn't work either.
Same problem here...
every sim card works on the nokia 8 except the one that needs to work...
every other telephone works fine with said sim...
It is a complete new phone so we never tried it with an earlier version than android 8.1
Same problem here, I'm not sure if I downgrade the phone to 7.1 will it work again
Hello,
I have quite similar problem with my phone apart the fact that it was working perfectly with data until I receive Android Oreo 8.1 update (security update 1st Mai 2018). Since this upgrade data doesn't work with my SIM into Slot 1.
When I use the same SIM into slot 2 (hybrid slot that normally contains my memory card) then Data is back.
Do you have the same on your phone?
PS : I've contacted Nokia and their answer is : We have a lot of users reporting this, we are working on it.... I'm miss my old samsung S5....at least the updates were tested before release.
Nokia hotspot failed
I have the similar problem as I've changed the service provider. The new service has 50GB data volume. When turned the hotspot on for wifi sharing with my family, this function did not work but it was showing other devices had connected to the Nokia 8 but unable to use the wifi sharing. Therefore, I inserted the new 50GB sim to my daughter's iPhone 6 and it was running well when turned the iPhone 6 hotspot on. i.e. the sim card got nothing wrong. I did ask Nokia support and they did not find any issues on my Nokia 8. I reckon that must be the phone software / firmware problem as I could share the wifi for my family before I switched to the new service provider. Hope Nokia fix up this issue when they launch the new update. I feel depressed on this brand. I'd been using iPhones & Google Nexus 5 were running perfectly except Nokia.

Hey there,
I'm having the cellular connection dropping out 80% of the time and then coming back on randomly 20% of the time since the latest beta update (build 00WW_5_110_SP01).
I asked to revert back to the latest stable build OTA several days ago and still no notification.

Xiaomi Redmi Note 3 using Nitrogen Kernel v 3.10.107. Sim is no longer recognised

Bought the phone second hand last year as a temporary stop gap until new one arrived from China. Nitrogen had been installed by the previous owner - I have no experience of modding/installing new op sys.
All had been well up to yesterday when I noticed I was getting no signal, no texts no data etc. Checked with mobile operator who asked if I'd tried the sim in another phone and lo and behold it worked in my new phone
From my limited knowledge I think that if I reset the phone to factory settings, to see if that solves the problem, I'm going to get Xiaomi's OS instead when it restarts.
So where should I look for a new compatible version of Nitrogen and, if I download it, will it automatically replace the previous version and leave everything else intact or is it a case of wiping everything and starting again ?
Thanks in advance for any light you can shed ?

Mi 8 - No SIM/WIFI, random reboots

Hello there
Long story short, I updated my Mi 8 (Global Version) to MIUI 11.0.1.0 before the update got suspended. A few weeks ago, my network provider had some technical difficulties, so I lost the signal a few times throughout the day.
A few days later it happened again, even though my provider fixed everything.
But this time I also lost my WiFi connection and I didn't get it back to work.
After rebooting, my SIM did not get recognized and my phone didn't want to connect to the WiFi network
After rebooting it over and over again for like 10mins, everything worked again.
But this issue occured every day since then.
A few days ago I updated my phone to MIUI 11.0.3.0 and the issue was gone for a day or two.
But now I am experiencing those things again, but this time it usually takes a few seconds and the sim activation service starts again and everything works fine for the next few hours until it happens again.
I will provide a full log later, hopefully someone can figure something out.
I really don't know whether it's a software or hardware issue, but losing signal and WiFi like every hour is driving me crazy and I'd like to avoid resetting my phone....
Oh and by the way, I don't have TWRP installed and it's not rooted or anything else.
Hi,
With me it happened exactly the same, I already paid to solve it and nobody has done it until now. I already lost hope of ever being able to repair
I've been having the same problem.
It's been incredibly frustrating.
[Update:] I went to a local repair shop, it's a hardware related issue.
For everyone else having this issue, try the USSD Code *#06#
If you receive an error, your Baseband Chip may be broken.
At least that's what I was told.
I have unknown baseband, did you replace the baseband chip?
if I put *#06# (no sim card in phone) it just shows up blank white pop-up with label IMEI, but no IMEI number or numbers or nothing else.
Mi8 no signal SIM/WIFI
Hello again
Same problem to my Mi8
When I tap *#06# show my MEID, IMEI1 and IMEI 2
Did you solve the problem ?!
Good morning. I have an MI8 MIUI 11, when I insert the SIM it recognizes it and disconnects itself constantly, the connection is not stable, when I turn on the wifi with the SIM on, the wifi is constantly disconnected and at times the wifi does not turn on, at some point too only the computer was restarted. When I take out the SIM the wifi works stable and well. Any idea of the problem ?? soft or hard? A technician told me that the problem is the display module, but they tested it without the SIM so I calculate that it is not the issue.
Yes, Hardware problem
Confirmed the problem is the baseband, but this cell phone model has the baseband integrated in the SoC (CPU, GPU, NPU and Ram) all one, it seems that it is a soldering problem

Mi 8 Connectivity Issues across ROMs

So my phone's been having problems of being unable to detect my sim and at times unable to find my wifi, sometimes refusing to even let the switch toggle on. This was on a locked phone with no modifications on my end, updated to MIUI 11. Since then I've unlocked the bootloader, formatted and wiped the relevant stuff, gone to a different ROM, and then to Xiaomi.eu, still got the same problem. Any ideas as to what's going on, it's unusable at the moment.

Sim card is visible but constantly No service

Good day, everyone.
I decided to ask for help because I cannot find any solution here and I'm out of ideas myself.
Three days ago my signal strength began to fluctuate. From full 4G to No Service, several times per hour, and eventually it stopped there. Sim card is visible but all I've got is No Service. I opened the phone and checked for possible damage but found nothing.
Thinking that it may be something software related I have installed Beast OS (sweet ROM, btw). That didn't help with signal problem. Still No Service. I've made clean flash from recovery several times, and tried different firmware versions but still no luck. Today I flashed MIUI Global 11.0.2 via flashboot but that didn't help either. Oh, yeah. One more thing that may or may not give you a hint. When I used *#*#4636#*#* while on Beast OS I couldn't turn radio on. I can do that now on stock ROM but it doesn't help either.
Please, if anyone has an idea of what can I do, let me know before I give up on this otherwise really good phone.
Just to clarify, microSD card works just fine but SIM card put in the same slot still has that connectivity problem.
