Hello,
my Xiaomi Mi 9T Pro running on stock MIUI Global 12.5.1.0 (RFKEUXM) can now suddenly not connect to my mobile carrier.
I hope somebody can help me out.
Some facts and stuff I have tried:
The connectivity icon on the top is just grayed out now and shows an X.
But that was not the case in the morning today.
At that time it showed full bars, but not the usual 4G text and the mobile internet did not work. After some attempts written below it is now just gray.
Mobile internet and cell service do not work.
I have rebooted multiple times.
The IMEI for both SIM slots is shown as 0.
No baseband version is shown.
(I am sure that this was also not the case early in the morning.)
I have never installed a custom ROM on this device, bootloader was never unlocked.
The SIM card is correctly inserted and the phone number is shown in the settings for SIM slot 1.
Trying SIM slot 2 (incl. reboot) did not fix the problem.
The SIM status shows that the service is not available, also on the top left when the phone is locked. ("Dienst nicht verfügbar" in German locale.)
Trying the SIM in another phone works, which I think makes it not a carrier problem.
Trying another SIM in my phone also does not work.
I unfortunately had dropped the phone days before, but no damage visible at all (phone case FTW).
Also it worked without problems, which makes me hope this is not hardware related.
WLAN works, so internet connectivity is possible.
Phone is out of warranty.
I did search for other threads with similar issues, but they all seem to be related to having flashed custom ROMs and then losing the IMEI.
Does somebody have any idea how I can fix this?
Thank you!
Edit: I just remembered/saw that I did do the "Xiaomi Service Framework" system app update to version 6.0.6-G yesterday night, maybe that caused the problem? Currently researching on how to roll that back. If somebody knows, please do tell.

Did you check Settings, SIM cards and Mobile networks, SIM 1 (if SIM is in Slot 1)
Do you have Turn on? If Turned Off, then do Turn On
If not, ie if it does not recognize the SIM card, then it looks like a hardware issue
Assuming, as you say, that SIM card is ok, correctly inserted, and that phone runs only the stock firmware - hence no root, no custom ROM, no custom Recovery (that user could possibly wipe partitions), etc
Maybe, some connection got loose and later disconnected completely
Thanks for you answer.
I am sure the SIM is inserted correctly and working. It's been in there probably for years now.
Don't know if you saw my update above about "Xiaomi Service Framework". Checking that right now. Maybe I should just do a factory reset.
What I have noticed now a couple of times is that the phone crashes and reboots, just now happened when I connect for USB debugging or before when trying to enter the SIM pin after a reboot, ...

Agreed, therefore I am sure the SIM is recognized. The phone even shows my number and the SIM has the carrier name.

If the carrier name is recognized, then IMEI cannot be NULL
Very strange
Try to play with Preferred network type setting
Maybe something really got wrong with the updated Framework

Oh, I though the IMEI is device specific and should be there even without a SIM inserted.

AFAIK too - but without IMEI it could not attach to the network and therefore cannot show carrier name
Hence strange, and/or the contradictory descriptions/observations

Ohh, sry there is a misunderstanding.
The carrier name is only shown as the NAME of the SIM card (I guess it is stored on there or the phone has remembered it). But there is NO connection or carrier name shown in the top notification bar.

Yeah but you still have unknown IMEI - that's something that should have not happened
Anyway, go to Preferred Network Type and try with Prefer 4G, Prefer 3G or Prefer 2G - maybe, with the updated Framework, something went wrong with the bands support or so
If it wouldn't help, then I'm out of the ideas how to solve
So I did do a hard reset now, and it worked for a short time (IMEI is back), then it doesn't again, and ... just now again. It really is not stable.
Thx. I will post updates when I know more.
Unfortunately the phone keeps crashing and rebooting when using it. It just freezes and restarts, and sometimes it takes a long time to restart (seems like a crash loop).
Twice I also saw some graphic artifacts (bright magenta and green) on a small part of the screen.
I don't think this is just a mobile network connection problem anymore.
BTW: I have installed an older version of Xiaomi Service Framework (also the hard reset reverted it to a much older version), but that did not help.
Hey!!
I hope you doing great
Did you manage to solve the issue?
@Fawad Hussain
Unfortunately I could not solve it, so I am not able to use the device anymore.
Btw, as far as I can see there is no current smartphone without a notch/punch hole which is not gigantic (ASUS Rog Phone 6).

Same thing happened to me, I have managed to get it thanks to this guy in the video which I don't understand what he is saying but I just followed his steps, so if you are looking for a solution this video is.
But my device is not rooted and bootloader is locked, I tried ways but don't know how to root it or unlock bootloader properly

Hello,
I have problem with SIM card on my phone. I'm using Temasek's CM 10.1, Kowalski kernel, and V20I-EUR-XX baseband. When phone boots, I normally input my PIN, but it doesn't connect to network, I have to go to Mobile networks and Choose operator automatically, then it connects. I can call and send messages normally, but when the call hangs (me or the other side) it says SIM card error (something like that). Also I can't save APN. In APN settings there is nothing, and when I create APN manually, I input everything and press save, but it doesn't stay, APN's remain empty. I use micro-SIM with adapter, because my operator couldn't get me normal SIM at a time. I'm on Croatian provider VIP. Everything normally worked with micro-SIM from Tele-2 provider (although on CM 10, and CM 7, didn't test it on CM 10.1).
Is it related to my SIM card or SW (ROM or baseband)?

Not sure if you read my post, but I think we are having the same issue regarding the APN, etc.
Not been able to solve mine yet, perhaps together we can put out enough info that someone here can offer a solution? I haven't changed the baseband or kernel on their own, only went from stock 2.3.3, to CM10.1, then to CM7.2.
Are you able to remove the SIM PIN? If you remove the SIM PIN from security, are you able to save APN?
Does your phone access data with the native SIM card the phone was originally locked to?

It seems that PIN is already disabled in Settings-Security-SIM card lock settings :silly:
I called my old operator and they told me my phone was sold locked, and new operator told me they can't help because I didn't buy the phone from them. But then how it works now for calls and messages?
I don't have any other SIM with me so I can't test it with my phone. You say going back to CM7 didn't help? I guess I shouldn't try that then.
Maybe flashing stock ICS would? Any other suggestions?

I haven't tried stock ICS yet; maybe it would? I will try that tonight.
Mine shows the SIM PIN on, when I try to change it it asks for my old code, which I don't have of course, so I can't remove the security. Been hoping that someone else would have had experience or knowledge of what would cause the problem and have a solution or suggestion to try. The closest I came was on a different forum about a Sony Ericsson phone, but the rooting and flashing procedures are so much different I couldn't see a solution in it, though they suggested flashing the baseband iirc.
HMMMM, now that I read your reply, I can't say with 100% certainty that the phone was unlocked before I rooted and flashed CM10.1.....I had thought it was but perhaps it wasn't, and we are having a more similar issue than I thought. So the glitch, perhaps, is that it was not unlocked, the custom ROM somehow "half" unlocked it, and here we are stuck.
Okay, my only thought then is to take it back to stock everything, the most up to date I can find, then unlock it with code, and see if I can change the APN at that point. If so, I will root it, use My Back Up Root to save settings including APN (just in case so at least I can restore it that way if I can't do it manually, after)flash CM10.1 again or another fabulous custom ROM which is what I really wanted in the first place
I will try that tonight, and post you the results. Let me know if you have any (better) suggestions as well, I'm up to try almost anything at this point. Was hoping to upgrade to this for my daily phone as I'm limping along with a Acer Liquid MT that has seen better days
If anyone has a link to quickly point me towards the latest stock ROM etc. and wants to post here, I would be much obliged Might save this noob a few hours scratching his head to find what is most certainly in front of my nose already, but I digress...
Cheers
New baseband
I just flashed V30A baseband, and it didn't help. We can cross that from the list.
Well colour me confused...and happy?
I just today picked this project up again, about to attempt a different fix, again...*sigh.
Lo and behold, i insert my sim and power on the phone, and it asks me for network sim unlock.....odd because I'd used the phone with this sim before, through all my other testing, flashed different roms, etc. etc. In fact, I've used the phone on this very package, I know because there are sms messages on the phone from using it. Battery pull, remove sim and check, yup sure enough, old messages there. Hmmm...
Insert sim, reboot, asks for unlock code again. Well, what have I got to lose at this point right? As I said before, I THOUGHT I had unlocked the phone before starting this whole debacle, but wasn't 100% certain about it. Searched my email for the code since I always save them, couldn't find it. Well, in for a penny, in for a pound I suppose. Bought a new unlock code, waited for it to arrive. Input new unlock code, unlock successful!!
Reboot phone....waiting for service....(this seems like forever!!! In reality, less that 60 seconds.) Alas, I have service. And now, just to tempt fate, Apps->settings->wireless & networks->more->mobile networks->access point names..........:fingers-crossed:
I can hardly believe my eyes, there it be, Rogers Internet apn selected. It even auto-detected the damn thing!!
I can offer no further insight, I don't believe I physically did anything to arrive at this remedy. But there you go, for my part at least it's solved.
I have recently managed to install resurrection remix 5.0.2 on my Xperia SP and it works very well except for one major thing, sim card.
When I start my phone I will get a prompt to insert my pin. Nothing wrong here, if I insert incorrect pin I cannot unlock my sim card so it's detected correctly.
After that I will get another prompt to insert a pin, this time it's a little different and the problem with it is it doesn't work. If I input the same pin as I did before it will say "Request for unlocking network wasn't successful" so I can only cancel out of that which will leave my sim card locked.
When I tried to look into settingsI found that "Lock sim card" option was not checked and if I check it, it will ask my to enter my pin which again doesn't work.
I tried setenforce 0 in emulated terminal which did nothing.
Also I looked on internet for this problem with no solution I only remember reading about some script which maybe fixes this issue but I don't know where I saw it or if it actually works.

The script was necessary years ago for a similar problem. Rr502 doesn't need it.
This problem sounds so strange, defectuve hardware could be to blame.
1. Please test your sim in another mobile phone.
If it doesn't work in there too, get a replacement sim from your operator.
2. Start from scratch. Go back to stock rom, test your sim. If it doesn't work then, you have to replace your mainboard. (Get one with unlockable bootloader!)
3. If all your hardware is fine, do ALL stock updates. 207 was the last one as far as I remember. Then, install rr502 again. It should work now.

Thanks for replying. I think I know what the problem is now. My theory is because I installed carrier locked firmware (there were only 2 for my country both carrier locked I guess), my phone locked my network and I had no idea that could happen. So of course I typed in bunch of random codes and wasted all my tries, also had no idea that could happen. That's why I thought It was ROMs fault but it seems that I flashed incorrect firmware and now it's too late. If I go to service menu a go to sim info everything is ok except sim network. And there are 0 tries left. Well now I have different firmware that should work fine with every sim card but phone is locked and the only thing that I learned is if I want to unlock that network it will cost a lot of money. I don't know if there is any other way to unlock it but yeah, it seems that now I'm stuck.

In this case, you definitely need a new mainboard.
There is no hack, no trick, no whatever. New mainboard!
Hi,
I just bought a Mi 9 for my gf as Birthday gift and have a big problem with it.
We use her Simcard from her further phone, which works there without issues, but the Mi 9 just let her use Data on the simcard (internet). No calls or texts in-/ outbound are possible. It always shows that no mobile network is available.
I already readded all APNs (Internet, LTE, GPRS) and tried a couple different network settings (*#*#4636#*#*). I'm not sure why this issue appears and searched allover the internet. Seems like noone else have this problem.
Version is 11.0.2.0(QFAMIXM) with locked bootloader. Could it be that seller flashed something wrong, modem type or whatever? Carrier lock wouldn't let us use the actual sim right? My own sim as well just work with data so it need to be an issue with the phone.
Thanks in advance
Chris
Noone have any idea what the issue could be?
This seems like an operator related issue and probably has nothing to do with the Mi9. Try operator related forums for more help. The only thing that comes to mind is to get a new sim from the operator.

Question:
Does mi9 recognize the SIM Card? Does mi9 ASK for your SIM Card PIN? Or does mi9 say 'no SIM Card installed'?
Hi,
Sim is recognized and contacts shown. Sim pin is deactivated so the Phone don't ask.
Mobile Network is shown and active and data/ internet works. Its just the GPRS funtions (Text, Calls) which don't work. When I try to call I get the "Mobile Network isn't available" message and texts don't sent.
Thanks

The Sim works fine in another phone and my sim which works as well, shows the same errors in the Mi 9. So it must be an phone issue.

What operator do you use? What operators are the respective cards you have tried in the Mi9? Did you buy the phone from a private person and not new in a sealed package? In this case contact the seller.

Do you have 2 simcards installed?
You also might try to reset the modems, howto you can find when searching the forum
Just 1 sim installed. 2nd slot shows the same issues. Will check the forum for modem reset thanks.
Hi,
Weirdly the phone seem to have a Carrier Lock. My gf uses SMART Prepaid here on the Philippines and as said just mobile data was working. Yesterday she switched the SIM for testing to Globe and with this SIM everything works. 4G is available and calls/ texts work as they should.
I'm still confused about this. If the Phone would be carrier locked, should another Carrier SIM not be functional at all? I don't get why Data connections are working then.
For now the solution is to get another SIM. Probably let it unlock in a store.
Regards
Chris
Hello guys. I bought a s21 ultra 9980 512gb.
However, i cant use it with sim card as its not detecting the network. I dont get it what could be the problem. I cant even untick the automatic network search as i get error.
Will post you guys here some photos maybe you can help me out. I dont think is locked because i dont get any message when i insert sim to enter the unlock code. What could be the problem?
Please help. Thx
Are you sure its an active sim card?
Yes. I have the card in an iphone as its my current sim..

Is the Samsung running official FW?
Yes… original .
do you still have the imei number present in the settings and if you type *#06# ?
Might be sim locked by the carrier, you could theoretically still use the esim I believe if it isn't giving you an option to enter an unlock code.
Yes.. both imei show up.
How can i check for sure its sim locked?
Also, when i insert any sim, for one second the “no signal sign” near the battery goes away then comes back instant.. and it doesnt ask for any pin…
Thanks for your inputs
I have read about this issue before as well. Is this a "dual sim" model? Try the other slot if it is, and also try leaving the sim in and rebooting. You could also try "reset network settings" under settings. I'll have a look to see if I can find the thread where people said they had a fix.
is it yours from brand new? and have you checked to see if it black listed? also, there seems to be an issue with some Samsung where they are forced into airplane mode the only way you see this is the notification panel the airplane model toggle is half-lit blue I could be something to do with that. Failing that it could also be if you have dropped the device the ribbon may have come loose as this is a common issue with Samsung a range and that's all I'm seeming to fix lately
Hello. No, didnt buy new. I got it used.Yes its dual sim model. It doesnt appear as blacklisted.
Its not in airplane mode for sure. Also i did factory reset and also wrote all stock firmware ap cm bl csc from samfirmware..but its the same as before.
Also, esim doesnt show up under the sim card manager.
try *#2263#* to change bands, or *#0011#
Maybe also try to put the sim in the other slot, and see what happens. If all the same, try someone elses SIM card for a minute to see. Maybe your sim has become slightly damaged but your iphone still manages to read it, while for some reason the s21 is not managing.
Just tried the sim in my sisters s20 and works. Also tried her sim into this new phone and same . Even if i put in sim1 or sim2.

"In Settings go to network mode and set this to 3G only. Then restart your phone. This works in my case."
Thanks for your sugestion. But its the same…
I had the same issue on single sim korean unit...but factory reset resolved the issue. Actually i used to disable carrier apps which was causing this issue.
Hey everyone. I bought a Mi 11 Ultra from china but I don't know why isn't getting signal at all. It detects the SIM but it doesn't let me make or receive calls neither messages, and obviously it doesn't connect to mobile networks. Can somebody help please?
Where are you, what network are you trying to use and have you got some screenshots of your network and SIM settings?
Hey, thanks for answering! Im in Mexico and about the network, any of them. I thought of changing the ROM from the CN to the global one to see if that help, but I need the mobile data to unlock the bootloader, and since the phone isn't getting signal, I cant do that.
P. S. Sorry, what do you mean by SIM settings?
Attached are screenshot of my SIM settings. Yours will be similar. Make sure your apn is set correctly. Make sure your SIM is recognised. Just basic setting checks. May be try other sim slot and of course, make sure it's right way up for either slot.
Without any screenshot I cannot see what may be wrong, so start again with SIM. Shiny side outwards and make sure it is recognised.
Hi again. Yeah, I have tried with both slots for the Sim, each one the correct way, but is the same result for both of them. Thanks for the example of the SIM settings, now I attach mine. As you may see, the SIM is getting recognized, just don't know why isn't getting signal. I've also tried with other company's SIMs, but I get no different result.
Looks good. I think you need to try with another SIM on different network and same. Try this SIM in different phone as it looks all good on screenshot but may be provider has not enabled it properly. If different network SIM known to be working doesn't work in your it must be hardware, hopefully not .
Also look at settings, all specs. Check SIM status and press 5 times on memory for deep phone info.
Hello and thank you again! Yeah... I've tried different SIM from different companys, all of them known to be working, but none of them has worked on this phone. I'm starting to lose hope... But here are the other settings, just to make sure isn't about software
The screenshot show that your radio is off. This is saying that your phone SIM is not turned on for some reason.
There is not much anyone remotely can do, if you are unable to get it turned on.
Maybe someone else has an idea? If not, and it cannot be resolved by resetting the mobile network ( in settings somewhere) or phone reset, then it may be back to seller as a hardware fault. Sorry I can't help. Let's hope someone else can?
Thanks a lot for your effort. Since you told me that the problem could be the hardware, I asked the seller about this issue and he told me that this problem is covered by the warranty, so I'll send the phone back to them. Again thanks a lot for answering!!
Just for info have you seen this thread about att? https://forum.xda-developers.com/t/not-a-recognized-device-by-att.4462649/#post-87088003
No, I hadn't heard about that, but still, I wouldn't hesitate on changing my provider if another one works, but since I tried changing to another provider SIM and nothing happened, I guess it was a hardware problem. Thanks a lot for the info!
Try doing manual search of network. If it shows nothing then try checking network frequencies of your network provider and comparing them with this phone supported frequencies. Sometimes its due to your network provider doesn't operate the frequency which this phone supports.

thats an easy fix, modem partition needs to be reflashed and configured via code
