(SOLVED)
Hello,
recently, my O2 sgs will only stay on "emergency calls only" in all different areas where it used to have signal before. I've tried to manually select the network and even though O2 is available, it doesn't connect (register) with it and says "unable to connect, try again later"
tried many different roms, differend modems, but no luck. fed up.
can anyone help me please?

i've told that i already tried many different roms (cm, ezbase, miui...) and modems
I had the same problem with CM7 before after installing if GApps (Google Apps = Market, GMail, Youtube,...). Then I booted into recovery, wiped cache and Dalvik Cache (didn't help) and finally I chose 'fix permissions'. Now everythings is okay again.

have tried, but still it stays on "emergency calls only". what's weird is that it even doesn't call any emergency numbers (says out of service area)...
desperately need help with this, or should i just give it back to the o2 shop... android is the biggest pain...
But the SIM is inserted correctly? Have you tried another SIM? Maybe your SIM-card is defect.
ok, i had another t-mobile sim in my phone and it is working ok. but the o2-sim will not connect, even though it works on other phones well.
what's wrong???

Call O2 and ask vor a new sim because this one probably is damaged.
They'll send u a new SIM for free. I had a similar problem with a dual sim of t-mobile.
Is your phone SIM- or netlocked?
same problem here....suddenly it went emergency call only.have to reset and only then can get the signal back.it really pain in the neck
Mine is GT-i9100 btw
I think my N7000 is broken. Since a couple of days I cannot make or receive phone calls with my SIM card from the carrier 3 (Three Sweden). I've tried two different SIM cards from 3 but it's the same problem. Data traffic still works though since I can surf the Internet without problem. When trying to make a phone call it immediately hangs up, and if I try to make a call to the phone it's unreachable. My phone is unbranded/unlocked BTW.
I've tested with SIM cards from two other carriers and they both work.
The only think I can think of is that 3G voice calls are somehow broken on my N7000. My carrier only supports 3G and maybe that's what's broken... what do you think? (the other cards I tested also supports 2G and maybe that's the reason they worked, but I'm not sure).

I think your issue is the same as mine, though to clarify my issue somewhat:
When the phone does this and I try to make a call it doesn't hang up, it kinds of gets stuck and keeps waiting for the back-end to respond. Similarly, trying to send or receive SMS messages doesn't work either. Rebooting fixes this, though it may happen again quite soon or it may take several days to happen again.
I think it is some background-process related to radio operation getting stuck, though I cannot say what causes it. Factory reset and even full reformat and reset had no effect.
I hope ICS fixes the issue.
What I've tried so far is:
Full wipe - No change
Next step will be to visit my carrier store downtown and test yet another SIM card from them. If that doesn't work I guess I'll have to get it repaired.
Oh yes... I tried another card from another carrier (Telenor) and changed Network Mode from "GSM/WCDMA (Auto mode)" to "WCDMA only" and it still worked. So now I'm not sure why it doesn't work on Tre ?!?

Update: Got a new SIM card from Three but unfortunately it didn't help. Tomorrow I'll send my phone to get repaired :-(

i got the same problem but is t mobile uk, "Data traffic still works though since I can surf the Internet without problem. When trying to make a phone call it immediately hangs up" I tried others sim vodafone, o2 both work without problem.
Factory reset, different stock roms no help...
Yep, same here. I just downgraded to KK4 stock ROM using Odin and it still didn't help.
Cannot send/receive SMS either.

I have a similar issue, some times i cant call and receaved calls ends few seconds after hanging up.

i give up, i changed the network providers to 3 network everythings back to normal.
I can't find the link right now but I read somewhere that there's a hidden area on the phone where IMEI and other carries specific information is stored. As I understand that area is not restored when flashing ROMs. Maybe there's a chance that area has been corrupted??
Brgds... /Tubgirl
In my case , I cannot receive call - I believe it is software issue.
Is there any workaround how to fix it ?

Have you checked that your IMEI is fine (matches the one in the box or the one below the battery)?
i doubt its software issue, i also thought that i was having a software issue, after so many roms that i tried flashing, same result. stock or customized. I went to samsung service center and they had it tested, replaced the board that has to do with the antenna, and now everything is working properly.
same issue i have checked imei with the box and it ok, i can connect to 3G but can't make call only emergency call.
tried CSC Change
Galaxy Sim Unlocker and all unlocked
Base Band and Firmware on XXLSZ
the phone is british in italy
HELP THZ
i have found a solution, set the date 2 months before and reboot. i can make call

Have you guys already tried to use your sims in someone else's phone? Could it be that you have data only plans? Those plans do no allow phone calls even if the device itself can make calls.

Well my case is a bit more complicated.... when i try to dial a number it just black screen and then a popup "Not registered on network" any solution?
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.

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.

Hi
I have Note 9 960N device converted to 960F/DS Dual through software. It was all working well untill it give me "Moisture Detected" warning.
I took it to Repair shop and they dried it and it started well. No hardware was touched.
After I inserted my sim it gave me 4G+ signal and data was working properly.
Then I noticed that I couldn't place any calls nor can I receive calls while LTE/3G/2G option is selected.
I can get and place calls while on 2G mode also Edge data is working.
I got in contact with repairman and they said it is software issue and NVM needs to be reset. I had him reflash the rom and even IMEI repaired/changed but the problem remains the same.
Can anyone please guide me in correct direction or diagnose that what actually could be the problem with my device?
I am not a pro in mobile flashing etc but I understand the terminalogy as am a software enginner and can perform rooting or rom instalation, so your valuable input will be welcomed to guide me in correct direction.
Thanks
anyone here?
