Hi guys,
I have a LG Optimus 4x HD with stock rom (Jelly bean). About three weeks ago, I suddenly lost my network connection and it looked like my phone didn't recognize my SIM card. I put my battery and my Sim out and in my phone, but that didn't help. I tried many SIM cards and they work excellent on my other phone. When I turn my device on It just boots up and doesn't ask for my pin code at all. I see no difference when my SIM card is in or out my device. However, it does recognize my SD card, so I think there is a problem with the software? On the lock screen I just see the message ''no service'' and at the top I see this (first pic). When I try to dial someone it says ''reorganization of internal processes. Try it later.''. I read on a forum that I had to go to ''mobile networks'' in settings, but that isn't possible (pic 2).I also tried to put some paper between my sim card and my sim card slot but that didn't work either. Does someone have this problem too or is there somebody who can help me to solve this problem? Your help would be greatly appreciated.

I discovered that my phone doesn't have an IMEI and IMEI SV code anymore. It also doesn't have an baseband version. Do you guys know this caused the lost of my network connection and does anyone know how I can recover my IMEI number? Finally I managed to enter the mobile networks in settings by do a long tap on the data icon in the notification center. I hope someone can help me.
I have the same problem as you. With every restart the phone is unable to read the sim card. Also the baseband is shown as unknown, and I don't have imei no. The solution for me is to remove the battery, and put the phone in the refrigerator for 10 minutes.(yes in the refrigerator The phone is getting very hot when is searching for network and to have it really cool helps apparently. Try it yourself to see if it does the job for you and let us know.

Thanks for your reply! This morning, my phone finally asked for the first time for the sim password and I finally got a signal. I got my IMEI and my baseband number back. Unfortunately, after an hour or so I tried to send a sms and I wasn't able to send it. I got the error no USIM or so. The IMEI and Baseband number disappeared agian. I turned flightmode on and of and I didn't get a signal again... New today was that I am now unable to connect to multiple wifi networks too. Now my WI-FI MAC-adress is 00:00:00:00:00:00. I already lost the phone and I now also lost the smart part of my smartphone... I also tried to put my phone in the refrigerator but sadly it didn't help. I think I have to buy a new phone....

Sorry to say that "It's time to say goodbye"
I got same problem with you and try all kind of possibility. Here is final verdicts:
- Some phone repairers I know said It's the encrypted baseband partition is damaged, unless you have backup of that, it's a no-go
- I've tried to reflash the phone and it will stuck at 10%, you have to push really hard at some point at the back to make is flashable. After that, the signal back on with baseband and IMEI.... but only for a few restarts it will be gone
Hi blbterminator,
I already said goodbye to my p880 (has been replaced for the G3), but thanks for your reply. Now it's clear for me that's it's a hardware issue.
Maybe do you know if this problem only affects the lg p880 or other brands or models too?
Many thanks!

Hi
I just got on at&T 8925, I put in sim card and it did not ask for unlock code, so I guess it is unlocked, I put in my sim card (Fido Canada,works in other phone) and it show "no service" can not find phone network signal.
I tried
ATT ROM 1.57.502.2 and
RUU_Kaiser_ROGERS_WWE_1.83.631.4_radio_sign_22.51.88.13_1.27.15.32R_Test.exe
radio 1.27.12.11 and 1.27.15.32
all same problem.
Can anyone help me, are these rom combinations not good? or something wrong with the device?
or anything I need to do?
thank you for your help !
Try another known-good SIM card. If you still cannot get service, then you probably have a hardware issue with the phone.
Sounds stupid, but did you make sure you put the SIM in the right way around.
You wouldn't believe how many people have not done this right.
Sounds like it's not unlocked... when I got mine it wasn't unlocked but it only asked for a code once.... just run the unlocker to be sure...
maybe to hard reset?
Hi thanks for everyone's help.
I think I put the sim card the right way , otherwise it will show 'no sim card'
I am keep trying other rom/radio; still no luck, it either keep searching or say 'no service'
I really hope it is not hardware problem.
hope if anyone has the experience and could help me
it really confuse me.
Thanks

welll this might be a little solution i read in another thread...sum times the phone will not read the sim becuz its not making enough contact to the phone...so maybe a little piece of paper on top of the sim then put it in the phone MIGHT help..if it doesnt then ur phone is jacked up =P
or
when i put my tmobile sim in my unlocked 8925 it worked and then a couple our couldnt get n e service... and i checked my brothers phone and dad and they didnt have service too... so maybe sumtimes the network will nto work for a while. or sumthing
If you go in the phone options and do a manual network search, does it find anything?
Thanks brian_v3ntura:
but I tried paper, same thing, maybe not be contact problem.
Thanks kilrah:
I tried that, it shows " cannot read setting from network, try viewing setting later or disconnect data connection and try again."
I did saw something online that maybe because the Fido sim card maybe old (about 3 years), but it did work with sth. like Samsung blackjack II. maybe Kaiser is more complicated.
just wonding if anyone have experience that old sim card may have problem with new phones.
I will keeping trying...
My SIM card is about 4 years old.
I'd bet your Kaiser has a hardware problem.
Hi, guys
I tried a friend's Fido sim card, it works, I don't what's the difference, but it is just like that, maybe I should go get a new card.
Thanks everyone.
good
as one of the boys ur sim might be damaged/old (power failure issues most likely)

yeah, just what confused me is that the sim card still work with my other phones.
Hey guys,
Long time lurker here... and I'm having the same problem.
I have a foreign (Cyprus CytaMobile Vodaphone) SIM in my Kaiser. A couple times over the last few days I was getting the "no service" but if I reset (turn on/off) the device it was fine. Today I cannot get service on it at all. I tried it in an unlocked 1G iPhone and it didn't seem to work either.
I thought maybe the SIM is dead, however when the device it's in starts up, it asks me for the PIN set on the SIM card. I enter the PIN, and it unlocks the SIM. How could the SIM be dead if the PIN authenticates? However, when I put my regular Canadian Rogers SIM in, it works fine.
Where it usually says "Searching.." on the home screen, I once got "Denied, searching.." but I haven't been able to reproduce it.
Any ideas? The provider doesn't have a local roaming agreement, however for the past year it has always registered on the network and allowed me to check balance and send text messages.
Is it most likely a dead SIM or blocked by Rogers? I'm doubting the blocked part, but the successful PIN entry is what has me baffled...
Thanks!
Chris
Ok different SIM card also from Cyprus Cytamobile in a SE w810 does the same thing. Is Rogers seriously all of a sudden blocking these? There is no local roaming agreement, however I would always get the Rogers welcome text's and even be able to check balances. I've been doing this off and on for 4 years...
Anyone ever heard of something like this?
Thanks,
Chris
P.S. Sorry, getting a bit off topic but I thought the initial problem was related!
EDIT: Ok, I can also see all the SIM contacts and SMS messages stored on the SIM.

I also have the same problem with my tytn, I have a bad feeling it is hardware If you manage to find the problem please let me know. I have tried the paper thing and also all new firmware and OS nothing helps
Try setting it to GSM only (disable 3G) and see what happens.
To do that go to Settings->Personal->Phone->Band->Network Type=GSM.
If it works then, you might want to read this thread: http://forum.xda-developers.com/showthread.php?t=419803
I bought new TyTN II, and when I insert my sim card, he doesn't recognize it, in the top of the screen is text NO SERVICE. In the start/settings/connesctions/connection setup, there is no my country to select, or my operater. Does the new cooked ROM may solve my problem? Please help...

Does it say no sim card, or just no service. If it doesn't recognize the sim card. then it is probably sim locked. If it recognizes the sim card, but just offers no service, it could just be your connection settings.

Hello,
I didn't want to start a new thread, because this one is somehow connected with my problem
So here it is:
I've been using my phone for about a month, it used to show full network ect. My friend gave me an anthenna for gsm mobiles (well, sometimes it didnt work properly when I was in the basement i.e.) so i tried it. Worked perfectly, except it was sticking out. So i thought that I don't want to use it and disconected it. Since then it shows no service, sometimes "1 dot" in network display. Tried hard reset - didn't work. When i put the anthenna back, it shows full network again.
Please, tell me, what should I try.
Thank you in advance
I seem to recall reading somewhere here that once you put in an external antenna, something gets tripped and the phone will only work with an external antenna from that point on.
Sorry -- don't recall any details. Try searching.
This morning I updated my note to 4.0.4
After updating it suddenly I wasn't able to make any calls or messages. I did some research and I have discovered that my phone had suddenly re-locked itself and is unable to allow my sim to work with it.
After doing more research I have rooted my phone and tried the Galaxy S unlock (which supposedly worked with the Note), and ended up with something like the attached picture. I see random icons but no specific code.
Here's a little background info that may be useful.
I bought this phone over in HK while I was there for vacation. The network lock occured when I first bought the phone but then the store that I bought it from found a way to fix it (without rooting the phone). Even when I upgraded to the OTA ICS there was no problem at all. I don't know why suddenly with this minor update it reset the network settings.
When I look into the mobile networks on my phone's settings a window pops up saying "Insert SIM card: Insert SIM card to access network services".
Which to me was kind of weird since I have inserted my sim into another phone and is able to make phone calls just fine.
Please help me! I have no way of contacting that store that I bought the phone from and I'm in need of getting my phone to work asap.
I am not lazy or anything, I have spent the last few hours trying to figure out how to solve this problem.
I have no experience in flashing a new rom and I really don't intend to do so unless i have no other choice.
Check out here;
http://forum.xda-developers.com/showthread.php?t=1804611
You can - I believe - Downgrade to GB and run the unlock tool mentioned in that thread then upgrade again to your ICS..
Will this help?

Some thing wrong whit the z1?
Have googled hole day cant find a solution plesae help me?
anybody have the same problem?
Cheers Stian
Go via Warranty.
Well same happened to me at first I though was the sim reader but it was the rom that suddenly stop reading the sim and I don't know why. The solution was to flash a different rom and now I am with kitslim. To check the sim reader I used the app "sim card by gsmdev" such app allows to read the sim information like contacts imei etc so if that app reads that info means that the sim reader is OK and you need to flash a different rom or the same. Hope this help
Sent from my C6903 using XDA Premium 4 mobile app

Check if your imei is intact, perhaps you could flash an FTF file which will replace the OS so back everything up first.
Make sure you are inserting the sim correctly (i know you probably are but it's worth checking) ones the sims in the phone it should reboot, could be that the contacts which hold the sim aren't raised enough, don't bother fixing them just take it back if that's the case, if the sim has been inserted incorrectly then theres a chance that the contacts may be bent and if that's the case then your warranty will be void, but in all fairness it sounds like a dodgy phone rather than any of the above.
I'd still do the FTF flash anyway, it's probably the best shot you've got, oh and i've noticed that some peoples phones will read sims and others won't so the fact that it works in yours and not hers although weird, isn't conclusive. Try another sim too.
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, ...

AFAIK too - but without IMEI it could not attach to the network and therefore cannot show carrier name

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
