Mobile Network Type- Unknown
Service State- Out of Service
Mobile Network State- Disconnected
My IMEI still shows up and I can connect to WIFI and bluetooth. The only problem is I can't get a signal, not 2G or 3G (even LTE)
This started happening out of nowhere, I tried taking out the sim, factory resetting, wiping caches, changing the APNs, restarting the phone, and I even put the sim in a new phone (It got signal).
If anyone has any ideas I'm all ears! What's the point of this amazing phone if I can't call people with it?
How long did you have the phone before this happened? Did you dial *#*#4636#*#* to check the phone info and change the network type?
I had a similar issue, but I think mine was a lot worse due to a dirty flash. I ended up having to do a fastboot recovery to restore it to factory.

What service are you with? I had this same exact issue a week ago with an LG G2. My Sim card would work in my Nexus 5 but wouldn't work in the G2.
After numerous factory resets I eventually called Metro PCS (my carrier) and I was told that whenever I put my Sim Card into a new phone I must always contact them and give them the new IMEI # so that the phone can work.
The Metro PCS rep claimed that they have a feature that disables the Sim from working in an unauthorized phone. I guess its to help with theft.

Hi, were you able to fix your issue? I am having the same exact issue and have done all troubleshooting I can do on my own but still nothing works.
If you have a method of fixing this please share.

I know this is really OLD!!!!
but i just had the same issue today
with a NEXUS 5 running stock marshmallo 6.0.1 with the latest patches
, and yes... is not the phone is the carrier
MetroPCS do IMEI lookup
i had another phone before the NEXUS 5
so it is no just matter of swapping the SIM card from one phone to the other
you need to call CS and you told them that your phone is not registering on the network
and that you just swapped phones
So they ask you for the IMEI of the "new" phone
and your SIM card #
you reboot your cell
and VOILA!
now the phone registers in the network
Yes, Metro do IMEI authentication
Hi. I have bought a Galaxy S6 Duos yesterday, and flashed XtreStoLite Deo-Mod v2.1 due to battery performance. Everything working just fine but the only thing is that there is no mobile network menu in settings so I can't enable mobile data. I have installed the quick toggle fix by Samsung but still no joy. Searched everywhere on this forum and google, and could not find anyone with my problem.
This is my first Samsung device, so I think maybe I've done something wrong.
Any advice and suggestions are greatly appreciated

Flash stock 5.1.1 ROM via odin to get it working again.
http://www.sammobile.com/firmwares/database/SM-G920F/
what if stock rom does not do the trick, what can be the cause of mobile networks disappearance in the settings?
edit: forgot to mention that phone shows signal bars, and cell info in service mode, and sim card is detected when inserted or removed, but after restart nothing changes (still no sim and no mobile networks menu in settings)
could it be faulty or damaged sim reader?
or blacklisted imei? (phone was bought second hand with knox triped)

After almost a year of trying, different fw, stock and custom, flashing different modems, extensive Octoplus flash, DRK fix, unlock, even writing different certs, which led to IMEI change I started to suspect HW.
Couldn`t find any 3rd party repair shop in Prague where I live to replace SIM reader (was also hearing all kinds of nonsense, like Samsung blocked the phone, or they wanted me to agree that if they broke backpanel glass while opening the phone, that it is not their fault, and I should pay repair if that happens, etc.).
In Samsung service center in Prague, CZ, they were trying to sell me a new motherboard (which costs more than a brand new, unopened phone, secondhand).
So when I went to Croatia during Christmass holidays, I brought the phone with me (at least to use it as a camera ), and while I was ther I went to authorized repair center in Zagreb, to change the SIM reader, but instead I got a brand new motherboard in factory warranty.
Buuuu for Samsung CZ, cheers for Samsung CRO!
I have the 920F model and activated it with a UK sim a few months ago.. Have been using a US sim for the past 2 weeks, but today I went into an area with no service for a bit. Went back into an area with service and suddenly it says 'Not registered on network' when I go to make a call and 'No SIM card'.
I have gone into flight mode, cleaned and checked SIM (not a problem with the card), and then when I went to check the APN settings I noticed there was no way to get into my 'Mobile Network' settings! Its just gone!
Is it possible that it has reverted back to the European region lock and is awaiting a European SIM to be inserted before I can re-insert my US?
If it is a region lock, is there anyway to unlock it without using a European SIM as I no longer have mine and dont have quick access to one either.
Any help is appreciated. Hoping there is an easier fix.
I think airplane mode disables that menu. Did you try to take it out of airplane mode again before looking for the menu?

Yeah, its not in flight mode anymore. I think it might be a region-lock issue but no way of knowing until I can get my hands on a UK sim!

Im currently having the same problem with my 920f. I dont think it is region lovk because i am using mine in the same region that it was produced for. If you have fixed the issue pls tell me how you did it. I also noticed that whenever you connect it to the pc, it is not being recognised.

Mine does connect to my PC. Haven't found a fix though - going round and round with Samsung and they say I have to bring it into a UK Samsung centre but I'm now in the US!
Going crazy!

If you go into your settings, under 'connections' does Mobile Networks appear? Try checking your APN Settings if so.
Has anyone found soution to this issue, and how did you fix it?
I am facing the same issue with my Galaxy S7 Edge (dual Sim) as i was traveling to another country (Europe). My phone is unlocked. I had to reboot in order to get back the "Mobile Networks" option.

Depends on whether your phone has an imei, and whether you have to unlock it.

SN and IMEI is good in about the phone, when dialing *#06#, and in service mode (*#0011#) says IMEI: OK.
As for sw, I don`t see anything that is not good, anymore.
For half a year I am trying to find a solution to this issue, tried almost everything, even writing clean cert.
Last thing I am going to try is sim reader replacement, at the begining of next month, and see if that will help.
any progress on the issue? im having the exact problem,was using it one day and it just started saying 'no sim card' inserted even tho when i put in a sim it says 'sim card added' but right after goes back to saying 'no sim card inserted' , plus the mobile networks option had disappeared from settings. also, mine does not connect to my computer and it charges slow. my technician diagnosed it as either the mother board issue or the usb port and sim card reader issues respectively. will try a factory rest and see if that's any help.
*update* factory reset did not help.
I just upgraded to 6.0.1, canadian G920W8, I put it in airplane mode, I removed airplane mode and the cell network never got back up.
Thoughts?
I was able to get my connectivity back after a factory reset from the recovery partition. I am now afraid to push on "airplane mode" as I fear I will be locked out of service again...
factory reset did not work for me, tried both from recovery and settings, any other solution?
Hello!
I'm having the same problem. Is anyone who tried the software downgrade to lollipop??
I tried both Lolipop and Marshmallow, still the same..
anyone figured this out ? I have exact problem on my sm-g930f.
Can't find a fix to this anywhere
I can't make any calls or connect to 4G. So far I've tried resetting network settings, triple checking my APN settings, I've even got a new sim card but still nothing.
When I make a call it says 'not registered on network'
It won't even let me automatically connect in network operators.
I've even done a full factory reset but that didn't work either
Last week the phone worked fine but now the only thing that works on it is WiFi
Anyone know how to fix?
Where is the phone from?
Not sure too be honest. I bought it on eBay about 6 months ago. It's worked perfectly fine up until now.
Don't understand how it just stopped working. I've even updated it to the latest official firmware.
go to settings --> apps---> show the system apps and go to phone app and clear data of it
go to sim toolkit then and clear the data too if there are more then 1 then do it for all and try to reboot
if that doesnt work
type *#06# and check if u see ur imei
if u dont see it ur ****d up ur efs
Thanks for your reply
It didn't work though. I cleared the data on 3 of the phone apps data & 2 of the sim toolkit.
My imei does show when doing *#06#
When I restart the phone I just get a ? symbol top right. It eventually disappears and I have 2 bars signal but I still can't make any calls, texts or have 4G though
Just to confirm it IS my phone causing the problem as my sim card works fine in my wife's s8 plus. It's not the sim tray either causing the problem as I've tried hers with the same result
Anyone?
I'm desperate for a fix
Many many thanks for all your amazing help ?????????????????

Check if your IMEI is not blacklisted.
Found out it is blacklisted!
Anyone recommend going here

On what network was this phone previously used. The best thing to do is to contact the carrier and try to fix it with them
My understanding is IMEI blacklisted is usually when phone has been reported stolen, it's intended to render the phone unusable on any phone network.
Same
I have the same problem, is there anybody here can help me? Wipe data: done, reintall stock firmware: done, device info app installed and shows sim infomation with signal strength-141 Type lte, but, cell identity 0, lac 0, psc 0.
Wifi It's all right.
Hello guys,
Im coming at you for a question which I can't have any answer.
I bought a Note10 Plus in October to somebody on the web, the phone was brand new (on its original sealing and packaging) and working perfectly. I was first on Three network, the phone worked, then I switch on GoMo, working perfectly too. On the 10th of November I traveled to Japan with a local sim card (Docomo) and same, all working. But yesterday, I came back to Ireland where I live, and still as of today, the phone show me 'SIM 2 not allowed'.
The phone is unlocked, I've checked with the Samsung support and they confirmed it (but didn't bring me helpful troubleshooting steps). I've contacted my carrier too who said that there is no issue on my account, and they will send me a new sim card too.
I'm not expecting it to work though, as the SIM card is working on the iPhone X of my gf, and her sim card is not working on my phone too. So it's only on my Note 10+.
I've tried to remove the sim and reinsert it, restart it, reset network settings, check the date and time, nothing to do, all go to the same error.
After making research, I tried to check some IMEI Blacklist check websites, but I don't trust them as I don't know where these infos comes from, but one catch my attention because it told me that the phone was blacklisted : https://www.imeipro.info/
All the others says that the phone is clean. Again, that's why I don't really trust it, and my carrier didn't mention any block. I'm still curious why my phone appear as blacklisted so I send them an email to try to know more.
I receive signal too, but can't send/receive calls or text, and I don't have access to data neither.
So now I have my phone with no any SIM working, and I don;t know what to try to get my phone working again.
I think I've explained all I did today, I don't know what to do more, I don't have any idea of what's going on with the phone, that's why I need your light to see if you can help me to find a way.
Thank you guys, I hope to hear from you soon!
From the sounds of it, it sounds like it's been blacklisted, that's my guess. Do you get any message when you insert the sim? I had a similar thing happen to me, turned out the guy I bought the phone off on Ebay didn't pay he's bill and phone wouldn't text or make calls anymore. O2 was the company that barred the phone, and they couldn't help me even though I had proof I'd purchased the phone from the guy, only he could sort it out as it was he's account. Anyway thankfully PayPal came to my rescue, they just needed proof it was blacklisted, carphonewarehouse did a check and printed out the results for me thankfully as I knew the guy that worked there. I got a refund and promised myself I'd never buy a phone off Ebay from a personal seller, if its a business account then maybe. Awful experience though. I hope you get this sorted.
I'm guessing you've never rooted the phone or flashed it as that can sometimes delete the efs folder which causes the phone to have no imei.
Thanks for your answer !
No usually I root all my phones but this time I wanted to keep it as normal, because tthe phone looks like there's nothing more to improve to me (except a little bbit the camera when the light is low..)
I didn't knew that it could cause such things ! I should have done that
Honestly that was the first time I bought the phone to somebody, and more of that, the phone was sealed on the original plastic with the label ''eu sim card only''. So I was trusting it, even if I know, that doesn't mean it's safe behind that.
Since I've posted the message, I contacted few carriers, like mine GoMo, and they dont know anything about the blacklisting (I was surprised) then I contacted Three, they told me that the device does not belomg to the; so they can't check.
I tried Eir, and they refused to give me infos for data protections, which I think is stupid because the phone is not a personal information who could reveal an identity but anyway. I didn't though about Carephonewarehouse, I will visit them because it seems like this is the best idea.
The weird thing to me is still that it didnt worked suddenly... I was in the flight and this is when I came back that it didn't worked. Well, maybe that was a bad hazard.
Something I've discovered yesterday more of that is when I have this issue, turning off the 4G and only allowing 3G/2G will allow me to use the data. Still no phone or text, but the phone is detecting the H+ signal and I'm free to go on the web.
Yes for your question, the issue happened instantly when I insert the card on the SIM1 with the error SIM not allowed, the SIM 2 slot works perfectly, that's what I'm using for the moment but I can't use any SD card at the same time, so it bother me. :/
Thanks for sharing your experience, then I know a little bit fore of what to do. I wanted to go to the police but I don't want to spend 2 hours there. Maybe I'll think of it as a last resort...

I just came from Japan as well I had the same problem but with my Sony Xperia 1.
I bought it from the states and I took vacation to Japan and used their sim card.
When I came back here in Florida I switched back to my at&t sim card I couldn't make calls or texts only data works for some reason I tried everything I used sim card on other phones (sim card is fine)
I tried everything, nothing worked !
I factory reset the phone and it worked, fixed the problem (it's strange because I used Galaxy s8 also with that sim card and it's working fine)
My Sony Xperia 1 had similar problem to yours
I don't know if this will help you to be honest but I had kinda same problem.
Hope you solved you issue.

Thank you for that, I've tried this yesterday after a backup, I used the sim card with the phone completly as new (well, I've restored it from the settings, so I don't know if it was the good way) and it didn't worked.
I think I will try carephone warehouse as jadaress1 requested, it might give me lot of infos there. Im also starting thinking that the phone is carrier blocked, but I can't see any reason why the phone was new and already unlocked so I don't see any reasons...
I'll let you know
