SIM Card Not Detected / IMEI Missing - Samsung Galaxy S7 Edge Questions and Answers

My friend's S7 Edge Duos (G935FD) has been having sporadic service issues for the past few days. This morning, the phone lost service entirely, and now no longer detects a SIM card at, in either slot (the SIM card works in other phones, so its not an issue with the SIM itself). Even weirder, no IMEI information shows up for either slot. Any suggestions?

My SM-G935FD has got the same issue and I need help
I have not found any solution so far !!!!

[Q] Note 3 N9005 Not registered on the network! This is weird! Please help :)

Dear All,
Trust this finds you well
I have this very unusual problem. I have a Galaxy Note 3 N9005 and I live in Denmark. I havent have any problem with the network what so ever. 4 Days ago, I suddenly realized that I cant make any calls and I get "Not registered on the network". Although I can not make/receive calls, the data seems to be working (3g). I tried other sim cards on the phone and they work perfectly. My sim card also works with any other phone!! I did everything I could find on forums (from flashing new roms to....). I went to Telia store ( Telia is the company I get the network), they tried to reset my number and my sim card, tried new sim cards... but it just doesnt work!! They told me that they havent seen anything like this before. Looks like my phone is blocked on Telia Network!! No Telia sim cards works on my phone but others do!
I have tried new modems, firmwares and etc. The phone is unlocked. Right now I have flashed X-note but its still the same. No matter what Rom (custom or stock) I use, it just doesnt work. Can anyone please help me?? Much appreciated!
Hello, i got exactly the same problem here, i was thinking that the problem was about region lock but in fact it's not.
I tried everything like you, flashing modem, stock rom, custom rom... everything i found on the web and nothing worked for me.... I bought the SM-n9005 1 month ago in france, and now i live in new caledonia, i was able to make call for about 2 weeks without any problem and suddenly, impossible to connect the network. Samsung gived me the region unlock code but didn't make my network work again.
I'm so disapointed. My imei and baseband are correct.
bootlader : N9005XXUGNG1
baseband : N9005XXUGNG1
PDA : N9005DXUGNH1
CRC : N9005ITVGNG1 (audax rom)
Please someone help us !
Hello @yashironc
The interesting thing is that my phone is also from France! I have been using the phone for 6 months and no problem at all! The problem suddenly appeared few days ago. I'm actually considering to change my network provider as it appears to be working on any other one! Hope it will not be the same after some time...
please someone help us
Tried This
one thing can tried is changing the imei number, to a phone thats not connected to a telias network that way it will registered on the network another new phone it looks like your phone got blocked by your carrier
Try this.. It worked for me for my note 2...
Hi I faced the same kind of issue with my note 2 and I found some solution.
1. Download the previous version of firmware from sammobile. ( Eg: If the current version is 4.4.2 you have to download 4.3).
2. Flash the firmware using Odin.
3. After flashing the firmware now update the firmware to current one using Samsung kies.
4. After the updation when the phone reboots your issue may get resolved.
It worked for me. Just try doing that......

Thanks Rafi. I tried this but it didnt work out because when I connect to Kies, it says that I'm using the latest firmware which is strange! Looks like in Denmark, the updates are a bit late. I will try to change my IMEI number, hope it works...

Yes, may be your phone has been blacked list by Telia network. Ask your Telia network to be sure?
But curiously, how can you change the IMEI?
same problem here after afligt
Hi, i don't know if changing Imei will fix the problem because my carrier don't blacklist phone and I have the same problem here :/ I got now a phone who can't make call. Damn Samsung 700 € for that ?

Thanks vndnguyen for your reply. I asked them several times but seems like they havent blocked my phone!! They were in shock like me I finally decided to change my network provider as it was the cheapest and easiest solution. I think if the IMEI number is blocked, I should not be able to receive signal from other providers as well, cause that doesnt make sense in terms of security. Hopefully someone could find the answer to this unusual problem and save some lives Cheers!

Nope, if your imei was blocked, you still can receive signal from your home network, but you can not make a calls.

There is a difference between the two IMEI blacklists.
One is Provider-based. Meaning your provider can block your IMEI on their network alone. Other providers work without issue. They used to do this here for a long time if you used a different device than the phone you purchased from them. It still happens in some countries if the device is from another country or sometimes when it runs a customROM.
Providers are also very good at denying this.
The other is the international blacklist. This one renders a phone completely useless worldwide, and is usually reserved for stolen devices.

Hi,
To identify if it's a SIM problem you have to insert that SIM into another phone and see if it's working. Have you tried this?

Humm.. that's not a problem of my SIM, cause it works in my actual iPhone and in my old S4. but thanks anyway
I've unlocked the S5 by cellunlocker.net and they say that maybe it's a problem of IMEI with my actual carrier. But i can't reach them to confirm that
Is there any other way to check my IMEI?
You should reflash in odin flash. Flash the stock rom or a custom rom. I had the same problem on my s5 when i flashed a custom rom l. I flashed in odin and it fixed the imei

Galaxy A5 Duos unlock

I had purchased a sim free unlocked phone in india I started using my local Indian SIM, and it worked fine without any problem I had travelled to Australia, I tried to insert my Australia SIM, it asks me for a sim network unlock pin Can you guys help me please? I am really lost here. Awaiting your reply at the earliest.
Hi there!
Sorry for responding to this late, hope ur still reading this.
I don't think your phone is unlocked judging from your problem. However, you can try unlocking your phone again. There are many sites that unlock your phone for you for $10-$15.
Below is a video that shows you how to unlock a LG G3. The same method is for the Samsung Galaxy A5.

Interchange the sims

Really it's the fantastic rom and I'm using for the past 6 months. No issues. Battery back up super.

To solve calls option disabled please don't use jio sim at the time of installing the ROM.
If used remove the sum and insert it in the second slot. Problem solved for me in my zuk z1.

Bro I tried everything but nothing works. Even if the network shows up we are unable tp receive call. When i tried calling it showed mobile network not available. but there was full network instead. And when i called myself from other number the ring was going on other phone. But it showed nothing in my phone. And sometimes the message randomly comes that you had a miss call. I guess there is some serious issue regarding network. Hope anyone can solve this bug ASAP. Ty

The same problem for me also. Please remove jio sim at the time of installation. Or try to install without sim cards and configure through wi-fi. I've tired by repeating the same reply. Please see the attached screen shot for proof.
Sorry bro i didn't checked. Yes u are ri8 hdr mode not working it hangs up when we click photo in hdr mode. and actually i hav no issue for that as i don't use hdr mode.
#edited
balaji but are you ablr to receive the call or make a call? And is it necessary that i should hav both sim cards inserted? and is Internet working properly?
I'm using Zuk z1 worst mobile for around 6 months yet I doesn't got single update.
Today I called customer service for volte update support.
He told me Zuk z1 never get any update as CyanogenMod shutdown.
So guy here is my doubt I'm using many custom ROMs but no ROM provide volte support.
If the issue is with software than why don't the custom ROM developers can't implement it.
My mobile is sucking me after continuous Jio usage.
I have another mobile Lenovo k4 note when I see signal status it is -83
Where as at place Zuk z1 shows -120
Signal strength sucks

S10+ Live Demo Units have network capabilities. I think.

Ok so this is weird(I think)
Ok so I acquired an S10 LDU and firstly to clear up any confusion, my father owns a retail store that sells mobile phones. We got in Galaxy S10 LDU’s from the network supplier that we provide in store.
I study computer science so naturally I’m intrigued by new phones and decided to have a closer look.
I wanted to test out the in Display fingerprint sensor so proceeded to flash to phone.(LDU’s prevent using screen lock features). It took some time but eventually I got the device to flash. It’s now running the stock firmware for G975F/DS. (I installed dual sim by accident but anyway.)
So this is where things get weird, it sais put in SIM so I just said why not. Then it detects the SIM card and can read the phone number of it. I proceed to checking baseband and it seems to have one(going by the software). So now I’m confused?
Is it possible that there is no baseband and it only shows it because I flashed a firmware on it(I flashed the BL, AP, CSC and the fourth one, can’t remember the name.) Seeing as one of these tar files is for the modem could it of just installed the baseband version on the device without there actually being any basebands/network capabilities on the phone?
The same way that it shows dual sims even though the phone is single sim?
OR
Did Samsung include basebands in its demo units?
Is there any concrete way I can check this without having to take the phone apart?
For anyone wondering the IMEI’s show 0000000000
Very interesting, people in other posts also reported funny things going on w/Odin flashes. Some sort of a software mismatch.
I have a demo version of the s10 + and like you flashed the stock rom, it has recognized the fingerprint on the screen and all the functions, and it recognizes me as the double sim version, it recognizes me the sim and the number of it, but it comes out imei 000000, my doubt is that they have blocked the network by software or hardware, a few months ago I saw a video of a s6 demo vs s6 normal and they have disconnected the network card
I have a s10e live unit demo and I have a imei 0000000 but the phone info apk find a modem and modem version inside the phone. Samsung inclued a bad imei in the version of galaxy!?
I have s10 ldu also i already wrote imei also. Sim card detects but signal strength very low. -113dbm 0asu. Showing network provider also

writing imei's to LDU's is borderline not allowed lol.. seeing as how they dont come with them you would need to obtain an imei from somewhere which in some places is even illegal.
also, i believe it does have some capability but after flashing my g975u to g975xu i was not able to enable mobile features.. flashing back to g975u mobile features worked again...
also, i noticed while on xu firmware the device is shown as a wifi only device.. this cannot be changed without some form of root im afraid so i dont think mobile services while on xu is possible..
on the other hand though, an ldu on U firmware should in theory work if you managed to somehow (wont discuss methods here) write the imei and other network related info...
to add, it wiped my efs.. but luckily that didnt kill my imei or anything as i believe it is stored elsewhere and is protected.. of course if anyone tries and has other issues then i am not responsible lol
