If it was working before, I dont think it is hardware related. Download and flash a new modem. Or download your stock rom with your contry specified modem. while flashing custom rom, dont update modem.
That shall do it

happened to me as well after a nandroid restore.
Just reflash the modem. I also had a EFS backup and restored that also. Worked like a charm.
If that doesn't work, then ODIN a stock ROM - it should definitely do the trick. Be mindful though that it will erase your internal SD card unless you go for the modded ones.

i did every thing not working .. i took it to the service centre they say the radio is broken .. and corrupted coz of flashing the rom and now i hav given it to samsung to change the motherboard

Hmmm - tough one.
I guess this could only happen by flashing a wrong modem software...
Hope you get it fixed soon

[Q] Insert Sim to Access Network Service.. IMEI Null

Hey Guys,
I have an AT&T Model SGH-1317 Note 2. For use on other networks, I unlocked the phone using the *#197328640# menu option. However, the phone failed to start the hot spot stating Mobile data was unavailable or Invalid Sim. However, I am able to tether perfectly using the same sim on an another S3 so I was sure its nothing to do with the sim or network operator settings.
I looked up and found XDA website with tons of information. I assumed my phone was locked by AT&T. Hence, I rooted the phone using CF-Auto-Root, backed up complete data using Titanium and using Rom Manager I installed the Crash Aroma 4.1.2 Rom. I wiped the data and cache 3 times as suggested. However, after the boot I am unable to connect to any mobile network. A Click on Mobile Network says "Insert Sim Card to Access Network Services". Dialling for IMEI number prompt a Null.
During Installation I noticed the Crash ROM has overwritten the Radio.. and I am assuming this is were the problem lies. but I leave it you experts.. Request Help!
Sunil.

What carrier are you using the device on?

Am currently on Du - A network in Dubai, UAE. I have been reading more forum information and some suggest that this may be related to the EFS folder getting corrupted which may cause the IMEI number to fail. Some suggest that there are software to rebuild this information by using the IMEI number behind the handset..
I also noted that my phone model has also changed to GT-7100 instead of SGH-1317, Wonder if the Crash ROM was apt?
Would you suggest installing a Jedi Rom specifically built for SGH-1317... or is the damage already done?

Back Online
Since I found no replies.. I had no choice but to give it to the Pros.. I handed my phone day to one of the Unlocking experts at a mobile store… He was confident that his technicians would resolve this. But after 2 Days, they have given up.. He suggested the phone would fetch me US$ 10 if someone used it as a demo unit at a mobile shop..
I was sure this was something to do with the Modem, IMEI and the all important NV folder. I was able to find a Stock ROM for the SGH-1317 and I also found a link at XDA about using EFS pro to change the IMEI.
Using Odin software, I flashed the phone with the stock rom. Unfortunately, there was one error when it tried to communicated on com1. Having no choice, I continued. Restarting got the AT&T style boot but it again froze on the Samsung screen. Dreading the communication error, I restarted several times with no results. Finally I realised if would be due to the cache and user data. I reset the phone to factor settings wiping out the user data and Whola.. The phone sprang back up..
Lessons learnt.. Backup your rom and data before playing with custom roms. Read Read Read and don’t flash in the middle of the night..
Since I am back online, I plan to stick to the stock and crappy 4.1.1 with all the AT&T dead weight. Will live without the ability to Tether until my fingers get warmer.. It won’t be long as I am already bit by the Custom Rom Devil..
Don't Give Up Easy..:good::victory:

Please I am having the very exact same issue and can't seem to have it fixed
Using CMW I also flashed it back to stock rom, didnt have any problem or errors doing it but im still getting No SIM Inserted. I have deleted cache and user data several times... Tried flashing CM10 and CrashRom see if they made a difference and still No Sim Inserted... tried 3 different kernels and still same issue

I have the exact same problem since yesterday. I've tried everything and anything to no avail. I'm very close to returning the phone.
I would really appreciate any input.

Same issue
I flashed crash rom 4.5, over the stock kernel and it gave me that same message. I've tried everything I could think of, which included everything in this thread to no avail... any further advice would be greatly appreciated.

Your username suggests that you have the N7100 device ??
If so. ..you are in the wrong place for support. ..As this is the SGH-I317 section.
If you are showing IMEI NULL with no baseband you may have to restore your backup image to correct the problem. .
If no backup image exists. ..you will need to flash a factory N7100 image from your section.
Look for the return to stock thread for your specific device and that should fix you up...
The CF AUTO ROOT files are device specific. ..so I hope you haven't damaged the partitions.
Good luck. ..g
Edit:
This will help. ..and will place you in the right section. ..
Just go to page 1...good

And finally you have paranoidandroid or back again in the previous rom? With a little search in the forum i found this "Hey...I found out why I didn't have service and was able to fix it. When I had flashed AOKP, there is a setting in the Mobile Networks screen to change the CDMA subscription to RUIM/SIM. Somehow (probably playing around) I changed it from the NV to RUIM/SIM. THEN, I nandroided back to stock, and had no service. As far as I know, that CDMA Subscription option isn't on the STOCK ROM...so I was baffled. Good thing I remembered what I did."
Try it and report..!

i'd recommend that you flashed again your previous rom to see if it is rom related or not. I ve read somewhere that some people had problems with the signal when flashing aokp.

i going to take it to the samsung cc....... lets see what they will say about this problem

I am suffering a very similar and strange problem. I have a Dmc3 deodexed and rooted Rom with NEDLK1 baseband (3 ITA operator) since 3 months. I have done nothing special (no new apps nor flashes) in the latest weeeks. I have never flashed any other ROM. But 2 days ago I saw NO service. I have correct imei, could even surf the web but no telephone functions. Rebooting the phone did not work.
I thought of a SIM card issue and yesterday I asked my operator for a new sim. While I was waiting the new sim to be enabled, today I pushed in my Note 2 another SIM by another operator. After some hours I had the same trouble with this SIM.
So the problem is the Telephon. I don't know if hw or sw, but there is an issue.
Now to see what may be, first I changed the baseband Modem and flashed a stock XXDLK7 and inserted the new Sim inside. Now I will wait and see.
In case of continuing issue, I will try and go back to full stock operations.

Hello guys. I had the same problem, and it was a hardware problem. The solution is really simple: put onto the left of the camera, inside the chassis, a small piece of papero of 3 mm. It's enough to strenght the connections of the flat of the SIM card connectors to the motherboard

Mobile data not working +STOCK ROM

Hi everyone,
I have LG G3 d855 (Europe version). I bought it online, not at any network. I had an lollipop update really fast (Poland). Yesterday I rooted the phone, it worked fine, and installed the BlissPop rom. I missed the Quick Circle option though, so today I installed the ChupaChups rom for lollipop. And now my problem: The mobile data connection is not working. I can make calls, send texts, connect via wifi, but the data connection over the network is not working at all. I went back to stock - I downloaded and installed the European version using kdz method, it didn't help, so I did it over LG Flash Tool. It still does not work. Do you have any ideas, what to do with this? I feel like I'm going to cry, I'm very nervous about it, because I use mobile data almost all the time...
Maybe there's something wrong with the modem driver? I really hope someone is able to help me. Thank you in advance!
Edit: Maybe I used the wrong stock rom? I don't even have the option to update to lollipop anymore.

Seems like a modem baseband was flashed somehow.
Flash the modem back to the correct stock version you had and it should fix the problem

Do you know where I can find those modem drivers?
Edit: I checked which version of software I should use with my IMEI no. It's 20h. Would it be enough to flash the stock rom over kdz, or do I have to find somewhere the modem driver for this version? If yes, do you have any idea where can I find it?
Thanks.

Not sure.
I have the G2 and we have these files in our Development Section where you find ROM files etc.
Should be there as flashable zip files in the same section for the G3

Ok, thanks! Last question before I do the final step - I have the ROM I am supposed to have. I rooted the phone, installed TWRP. I've also found the modem driver for my rom. And the question is - how should I flash the driver? Should I mount system or do anything apart from just installing the zip? Should I clear any cache?

@CaPlanePourMoi Wipe the modem partition in Recovery and then just flash the modem zip which will replace it. If that doesn't work, you can go back to BlissPop that includes it's own Modem and install Xposed for 5.1 Super-Alpha and the QuickCircle Mod for AOSP, all 3 of those I'm using with no issues whatsoever!

So I installed the modem driver (20h) yesterday, but it didn't help. I decided to install the BlissPop ROM, and mobile data (with LTE) works just fine. I will go back to the problem on Saturday and keep you up to date. Thanks!

Update
Update: Hey everyone - it seems like I didn't find any solution. I tried to go back to the ROM based on stock again (it was Cloudy this time), but the modem still didn't work. It was acutally working for a few seconds (I had 4G connection), but then again it was lost and it didn't connect anymore. Wifi works fine. Do you have any ideas on how I can flash the modem correctly? And how can I uninstall the modem that I have now in recovery? I didn't do that, because I cannot find this option.
Thanks in advance!

I have a very similar issue
my LG G3 is the D855 on AT&T , and was working fine on Cloudy 2.2 or 2.3 Lolipop without any issues!
All of a sudden last Friday 5/22/2015, mobile data stopped working, but WiFi is still okay.
I just did a full wipe, updated APN, and the issue still there
I haven't change any major things in probably 2 months, not sure what's going on.
Finally, contacted AT&T, and made sure that they remove from the network,a put my back(troubleshooting). As well as changing the sim, and APN, but nothing worked!!
PLEASE HELP!!!!!!!!!!!!
UPDATE: So my last attempt, I contacted my provider AT&T, and they requested to try a default APN settings, even though what I used was working fine.
I did, and immediately my mobile data was back!!
Everything is working back as normal, and for some reason the network APN required updating

Did almost the same few days ago! I have finally solved my problem. Here's the explanation:
In Poland we had a network called "Era", a few years ago it was bought by T-Mobile. I searched the internet for T-Mobile APN settings in Poland and it didn't work. I have also found the APN settings for the old network, "Era" and surprisingly it's working. I don't know why T-Mobile settings don't work while they do for other people (and at this point I'm too afraid to ask. )

HI, i have the same problem on my d855 with wind (i'm in italy), i was rooted with custom rom and when i came back to stock i lose data connection. What i have to do? what do u mean for restore default apn? the default of my carrier? or the default for g3?

no H+, H, E or anything showing when data is on

Data works fine, there's internet connection available but there's just no icon showing the status of my data connection, is there a fix for this ? I have the h815 on V10e-eur

Is your phone rooted?
Did you install a firewall like avast?
I use the avast firewall in whitelist mode and had the same problem.
I had to allow a group of apps at the end of the apps list to make it work again.

yes it's rooted and no there's no firewall

ok.
so I guess it worked some time ago, but then stopped working suddenly?
You can try a system reset, but you will loose your data and settings, so backup everything.
An other mehtod could be to flash a kdz to unroot your phone and try if it works again.
Or did you install an adblocker? I am using adaway, but have no problems with the icon.

I did all the things you mentioned, it didn't work since I bought the phone 4 days ago, I rooted and installed twrp, then flashed another kdz with latest version and still the same problem, no adblocker nothing, it didn't work with a fresh updated kdz

If you say that it didn't work right after you bought it, I would not have rooted the phone, but give it back and get another one.
Can you try a different SIM card from a different provider?

Ok, good.
So you know your phone is not the problem.
But it's strange that your SIM card seems to be the problem...
Maybe you should ask your provider about this problem or try your SIM in a different phone.
