Dear all,
You are my last resort. I've been trying to find out how to fix the problem, but no success...
My Note3, 9005 (bought new, without contract), has never been rooted or modified in any way. Current version is 4.4.2. IMEI is fine. Well, I am a regular user, who keeps updating the phone, when there's an update from samsung OTA.
I've been using the phone for 1.5 year, everything was fine. I recently switched the operators (Belgium) maintaining the same phone number. And there the problems started.
Very often I get "no service" message, although data connection works fine. I tried automatic and manual selection of the network, but the problem remains. When I select automatic network, I get the message "registerred on network", but "no service" sign remains and get no call connection (data connection works fine). When I select the network manually, I get a brief message "registerred on network", but still no service and then "the network is unavailable"/
I contacted the operator, they claim that my account is fine, they see no problems on their systems. The interesting thing is, that other operators SIMs work fine with my Note. Apparently, it is only my current SIM which fails to work. I have two different phone numbers SIMs from this operator and they both have a frequent "no service" in my Note. I have also requested a new SIM, which again did not work... The same SIM works fine in Sony Xperia. I have also tried that same SIM in galaxy s3 (LTE). And there was again a problem with connection, i.e. no service, but data functions fine. I have also tried different modes (3G, 4G), the problems remain. It looks like it is the problem with samsung devices.
This is the time when I really need the phone for my work...I keep failing my clients because they cannot get hold of me. And changing the phone number and operator would be very inconvenient at this time.
Is there anything I could do to fix it?

try to flash stock firmware of your country via odin. i hope its work.
Nico, many thanks!
I understand my phone was brought from the UK. But currently I am in Belgium. Could you please tell me, what country firmware should I use, what specific firmware I have to flash? (I would appreciate if someone could refer me to a download link...I am not very good with these types of things, I am afraid to mess things even further...)
rooted, reinstalled stock 4.4.2. Now when making a call, the network dissapears and connection dissapears and becomes "no service", therefore the problem remains. data connection works fine.
guys, please advice, what can i do to fix it? should i go for other ROMs (not stock), would that help?
i've read about ariza patch, but did not understand whether it is available for note 3 4.4.2.

1. Install Kies 3 and conect your phone to the pc.
2. Take a look your CSC (pic attached)
3. Go to Sammobile.com and download the correct firmware (with correct CSC) for your device.
4. Flash this firmware through ODIN.
5. Enjoy :highfive:
* Dial *#1234# when you finish all process and add it here for avoid problems

Joku, thank you very much for your reply!
But I think I did exactly what you have recommended in the first attempt - flashed the stock version. Please see the pics of kies and suggested sammobile firmware attached. ...But "no service" problem remains. Althoug, I must say, it goes away from time to time (better than it was without reinstall). Maybe I should go for other country firmware (for example Belgium, where I am currently based and where the problems persist)???
After reinstall my firmware is:

All seems ok. Make a thing:
1. Backup your data and factory reset your phone (Pic attached)
2. Tell me if you have service then.
This is obviously a carrier issue as you stated yourself other carriers work fine. You can waste your time throwing things at the problem, but I'm highly confident it's not going to be fixed by anything you do.

It does sound like a provider problem...
Try a factory reset first, just to be sure. Best do it through recovery, so you can wipe the cache as well.
Does the no service happen everywhere? Or just in specific places?

Thank you all for your replies.
The problem is that the same 'no service' SIM works fine in another phone (sony xperia), the provider will claim that it is note3 fault.
I did factory reset after I reinstalled the stock version.
It looks like ' no service' appears when the phone changes the cell/network towers when travelling from one location to another. .. But I can't say that it is always the case. I just don't find any logical reason to fully explain that.
The weirdest thing is that data connection works fine always.

It is probably related to the way your provider does the 2G/3G/4G band allocation and switching - what provider is that?
You can also try to set the data to "3G only" vs "LTE/3G/auto" and see if is any difference.
The provider is Base (via virtual network provider).
I've tried everything, including changing to 4g, 3g, etc. Nothing helped : (
Should I try flashing different modems? The question is, which versions should I go for. ..?
updated to lollipop. no changes
I still haven't solved this issue. I just updated to lollipop (via CrashRom), the problem with "no service" remains.
Is there anyone with similar problems, who was able to find an answer? What else could I try? Should I try flashing different modems? Could anyone help me choosing which modems should I try?
pleeeease.... : )
anyone please?
can I try flashing different (older) modems? would that mess up my curent rom?

Check this post for downgrading from Lollipop to KitKat.
Regarding to "No service" problem, go to the ServiceMode MAIN MENU and try NV REBUILD.
To open the ServiceMode MAIN MENU:
- If you have root, install Phone INFO ★Samsung★ app > Menu > 'Secret Codes' > *#27663368378# > 'Launch 0'.
- If you don't have root, open the dialer > *#0011# > Menu - Back > Menu - Key Input > Q0 > wait... until it appears
iritoi said:
firstly, many thanks for your advice to rebuild nv.
i did as you explained, but... it did not help.
i went through all of the options available, flashed stock firmware, flashed various roms. nothing helps. what's interesting that i have call availability (service) for some time, but when i move to different area, the service dissapears and i have to turn on/off airplane mode. and this happens with specifically one provider (mobile vikings/base - belgium). if i insert the other provider sim, note 3 works fine.
my imei is ok.
pleeease help me to fix this problem. what else can i do? is theo nly option left to change provider?

From your first post, I have no idea about your problem.

(1) + (4) ==> your Note should be OK.
(2) + (3) ==> the SIM is OK.
Currently I have no idea.
Your best bet is flashing back to original stock firmware.
And try to check your SIM card in your Note 3 by follow these steps:
In the ServiceMode MAIN MENU, select DEBUG SCREEN > SIM INFORMATION, you will see 3 options. Select every option, capture screenshots and post it here more more checking.

In the band frequency it says "unexpected value". Maybe that has something to do with the problem... Or am I being listened by secret services : )

Mine are the same.
Except for the 1st screen: SIM Phase = 2; SIM voltage class = 3V.
The 2nd and 3rd screens are the sme.
is there a way to see the reason why the network is being disconnected via service menu?
...because when i turn airplane on/off, the network comes back. but when i dial the number it disappears right away with the message "network not available".

Yes there is. Here is how:
- If you have root, install Phone INFO ★Samsung★ app > Menu > 'Secret Codes' > *#197328640# > 'Launch 0' > BASIC INFORMATION (capture screenshot #1) > Menu - Back > NAS INFORMATION > MM INFORMATION (capture screenshot #2) > Menu - Back > MM REJECT CAUSE (capture screenshot #3).
- If you don't have root, open the dialer > *#0011# (capture screenshot #1) > Menu - Back > Menu - Key Input > Q0 > wait... > DEBUG SCREEN > NAS INFORMATION > MM INFORMATION (capture screenshot #2) > Menu - Back > MM REJECT CAUSE (capture screenshot #3).
And post these 3 screenshots for more investigation.

So I followed all the guides. Expect here where I stoped on each.
Z3X method, I DO not own Z3X nor a Box, so however I have ever other step complete, I just need something for step 8 to "Unlock" and was able to skip the rest of the steps via other methods.
The S4 Thread, the service menu is different and I can not find the Sha256 option to Edit but I find the value telling me its on.
However I found a APN list setting value and changed that, waiting on sim Card | will update, SO this is an Verizon to Boost mobile attempt.
So thought and/or advice? The phone has TWRP via Safestrap. or can easily.
There is also A list of bands COULD(can't edit or not sure how) be enable and disable for LTE like band 28 and others CMDA that sprint and verizon share.
The APN List setting must be the Unlock for this phone as I plugged in a US cell and DID NOT put in APN.
3G data Worked off the Bat and got phone signal but did not receive calls, thinking due to no APN.,
Going into Boost tomorrow and Asking to borrow a sim and See if they will get me a Valid APN or grab the one off APNsettings.net.

Hi All - hoping to get your help and advice.
Original S8 was a USA SM-G950U on T-Mobile that was successfully flashed and unlocked to SM-G950U1 (CSC = XAA). The phone was fully functional, successfully received OTA updates and was on the latest firmware (G950U1UES5CRL2) in use in Hong Kong (3HK 4G LTE) until yesterday when I did a hard-reboot and cache-wipe a few days after a system update and now the cellular radio won't connect to any network. I've tested the SIM card (works fine on other phones), rebooted without the SIM inside (no impact), tried upgrading to Android 9.0 as well as older Bootloader v5 firmware to see if the cellular radio would turn on and re-connect but no luck.
Current State: When looking under "Mobile networks", Network mode shows "Preferred network mode: CDMA/EVDO/GSM/WCDMA" whereas it used to be "LTE/3G/2G". This option is available under the drop down list but I can't selected it. Under "Network Operators", tapping "Search networks" results in an error "Error while searching for networks". Tapping "Select automatically" pops an error "Unable to connect. Try later".
After exhaustive testing, it feels like the phone is behaving like it's SIM-locked since everything else works thru wifi but it's on the SM-G950U1 XAA unlocked firmware so it shouldn't be locked?? Any suggestions would be greatly appreciated.

Thanks for your feedback! What's strange was that my S8 with the unlocked firmware (SM-G950U1) was working perfectly for 6 months and I was able to make calls, get LTE data connectivity, etc. Now the phone is still working via wifi but the cellular function is dead. Any suggestions or advice on how to remove the T-Mobile SIM lock?

We need to verify some how if it truly is Sim locked or not first.

I've tried 2 different SIM cards (though both from the same carrier) and both were not connecting to the mobile network. The phone can detect when there isn't a SIM card inserted so that is a minor indicator that the SIM card slot is functional.... any other suggestions on how to verify whether my S8 is SIM locked?
EDIT: Both SIM cards work in other phones (iPhone6s, iPhoneX).

Of coarse not always but most of the time it will display a warning or something about sim not accepted. This sounds like to me. A couple things. Simlocked. Maybe install the T-Mobile firmware again and try the T-Mobile unlock app. It should say this device is already unlocked or successful. If that passes. It could be a disabled band or something. Sounds like the latter. Like it's not picking up your carriers signal. Again the us models I believe are pretty universal so maybe a different firmware may enable it again. Or last the device has somehow become blacklisted which unfortunately I have seen plenty of people here in US sell devices still on contract maybe pay a few months and quit then blacklists

You can't fish 950f different chipsets. What country are you trying to use it in. If it's blacklisted that's more than likely your answer right there.

Yeah can't flash 950F, Russia - No T-Mobile here. Don't know what to try right now, possible try get stock TMB, then unlock network again if its lock. No blacklists, T-Mobile support says status Clear, but maybee contract on T-Mobile not paid. Trying to flash custom modem, but didn't help too.
