Please make sure of these:
1) LTE bands overlap between your device and the carrier.
2) The SIM card is not 3g only. Some SIM cards are LTE disabled.
3) Make sure your device is LTE authenticated through the carrier. Some carriers can limit your device to only connect to 3g to maximize the LTE for carrier-branded phones and users.
If above doesn't work, the Android 5.0.1 update is on the way with new firmware/kernels/drivers for LTE modem and radio functionalities, so I would hope for the best.
One morning when I woke up my N9005 was stuck in the boot animation. I waited a while but I had to hold the power button in to force a power off. Since then I have had no 4G at all. 4G was working before this. Can anyone suggest anything that might re-enable 4G?
Contact your operator.

It's nothing to do with my operator. I have tried two different SIMs from two different operators that both worked with 4G before. I own the phone, it came from eBay but as I said it was doing 4G before.

I'm not sure why "Available CSC Codes" is blank.
Could that be part of the problem?

I already did that. At least I think I did it right. Afterwards it started up exactly as usual. There was no extra optimising apps like after an upgrade. I used Odin. Do you think I did it right? I also tried a factory reset. Still no 4G.

I can't help anyhow but what I do if I loose LTE connection I force it back with 4G Switcher app. You choose LTE only and it should connect (though I can't call or receive calls in LTE only mode) so what I do is when LTE conects I swap mode to LTE/Gsm auto and LTE stays as long as I'm on LTE area (until I somehow loose LTE again in area where LTE is available). Try that out maybe it will drive you to some new conclusions what the issue may be.

Do you mean this one?
https://play.google.com/store/apps/details?id=com.tapbase.LTEswitcher
It says it's incompatible with my device!
Also it sounds like you had the situation where you lose the ability to select "LTE/WCDMA/GSM (auto connect)" and can only select "WCDMS/GSM (auto connect)". I have not lost the ability to select "LTE/WCDMA/GSM (auto connect)".

1- Yes, that's the one
2- It works on my Note 3
3- As to your assumption...well I'm not sure what you talk about. I'll explain my issue. Sometimes when I'm on LTE available area my phone connects to HDSPA+. Then I do what I described (I choose LTE on this app to force connect via LTE). I don't know do I loose "ability to select "LTE/WCDMA/GSM (auto connect)" as you said. To be specific what are you reffering with it to? To phone settings or to this app setiings? All I can choose on phone settings is 2g,3g and 4g. There's no X/Y auto connect. This option is in apps settings though and I don't really care what I loose there as long as it works when I want to force LTE with it. I'm courius why it's not compatible with your device. What phone do you have?
All in all in the end use of this app won't solve your issue permanently but with it you could make sure LTE receiver and LTE drivers on your phone system works. Then you could dig down further. You would just know that LTE works at all on your phone.

"LTE/WCDMA/GSM (auto connect)" is a setting on my phone. See my Screenshot_A.png above. It tells the phone to automatically switch between LTE (4G), WCDMA (3G) and GSM (2G). The other choices don't include 4G. I reach it by Settings / Connections / More networks / Mobile networks / Network mode.
Is you phone rooted? Mine isn't. Could that be why the app doesn't like my phone?
Further info: apparently the phone was originally Portuguese but has been flashed with UK BTU firmware. However as I said before it definitely did do 4G when I first got it. Samsung tried to tell me there was some kind of update that might has disabled 4G in the UK for this device. Sounds like a made up excuse to me.

I think so. Isn't the info in my screenshots of Samsung Phone Info Plus (in a post a further up the thread) enough to confirm?
If not could you guide me how I can check. Thanks.
I compared it to uk firmware on sammobile.com and it seems to match. Maybe you need to flash the entire uk firmware again in Odin?
Still same. I've taken it to a Samsung service centre now.

It's back, and it's working fine now. And, nice surprise, it was apparently just inside it's guarantee period so I didn't have to pay.
I'm not sure what they did but it's back on Portuguese firmware, which doesn't seem to matter, I just select English (UK) after factory reset and all is well.
Oddly the WiFi adapter has a new MAC address but the magnetic field sensor must be the original one since it's calibration is way off exactly as it was originally. (You have to calibrate it after every reboot by rotating the device in three axis if you want compass functions to work).

I have a SGS5 (SM-G900F) downgraded to Kitkat. (4.4.2)
I can use LTE with one operator A (4G shows in statusbar, speedtest measures above 50Mbits).
I bought a sim for operator B but I cannot switch to LTE mode in Mobile Data Settings -> Mobile Networks -> Network Mode. Any option with LTE is simply not available.
I tested the sim for operator B on an iPhone 6 plus, it works just fine.
I have found some guide for secret codes and walked through it to force LTE. It works, but it does not switch to 3G automatically when I receive a call (it does this with the card of operator A)
So I know that my phone does support both operators frequency bands, I can force it to work, but I want to have the convenience of automatic switching on a phone call.
Is there a list somewhere in the software that has flags for networks to enable and disable LTE options in the menu ? Can I edit this ? Where is it ?
Will updating my Android version fix this ? ( I would really prefer to avoid this, since I use SnoopSnitch )
Operator A is: Vodafone (DE), A1 (AT)
Operator B is: HoT (AT)->MVNO for T-Mobile (AT)
I have a new SM-G935FD purchased in the UAE. The software version is MMB29K.G935FXXU1APD1. The phone has a "United Arab Emirates" section in the About page.
I travel a lot. I generally use a local SIM when I am in a country for some time. Right now I am in France. I am using a SIM from Bouygues Telecom but I have no 4G/LTE service at all. The phone is connecting at H+ and also at 3G, but it is not showing 4G/LTE at all.
I will be in several other European countries as well as the US soon. I specifically purchased this phone because it has all the LTE bands for the countries I spend time in. This same SIM does give me LTE connections on Bouygues when I use it in my old phone (a Motorola X 2nd Gen). I had expected this phone to just work on LTE everywhere that I typically go.
I have looked through these forums and see a thread or two about others with LTE problems. But no clear solutions.
I have tried various apps such as LTE Discovery (no luck) as well as 4G LTE Switcher - using that if I set "LTE only", I get no service at all, and then have to reboot the phone before I get service back.
Is there something I need to do to get LTE?
Thanks.
Have you put the SIM in the correct slot?

Yes, the bottom slot. The SDcard is in the top slot. The SIM is showing in the phone as "SIM1".
Strange. I have a G935FD and it works with LTE no problems. I've used it in Singapore and Indonesia, with different SIMs and all work.
In Settings - Mobile Networks - Network Mode, it's set to LTE/3G/2G?

Yes it is. I've tried changing to one of the non-LTE modes and back, but no change.
In the About device / Status / SIM Card status page, I see Mobile network type as UTMS. Shouldn't that have LTE and, if so, how do I change it?
Mine says the same, but I'm only connected to 3G at the moment, so I don't know if it's normal it not. I have a 4G card in, but I'm out of my area's 4G network range.
Edit: Actually I was connected to my wifi. Now I'm connected to my 3G and it says HSPA+ now
Edit again: Ok, so my phone is jumping between 3G and H+, which is what's changing.

Ah, mine is doing the same. I see Mobile network type jumping between UMTS and HSPA+ if I watch for a while. Obviously that field is a status field, not a setting field.
Thing is, I am in an area with full LTE coverage.
At least you seem to be confirming that this should work. Still need to figure out what the problem is.
I have the same Problem in Spain. With a Vodafone Card I dont have 4G Connection (The same card in a the Galaxy S5 of my wife works with 4G). But with a Yoigo Card I have 4G Connection. The software version is MMB29K.G935FXXU1BPH6. The phone has a "United Arab Emirates" section in the About page too. Any Idea?
Thanks
READ THE [UPDATE] DOWN BELOW
Many Note3 Korean Variant users also reported this case
https://forum.xda-developers.com/showthread.php?t=2484602&page=115
The problem is that, I can't connect to LTE without losing my Network Radio Service Connection. I can connect to E/G/3G/H/H+ and still have network service, so I can still make calls and text messages, but when I turn on my Mobile Data, when it tries to connect to LTE, suddenly my service gets diconnected and I can't make phone calls nor messages though I could still use the data. I've already tried 3 LTE-Capable SIMS but the issue still happens.
What I had in mind is that it might be because it is Carrier Locked since it is a Korean Variant, but the problem still persists even after flasing other custom roms (this includes Note 7 Port ROMS, LineageOS, Stock-Based ROMS).
I love my Note 3, I will do anything to keep it alive, but still this one problem keeps bugging me...
Why can't I use both LTE data connection and radio service connection simultaneously?
Is anyone out there knowledge and willing enough to help us Note 3 KV users with this issue? :crying:
[UPDATE]
I get it now, when a phone is using LTE it means its not connected to any Mobile Network Service, instead it is connected to Data Network Service, yet it should receive Phone calls and Messages but it means that the phone will disconnect to LTE and switch to GSM/WCDMA (E/G/H/3G/H+) to be able to recieve the incoming call or message. I've tried that with my friends' phones, The first phone is connected to Data and is using LTE and the other phone is trying to call the first phone. The moment I call the first phone, I noticed that the LTE icon dropped to H and then recieve the call, It only happened because the option selected on the "Network Mode" (under Settings/More Networks/Mobile Networks-->Network Mode) is [LTE/WCDMA/GSM auto connect] so that's how it works
But that doesn't happen to my phone, after turning off the Mobile Data (I was connected to LTE btw) my phone doesn't automatically connect to GSM nor WCDMA network, it just stay on LTE mode and I have to manually select the GSM/WCDMA option in order to get Network Service.
So my final question is Why doesn't my Note 3 automatically switches Network Mode?
Note 3
Model Number: N900L
Status: Rooted with Custom Note 7 Port ROM
Condition: Good, No History of Repair
Current Network: SMART Prepaid
Does it work on genuine non custom stock firmware ??

Please start to read about LTE technology and its frenquency bands.
Then find answers to these questions :
1- My SM-N900L is locked to use which frequency bands ?
2- Wich bands are in use in my actual location (country) ?
3- Is it possible to unlock more frequency bands for my N900L ?
i can provide more help if things remains not clear enough.
Good luck :good:

I tried searching the supported LTE bands of N900L but I can't find any sites that tell exactly what the N900L actually supports though I found out on this forum
https://www.frequencycheck.com/models/AZzWA/samsung-sm-n900s-galaxy-note-3-lte-a
1) A / P / T / V models are made exclusively for the US operator market and for no other people, as their indexes hint (A-AT & T / P-SPRINT / T-MOBILE / V-VERIZON). In Europe, mainly international versions are used - in the case of NOTE 3 - exclusively N9005, in Canada - its own carrier versions.
2) The models N900S / N900K / N900L are identical in the set of supported frequencies. If you rewind the topic on page 9, you will see screenshots of one of these models, which show the frequencies you are using, in one of the screens you will see the treasured frequency of LTE b7. I think that users of this topic can be trusted with respect to information in the topic, but no one has elected you the right to believe solely on the site www.frequencycheck.com.

I did try checking my phone on www.frequencycheck.com, N900L is not on the list..
https://www.frequencycheck.com/models/AZzWA/samsung-sm-n900s-galaxy-note-3-lte-a
N900S though shows that it supports Bands 3, 5, and 17.
I also look it up on wikipedia on where the SMART network (my current network) falls on the list of LTE frequency bands, and it shows that it is on Band 05 alongside with South Korean Networks LGU+ and SKT. The supported LTE bands on my country are Band 1, 3, 5, 7, 28 and 41
https://www.frequencycheck.com/countries/philippines
I searched for how to unlock all LTE frequency bands on N900L or Korean Variants or Note 3 but the only option that shows up is by accessing the Service Menu on Stock ROM and manually changing the values, which still didn't work for me.
According to my search, N900L is locked to :
LTE protocol : B1 (2100) and B5 (850)
LTE-A protocol : B3 (1800) and B7 (2600)
Now try to find the specific frequency band used by your carrier (he can't use all of the six available bands in Philippines), and activate it.
Wich stock firmware do you use when trying to access Service Mode ? It must be the LGU+ one.
And what code did you dial for the same purpose ?

When you said activate, you mean select the band to be used by the phone right?
- Yes, I used the LGU+ Lollipop Stock ROM
- I typed in the dialpad, *#0011# and changed the network preference to LTE ONLY.
