If you dial *#*#4636#*#* do you get the testing menu? If so, go into Phone Information and check you are set to LTE/GSM auto or similar.

If you input that code in the dialer (correctly) it should take you to a screen called "Testing". If it doesn't then there is something wrong with your phone. This works on pretty much all phones.
@GDReaper: The Galaxy S4 does not recognize that particular version of the USSD code. It can be run however through the Phone Info app.
@khsh97: Please post the following information:
1. Model Number
2. Android Version, found by going to Settings > More > About device.
3. Firmware Version (AP, CP, CSC), found by dialing *#1234# in the dialer or by installing Phone Info from the Play Store and running it.
4. Service Provider
5. Country
6. Is the phone rooted? (Yes/No)
7. Is a custom ROM installed? (Yes/No, and the name of the ROM)
Before using GDReaper's suggested method, post the information requested, so that we can eliminate other possibilities for why you don't have a LTE option.

I ran the code before posting and it worked on my S4. However, am running the gpe rom. Maybe that's why it actually worked
That is probable, as I'm running a rooted and debloated Touchwiz and it didn't work. But as mentioned, the Phone Info app is another way to get there.
Sorry for late reply!
Model No: GT-I9505
Android version: 4.4.2
Firmware: I9505XXUGNE8(official stock)
AP: I9505XXUGNE8
CP: I9505VFGGNE8
CSC: I9505VFGGNE2
My phone is rooted with towelroot however the option was missing before root as well.
BTW, I don't have LTE sim, does that matter?
If that matter then how can I check without LTE sim?
And yeah, the code *#*#4636#*#* is not working in my galaxy s4.
I am going to check out phone info app.
If you don't have a LTE SIM, you won't have LTE as an option. Upgrade your SIM to a LTE version and you should then be able to select LTE.

Ok, thank you...!!!
By the way, why the code is not working on official touchwiz roms?
Ask Samsung that question, but don't expect an answer. There could be a multitude of reasons why Samsung disabled it, but unless they pony up a response we'll never know.
Lol, Nice answer!!! Anyway phone info app can do it so why we should argue with samsung for disabling that code.
I think you must have firmware based on your country to have LTE. Now I'm downloading 4.4.2 for my country and I'll keep you posted
@velizarcho123: And you'd be wrong. LTE depends on two things: having a LTE-compatible SIM and having the proper frequencies in the radio chip to pick up LTE service. Assuming the device is neither region nor SIM locked, the moment you put in a LTE SIM Android will load the APN for the carrier into Settings. LTE should then work immediately. If it doesn't, the APN can be modified in most devices so it does work.
That said, if possible, using the firmware from your home region is the smartest idea, as Samsung does modify the firmware a bit, usually by removing languages other than those spoken in the region.

All firmwares have LTE, I does a trick - rooted my phone and modified a system file that enables LTE in the network menu. This is stupid Samsung restriction.

Reread my post. You were able to modify the firmware, but that modification would not have worked if the SIM wasn't capable of LTE and the radio chip didn't support the frequencies used.
EDIT: Just to clarify, Samsung modifying firmware to remove the option to use LTE does not mean the firmware doesn't support LTE. Clearly it has to support LTE if your modification worked. This means that firmware is eliminated as a variable, leaving the two remaining variables as the SIM and the radio chip.

Hi,
I couldn't find anything related to this on the forum so here it goes.
I know that google has disabled LTE support in latest baseband release. And one would be able to flash the old baseband to regain LTE support. However there's many steps that one need to do to get it enabled (type in service code, change LTE setting, enter APN etc.), not to mention you also loose some enhancements/bugfixes.
So my question is that, is there any way one can build a custom ROM + modified latest baseband (4.2.2) to have default enabled LTE support directly? (means no service code change, APN change etc. and with all the possible enhancement from the baseband build)
If yes, please direct me to the post or instruction, if not, why not?
Thanks for answering!

You can just use the old baseband and have LTE on any ROM.

Thanks for your reply. Yes, as I stated in my OP, I'm well aware of the ability to use old baseband on the other ROMs to have LTE. However, I'd like to have LTE on latest baseband, and also native LTE support without fiddling with the settings.
I would like to learn how to do it if there's no one already doing it, just need some direction to the right documentation/guides or explain why its not feasible.

I don't believe the baseband software is open source. Since the LTE functionality was removed from the baseband itself, flashing a ROM is not going to restore it to the .44 baseband.

I see, that's what I'm afraid of, so I guess the best one can do is pack a .39 baseband with custom 4.2.2 ROM with default LTE configuration then? So I guess my follow up questions is how much of the LTE operation is controlled by the basedband module?
Can a ROM have LTE as Preferred Network setting?
I think its possible to have default APN configured baked into the ROM?

T-Mobile only has LTE in specific areas. Even though it is selected in the network mode, if your area is not LTE ready then it will revert to the best possible speed for your area. I am with Telus and have LTE enabled on my device but it shows 4G in my home as I'm in a fringe area. When I leave my home and travel about 100 meters, I have LTE and it will display the icon.
It was my understanding that T-Mobile disabled the LTE band on their device. If you rooted, it's possible you enabled the LTE band partially in that it's shown but even though selected, the regional settings have not been updated to reflect the ROM you installed for LTE capability.
Have you rooted your device?

OK, if your device is rooted, have you installed the T-Mobile ROM onto the device? Have you confirmed this ROM installs an LTE capable modem? If so, follow step 6 at the bottom of my thread to ensure you've enabled the regional carrier settings thus essentially turning on the LTE modem: http://forum.xda-developers.com/showthread.php?t=2489766.
If you do not have a ROM installed with an LTE capable modem, flash a compatible ROM and follow step 6 and you should have LTE capability.
Hope this helps!

Like mentioned, T-Mobile just recently rolled out LTE in specific areas. The problem here is not the network but the phones capability of communicating with the network. My device is from WIND Mobile (Canada). This company only supports 4G data. The phone is LTE capable but the modem has been crippled. I rooted my phone and installed the Telus ROM (which inadvertently installs the LTE modem). Once installed, LTE is no longer crippled and once I entered the correct APN settings for LTE, I had access under my network options to select: LTE/WCDMA/GSM (auto connect). Problem was when doing this, I would still only get 3G. The phone was displaying the capability but it had to be enabled by modifying the regional settings and selecting the provider ROM. At this point, everything was functional and LTE capable.
Hope this helps!

Like I've suggested to others, please follow the documentation from start to finish in the following link: http://forum.xda-developers.com/show....php?t=2489766. With regards to ROOTING in the first set of instructions, replace the downloadable file with that which corresponds to your model. With the second set of instructions, when downloading TWRP, from the linked site, go back one directory and download the hltetmo version of TWRP. When you get to the third stage of instructions, download the file which represents T-Mobile's version of the ROM.
This should work for you but if not, let me know and I can assist where possible. Another individual had a similar issue who was PM'ing me and with a bit of time and troubleshooting, they're now up and running.
Hope this helps!

Well, in my 3rd step, I've listed ROMS for the SM-N900W8 model and you required ROMS for the International 9005 model. I would first load into TWRP by powering off your device and then once powered off, power on again using: Volume Up + Home Button + Power Button (all at once). When you see the Note 3 logo, let go and you will be in TWRP. Ensure you do a full wipe/format through TWRP and now you will be ready to install another fresh ROM rather than overwriting an existing ROM which can cause problems within itself. Once at this state, download an appropriate ROM from this link:
http://www.samsungis.com/Firmwares/SM-N9005-Galaxy-Note3-Snapdragon.html
The ROM I would go with is:
Galaxy Note 3 (Snapdragon) SM-N9005 TPLPoland (t-mobile) N9005XXUBMI7 4.3 11.09.2013 1628120 Download
This one I think has LTE but if not, you're safe with downloading any one of these variants. If the above does not enable LTE, you must research the carrier to ensure they have LTE. Please ensure you follow the last steps of the instructions to enter into the regional carrier settings and select the 3 digit code for the carrier ROM you installed.
Hope this helps!
---------- Post added at 11:17 AM ---------- Previous post was at 10:58 AM ----------
FYI....
Here is a list of carriers world-wide who support LTE and the frequency they support:
http://en.wikipedia.org/wiki/List_of_LTE_networks
If the ROM I suggested does not support LTE, this is what I would recommend:
Look at the different carriers provided in the original link I gave you for 9005 ROMS. Match one of these to this link showing supported LTE carriers. Make sure the frequency of this LTE carrier is supported by your phone then download the ROM. Once the ROM is installed, go to your regional carrier settings as I've listed in my rooting instructions and change the 3 letter code to match the ROM you just installed. Once the device resets and reboots, you should have the capabilities your device originally crippled.
Hope this helps!

This is what I have gathered from you Baseband...
The model of device you have is a Samsung Galaxy Note 3 (International - Snapdragon). It was manufactured October 2013 and was the second batch or build released for public purchase. The Countries/regions your phone recognizes are as follows:
Austria
Belgium
France
Germany
Hungary
Italy
Nordic
Spain
United Kingdom
This means that you must install an International ROM supported by one of these Countries for the device to successfully load it and boot up. You currently have the device unlocked and are using T-Mobile. This does not mean you must have the T-Mobile ROM loaded on the device to enable features which have been crippled. All you must do is research 3 letter CSC code for the ROM you download and ensure that carrier supports the features which are currently being crippled at the moment with T-Mobile. Once the ROM has been downloaded and installed through ODIN, as previously stated, enter the CSC menu on your device and select the 3 letter code which represents the ROM you just downloaded. The link to obtain a ROM (as previously provided) is:
http://www.samsungis.com/Firmwares/SM-N9005-Galaxy-Note3-Snapdragon.html
Please make sure the ROM you download supports all the features you wish to enable and that it also supports one of the locations listed above. At this point, a ROM should successfully load and you should be operational.
Hope this helps!

The better question is you have an international model so what is your goal? Are you trying to install a specific ROM to enable features (like modem frequencies) which have been disabled? You cannot install another model ROM on your device or you will just go into a boot loop or soft-brick your device and you will need to go through a recovery process. I'm going to assume you want to install a ROM for a specific feature or set of features which can be done but you simply need to ROOT and find a compatible ROM with the features you require.

Its possible its the software.. But why would an LTE capable device not support LTE with its software lol.
If your sim card is LTE compatible then it'll automatically show up. If not a minor software update will fix it.

What effective CSC do you have? What SIM do you have inside the phone? 4G modes (and a lot of other radio-related stuff) are activated at ROM-level by some of the settings in your current CSC and how that "pairs" with the SIM that you have inside. Only later you need to have your SIM marked as LTE-activated by your provider (but of course without that it will never work).

a program like this (do not attempt to change it yet!)
https://play.google.com/store/apps/details?id=com.manniakk.cscselector
or better this more recent and more detailed one:
https://play.google.com/store/apps/details?id=org.vndnguyen.phoneinfo
I've searched the forums and no one seems to have an exact FIX for my issue. So I have a Galaxy Note 3 N9005 32GB black version, the phone works well in 3G, never had an issue with it but now my network provider recently upgraded their plan and offers 4G internet but my phone doesn't want to connect. The provider offers 4G through BAND 1 2100MHz and Note 3 N9005 does have that band but it doesn't want to connect. It only works on 3G and when I enable Mobile Data it says H+! Not once has it connected to 4G!
I wanna mention that my friend has the exact same N9005 phone and his phone works on 4G all the time. Both of us have the same contract with the same network provider!
The only difference between our phones is the CSC region, we have different CSC. MY SIM card works in 4G on his Note 3 and his sim card doesn't work on 4G on my phone. (we exchanged the SIM cards for testing). So the problem is from my phone not from the SIM card. My phone is also original, its not a Chinese clone! Its confirmed with "Samsung Phone Info" app from Play Store.
Here's a few things I already did that some of you may be inclined to recommend to me:
1 - My APN is correctly set
2 - I am on official stock Android Lollipop 5.0 latest version and the phone is not rooted
3 - I already did a factory reset + wipe cache partition
4 - I saw others suggesting that people may not be in the range of a 4G tower! Not the case! Like I said, I switched the SIM cards with my friend on a public bench, out in the open, not even behind walls. Of course and his phone connects to 4G with his SIM card and also with MY SIM card while my phone doesn't connect to 4G with neither of these SIM cards.
5 - In Mobile Networks > Network Mode, my phone is of course already set on 4G/3G/2G (auto connect) and by the way, my friend's Note 3 says LTE/WCDMA/GSM (auto connect) instead of 4G/3G/2G with the same language set on both phones. Why?? I know its the same thing and I know 4G stands for LTE and 3G for WCDMA but why does it appear differently on these phones?
6 - I already went to Service Mode via *#0011# and manually selected BAND 1 LTE, it says "no service" or "emergency calls only" if I do that so I switched back to "Automatic"
So what the heck is going on? This phone is giving me headaches! I'm close to smashing my phone! After this I sweared to my self this is the last Samsung phone I ever buy. Probably I will be switching to Asus or Lenovo in the future. Or any other phone that does NOT have this CSC BS! This CSC thing is a complete rip-off!
Im thinking that the problem could be my CSC perhaps?? My friend's Note 3 N9005 has a COA CSC (Cosmote Romania) and I have a XEF CSC (Unbranded France). Both phones are factory unlocked and work in all networks. They are not branded by any phone maker! His COA CSC is unbranded. Yes it belongs to a phone retailer but that retailer doesn't brand their phones, no bloatware, no SIM lock. If you buy a phone from Cosmote (with COA CSC) it works in all networks, unlike Vodafone or Orange who lock their phones and brand them.
What should I do? Should I attempt to change my CSC? If so, how? My phone warranty has expired a long time ago, so I shouldn't care that much about triggering Knox though not triggering it would be preferred.
Which path should I pursue? Should I simply use ODIN and flash a STOCK COA CSC (Cosmote Romania) or STOCK ROM CSC (Unbranded Romania) from SamMobile.com with the latest version of Lollipop? Would this trigger Knox? Will it affect my all networks unlocked status? I mean, I won't have to unlock it after that, right???
OR should I ROOT my phone, change CSC, then UNROOT? If so do you know of any method to root Lollipop 5.0 without triggering Knox?
What do you guys think? Whats the problem with my phone? Why doesn't it work on 4G? Because of CSC? Or is it something else?
Thanks!
The best way to confirm the model # would be to boot into Odin mode and look there.

What do you mean? Can you be more specific? I already told you my model number, its N9005!! Do you want a screenshot?
Dear OP, have you tried the other Samsung secret code? *#2263# then program it to accept LTE only.
That's the only foolproof way to get the Note to connect to LTE. In my country I only get 2-3 of the 5 LTE bars, so the Note wouldn't automatically connect to LTE or immediately stoop down to 3G through the settings. That specific secret code and setting is LITERALLY THE ONLY WAY TO GET MY NOTE 3 TO CONNECT TO LTE IN MY EXPERIENCE.
If that still doesn't get your phone to run LTE, either your carrier is whack or your phone is, and no amount of Cyanogenmod can fix it because your hardware modem inside the phone might be whack and you can't really do anything if that's the case...

I have already explained that there is nothing wrong with my carrier because I switched my SIM card with my friend's phone who has exactly the same N9005 model and it perfectly works on 4G on his phone. The only difference I could find in our phones is the CSC.
As for the other suggestion you sent me, I already said that I've been to SERVICE MODE. The code you've given me does nothing on my phone but as I can see from your screenshots, it gets you to SERVICE MODE. I've already been there through *#0011# switched to LTE/GSM only or LTE/WCMA only and I've explained that it still doesn't do anything.
Can someone please answer me this? Would it help if I change the CSC? Could this be the problem I'm having???
It may help if your CSC is changed it can do no harm .

Ok, thanks! So how do I do this?
My phone warranty has expired a long time ago, so I shouldn't care that much about triggering Knox though NOT triggering it would be preferred.
As far as I know there are 2 methods to change the CSC. So how should I do it?

Booting into download mode will confirm the model #. Looking under the ROM's settings is not guaranteed to display the proper model #.
Both phones are running the same ROM, bootloader, and modem?

Yes confirmed, same model, same baseband, same everything. The only thing different is the CSC. So whats next?
Did you try changing the csc by dialling *#272*enter IMEI#? Not sure if this method will work for your model of note 3.

No I haven't I'm trying now. Wow if this works Im gonna buy you a beer!
It doesn't work! just my luck! I entered this code: *#272*IMEI-number# and pressed call button, it says "Connection problem or invalid MMI code."
I just tried it on my Note 2 and S4 and it works. Maybe the phone is not running a multi-csc stock ROM?
I don't have a note 3 to try.

Perhaps the code you gave me only works on older version of Android such as KitKat or whatever you have on Note 2... anyway Im using Samsung Phone Info app from Play Store and my CSC is XEF and under Available CSC Codes there is a bunch of CSC codes. Here I've made a sccreenshot:
From as far as I know there are only 2 ways to change the CSC: root or flash a different stock ROM
Yes, the note 2 has kit kat but the s4 is running stock lollipop.

Well unfortunately the code doesn't work on my phone. Anyway if you know for a fact, could you tell me this? Is it safe to reflash another STOCK rom from sammobile? Will it affect my phone in any way?
Thanks
Yes, it is safe to flash stock ROMs from sammobile.com.
I just flashed a local stock ROM and guess what, when I go to Phone Info app it still shows the same CSC! I still have XEF CSC, how can this be? Why hasn't the CSC change?
After flashing the stock rom, did you try the csc code I mentioned? Same thing happens when I flash a Rogers carrier rom over a Telus carrier rom. Once I select telus as the carrier from the csc menu, the Rogers app will disappear and the Telus app appears.
Ok after further researching I found a lot of interesting stuff so I'm gonna write it all down for other people who may need it in the future.
1 - If you have a multi-CSC phone and you flash a different CSC but which is in your "Available CSC" list but which you cannot choose or change without root, your CSC will NOT change. For example: I have flashed ROM CSC (Open Romania) on my XEF CSC (Open France) and guess what after the flash was successful and all, the CSC didn't change! It was still on XEF because ROM was in my "available list".
2 - If you try to flash a different CSC which is NOT in your list, then Odin will FAIL and softly brick your phone. For example: I got my phone bricked, trying to flash 2 CSCs which are not in my "available list": COA (Cosmote Romania) and DBT (Open Germany). In order to fix this issue all you have to do is to reflash YOUR OWN CSC, in my case it was XEF. Or you can even flash one of those CSC which are "available" or compatible so to say, such as "ROM" for example.
This is the firmware I currently have on my phone:
http://www.sammobile.com/firmwares/download/61565/N9005XXUGBOK6_N9005OXXGBOJ2_XEF/
These are the two firmwares I tried to flash on my phone, hoping to replace XEF with:
http://www.sammobile.com/firmwares/download/63441/N9005XXUGBOK6_N9005COAGBOK1_COA/
http://www.sammobile.com/firmwares/download/61464/N9005XXUGBOK6_N9005DBTGBOI1_DBT/
BOTH FAILED in Odin!
There are ONLY 2 ways to change the CSC on newer Samsung phones. Most guides online are based on KitKat 4.4 or older guides but for 5.0 Lollipop or even NEWER there are ONLY 2 ways to change your CSC:
1 - Root your phone and change the CSC. There are plenty of guides on how to do that online.
2 - You can avoid rooting your phone and use Odin instead, BUT accompanied by your stock firmware, you will also have to find and use a PIT file because Samsung as of 5.0 Lollipop uses different partitions for all the different regions. HOWEVER messing with PIT files is super risky and it can permanently brick your phone so its just better to root your phone instead! Dont waste your time trying to flash different regions/csc which is not in your available csc list, it won't work!
What can I say? Samsung is trying hard to block their users from changing their CSC... Why? They prefer their users buy new phones. Its pure greed yes but its what it is... For me, this was the last Samsung phone I ever buy. Im truly disappointed.
