How to enable LTE on Samsung Galaxy S4 I9505

Hello. I have Samsung Galaxy S4 I9505 and since yesterday we have new (the first in our country) LTE network. Now i have a problem - the LTE option is unavailable and i cant use my LTE sim. I have searched in google but did not find a way to enable the LTE.
I dont want to flash custom ROM so my question is can i enable the LTE option with ROOT only?
Please help.

Just check whether this app works or not! I have not tested it on Kitkat.. But I was using this on JellyBean to force LTE on my S4...

1. Make a backup of ur Internal Memory
2. Make a factory reset (Settings > Accounts > Back Up and Reset > Factory Data Reset > Reset Device > Delete All/Erase Everything.)
3. Conect it to Kies 3
4. Kies 3 will give u the info you need for know ur correct CSC. This 3 letters CODE will be btw parenthesis close CSC.
5. Knowing ur CSC, take a look for this firmware in Sammobile.com
6. Download and flash it with ODIN (Dont flash a "Black EDITION" if ur phone isnt it)
7. Enjoy

First of all you need to make sure that you have a LTE-enabled SIM. Ask your provider.
Then, you should test it first with the official ROM (for your phone&operator&country).
If it does not work with the official ROM, ask again your provider.
If it works, go ahead and install a custom ROM. check if you have the option from above post. If not, you have to try to install the right modem (that fits your country/operator/phone - sammobile is your friend).

You need to give some more info we don't even know what variant you've got or if your rooted or not. If you are then go into the systen/app folder and backup and delete lte config. Then go into hidden menu *#*#4636#*#* and pick lte/gsm/cdma preferred

3g model

Try this:
Go to Update center, open App Updates, and see if you have some update. I did not have LTE untill my Carrier got it, and I had to do an update.

Check what band you are connecting with your Xperia!

I found there are a lot of "debug" apps in the firmware for Z3,
and I'll introduce the most interesting one - "Tech Mode by Sony"!
With "Tech Mode by Sony", you can check what band you are connecting only with your Xperia.
I only confirmed "Tech Mode by Sony" aka TechMode.apk is avairable in the firmware for Z3 / Z3 Compact 23.0.A.2.98 / 23.0.A.2.105.
Here is extracted files from Z3 D6603 23.0.A.2.105: Download
[UPDATE]
You can get Tech Mode for Z1 or Z2 by flashing/downloading Customized UK ftf
How to check connecting band
1. Dial
Code:
*#*#*386#*#*
or
Code:
*#*#*585*0000#*#*
2. "Tech Mode by Sony" will be opened, tap what you are connecting.
e.g. If you want to check LTE band, tap LTE and if you want to check W-CDMA band, tap UMTS.

3. Check "Serv EARFCN" for LTE or "UARFCN" for UMTS
4. Open LG Space or some other apps such as EARFCN Calculator
e.g. Type number of "Serv EARFCN" to "Earfcn" of LG Space and click "Frequency ...".
Then you wil get band info like this:
For UMTS, click "UMTS Frequency" tab.
This is very useful if you are interested in network or unlocking bands.

Great! Tks for sharing this....

Anyway, tested on Z1 4.4.4 .133 firmware and all show N/A on the app. Some are display like IMEI......

Very helpful for me, T-Mobile would intermittently switch me to LTE Band 4 where signal was low instead of keeping me on Band 12 which gave me full signal. After disabling Bands 2&4, I am always on Band 12 now with full signal.

Not working for 5.1.1 on 6603

Great found!
Thank you so much my friend!!

It works on the Z2 with 5.1.1 ROM 264
Download the apk file, place it in system apps as 755 and reboot.. (you need custom kernel to write in system folder, or deactivate protection)
Thanks a lot
All other apps I've tried failed to read the earfcn Nr.

Hi @AndroPlus, I'm trying on a Z3C running stock MM 23.5.A.1.291 (booloader locked) D5803.
Both strings don't work. I mean, when I digit the last character "*" all the text I have digit (in the text dial number) is automatically deleted.
Is the apk working in this case?
Thanks

[OREO] [G950F/G955F] [Duos Also] Select a specific band on your Exynos S8 or S8+

The Samsung Galaxy S8 and S8+ were recently updated to Android Oreo, and among its new features includes a full band selector (replacing the old service menu that was disabled with the security patch of November / 2017)
This mode lets you choose a specific network (as does the test menu in AOSP) and also choose a band specified within all supported.
Now, the only known way to enter this menu is through an activity manager (Nova Launcher or Quickshortcutmaker for giving examples) and look for the com.samsung.HiddenNetworkSetting app
When you find the activity, you must execute it and the next window will appear:
https:// imgur .com/a/61DJo
Where you can choose the network mode. If you open the side menu, you will see the other 2 options (Band Selection and 5G SA Mode) then select "Band Selection" and the following will appear:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Here you can choose the available bands, and then activate the slider that says "Selection". In this way, the band chosen as the default (Remember that if you select only one of the bands, you will not have CA)
I remember again that this method only works with builds based on Android 8.0 Oreo (RAP or RB7)
I remember again that this method only works with the builds based on Android 8.0 Oreo (RAP or RB7) and I do not know if it will work on other models besides the international variants of the Galaxy S8 or S8+ (SM-G950F / FD and SM-G955F / FD)
That is all! For now, I will be alert to possible doubts, but I remember that this app is only available through a hidden activity within the Oreo update, and I do not know if it will be maintained in successive updates. I will continue informing.

Thank you so much

Thank you very much for this useful info and for some unknown reason I am not getting Band 40 in band selection menu even when I am 100% sure this phone support TDD band 40
