How to enable LTE only mode? Urgent help needed.

I was earlier having Mate 9, in which i was able to use to switch to LTE ONLY mode very swiftly using netswitch app, to use Vodafone India 4g network. My mate 9 used to show 4g only signals and i was able to use data only network as my area was having issues with 3g network.
Now i got a new Note 8 Dual sim exynos model. Using some third party apps from play store, iam able to select LTE ONLY mode (only on the sim which has been selected as Calling sim). But it displays no signal after forcing to 4G only mode.
Please somebody help, so that i can use Vodafone India 4g network.
In the same area, when i use the same sim in a snapdragon Redmi Phone, and select the LTE only mode using *#*#4636#*#*, instantly that REDMI phone switches to LTE mode and shows full signals and i can use 4g data.
Somebody please help.

Sir, you are the man. Thank's a lot for this lovely app.

You shall be mine as well.
Especially since the app "shortcut master (secret codes)" stopped working for me under Android Pie, your app successfully calls the network mode selection menu.
Many thanks for that great hint!

Link is not working pls tell me the name of the app

You may use this link instead.

How to force 4g LTE on sim 1 or sim 2 as needed?

I am using the dual sim Exynos version of Note 9 and want to be able to force 4g LTE on either of the two sims as needed.
Can someone please advise how to do this on an unrooted phone? Thanks

Anyone?
I also found no solution. I think it's possible without root but no one is updating the Phone Information Apps. We need to get access at phone information 2 and not only on 1

Mine are both 4G / LTE. Inever need to switch the Sims around. Whichever I choose for days gets LTE. this is different from what I had in the Note 8. I was pleasantly surprised. Therefore it may be a settings issue for you. I have the Note 960F/D

you may try quickshortcutmaker app on exynis version and follow instructions in video
https://youtu.be/AdGAB4qRvYA

I feel like the Tasker App could handle this easily.

I dont understand the actual need.
Simply changing preferred network mode from LTE to 3G shall do to stop LTE on any sim.
I use LTE on both sims for calls
I use LTE for data on specific sim by making it as preferred sim for data.
Settings -- Networks -- Sim card manager shall help in these settings.
I am on exynos N960F Indian firmware.

You don't understand the actual need ??
So i will tell you
On my work i am located in a big Hall underground. The Provider i need down there is only coming in with -110 dB and less which is one LTE Bar. If i leave Automatic Mode it switches always in 2g Mode because of much higher Signal. So to get a nice experience and have LTE always available there is no other solution. The same kind of problem is on my other LTE Sim when on different Locations during the Day ! So i have no time to always switch sim cards so that sim2 is forcing lte !
And off course no one else knows this and so i benefit of this extremely fast connection where all others are crying because of no 4g connection

OK understood.
Did not you get one UI already which has option of LTE only selection too for network mode.

Negative. Here the German Rom (dbt csc unbranded)
Has never got LTE Only mode in the menu. This is also for all European Roms. I have had this only when using Root and Custom Roms.
Because i use many banking and streaming apps it's not possible to root this time. Even with Magisk Hide they will not work.
If i could i would have rooted long time ago. This is getting me Crazy really

Sorry but are you reading my Post?
I am talking LTE Only on Sim Slot 2 of any Samsung Phone out today. All the LTE Only Apps or the Phone Info Menu where they lead you is only working on Sim Slot 1.
I am sure there is a dial code like the one it gets you to the Phone1 Information Screen where you can change the bands. But only for Sim 2 (Phone info 2) on Samsung.
So again LTE Only on sim Slot 2 on Samsung Duos Versions is not Possible @ the moment without Root!
If there is any Dev out there you would be the first One to create an app where Phone INFO 2 is possible to change! Or just find the right hidden code for that i know it's there like the Phone Information 1

Hi,
There's an option to force the selected APN to LTE only but I don't know if it will behave like you want to.
What's great is that it's per SIM so you can try any combinaisons.
Deselect "undefined" and select only the "LTE" one (screenshots).
I expect that if it find any other bands getting a better signal than LTE, it will just let the phone loss the signal and not trying to catch the LTE one, but you can try.

Hey thanks for that. I really was in hope this could work but that would have bean to easy. Unfortunately it's not changing bands after deselecting undefined and than choose some network mode it remains to the same band but it looses the mobile data symbol (but still remains in same band).

This code and all Codes are not working on European Samsung Devices with Android 9 .
I Even Rooted my Galaxy Note 9 and all the hidden codes are Not working ! Even Samsung Phone Info App or other Apps are not working with Latest Android 9.
Only way is Root and Custom Rom like Alex Dev Rom where the CSC is Modified. There it was possible to change both Sim to LTE Only ! But as told before with Root
i loose to many services which are detected even with Magisk . So my next Phone will not be Samsung anymore because of that.

Note 8 (SM-N950F) Lock network BAND

Hi guys,
I have rooted my note 8 with deluxe ROM to access hidden network setting option to lock specific band of network. As we know that, Hidden network setting option is disabled by Samsung but, I rooted my device and download apk of hidden network setting and placed in system with help of root explorer. Everything went perfect. Now, I can access section where i can select specific band and lock it. I access it with Shortcut Master Lite. But, When i tick on specific band and toggle the selection button then it shows message success. Immediately my network change to my selected band. I can check from *#0011#. But, if my phone remain in stable state for few seconds then it automatically switch to another band. Which mean it didn't lock to specific Band. When i go back to hidden network setting, there is no tick on my selected BAND but toggle but still says that i am on selected band option instead of LTE ALL. I am using India Jio Sim card which support Band 3, 5 and 40. I get very good internet speed on 3 and 5. But, It automatically switch to Band 40 when its remain in stable state.
I want to lock it to Specific band only. Can you help regarding it. I am using deluxe ROM with Android 9.
Thanks

Hello, were you able to fix this problem ?
Am going through the same atm

I'm facing the same issue on my N950F. Don't understand why samsung locked this on the Note 8, most new phones allow this setting. Any way to work around this with root ??
Edit: this is what worked for me https://forum.xda-developers.com/t/how-to-lock-lte-band.3681480/#post-74325453
TL;DR: Get org.vndnguyen.phoneinfo (no longer available on the play store), and run ServiceMode as root. Follow the guide above to disable unwanted LTE bands. Finally a solution that works for devices which Samsung disabled the "Band Selection" menu method (blue background issue).

Xiaomi's/MIUI's Network Band Prioritization

Hello guys,
I'm using Mi9T Pro with Stock EU rom MIUI 12 version 12.0.4
I have this issue with Xiaomi regarding how the system handles prioritization of Network Band when it comes to using Mobile Data connection.
We know that we have options to prefer 4G, 3G or 2G. But it doesn't define which specific band. Like for example, 4G can be 4G/LTE or 4G+/LTE+. These 2 networks seem to be the same but these actually have different network bands
The question is how does Xiaomi system prioritize which band to select?
Does it prefer the one with higher signal or the one that pings better.
I have this question because as I have experienced, Xiaomi system seem to prefer the one with better signal regardless if it can't even pull any data. In short, it will keep connecting to a network with a better signal strength even if you won't get any internet connection out of it.
I've been noticing this when I set my phone to 4G preferred in my location. When signal indicator turns to 4G/LTE. It may seem to show you that you're connected to the internet but you can't really browse anything because there's actually no data for that band. But when it turns to 4G+, that's when I really get to connect to the internet.
And the biggest problem is that the system prefers to connect to the 4G band. That's why I'd prefer using 3G network because I have a more stable 3G+ signal here.
Another thing that's really disappointing is that my other phone OnePlus 5T handles this well. We share the same APN.
Sadly there's no band selection in *#*#4636#*#*
It would be glad if anyone could provide a better solution to this.
Thank you!

4+ g usually means (specially on Xiaomi phones) LTE Advanced Carrier Aggregation where no other/different bands are used but instead the phone is in parallel attached to more than one 4g band. As such, it increases the speed (and maybe, in your case provides a fail-over?!):
https://www.gizbot.com/mobile/featu...ifference-between-4g-4g-explained-053769.html
However, there is another question why (on that place) you have strong 4g signal with no Internet, so that when your phone switches to CA and in parallel attaches to another 4g band (maybe with a weaker signal) it obtains Internet connection over that second band
At least to better understand on which band (at which place and which base station) you have a 4g signal but with no Internet connection, install an app like Network Cell Info Lite, LTE Discovery, Net Monitor Lite). I think with Net Monster (all apps are on Playstore) you can even see on the map where is the base station you are attached to
If your phone is rooted, you could use Network Signal Guru that will show you, in case of 4+g all bands you are aggregated to with their signal strengths, base stations locations, etc (apps above would always show just one, primary band):

Ohhh thank you for this explanation.... Someone actually mentioned aggregation to me also. This helps make me clear up how Xiaomi does this and that. Does this mean force selection of network band won't work on Xiaomi devices?

I'm pretty sure that with MIUI 11 there was an option to disable/enable 4+, but on MIUI 12 (12.0.2 QFJEUXM) there is no more that option
I don't know of other options (except to prefer 4, 3 or 2 g), specially about selecting bands

choose band mode

Network Signal Guru I think this app has an option to choose which bands to enable/disable.
Somewhere in the settings.
