Just in case you do not know it, the carrier that you use, need to support it in general, and the carrier also have to decide that they want to support on that phone model.

Is the menu inaccessible/hidden entirely without carrier support? I can find the shortcut to "Enhanced 4G LTE" by searching the settings menu, but when I try to follow it I end up with the normal network settings (without the Enhanced 4G LTE option)
My phone is the TA-1004 version

*#*#4636#*#* key combo will get you access to enable VOLTE/Video calling over WIFI.
Be careful of what you change.

Hello,
Thanks for sharing that I fo, I know that secret code but don't stay on VoLTE, seems as carrier have to enable that service on sim card, and they make available this services only on Samsung S8, Samsung S8+ and Xiaomi MI6. They are still on test with VoLTE

I think it depend on carrier.
I have two carrier, one doesn't have VoLTE and another have
In Cellular network settings, you can see one have "Enahnced 4G LTE Mode", but another not.

Unlocking "Only LTE" mode in Honor 9 lite

Hi friends, we all generally hate it when network automatically switches to the mode in which phone gets strong signal. I mean we really don't like when phone automatically switches to 3G or 2G mode from 4G when the signal of 4G is weak. Since there is no "Only LTE" mode in our device (Honor 9 lite) we need to enable it. How good it'd be when we could enable it without rooting.
Here's the process:
1. Download "Settings Database Editor" (attached below)
2. Open the app
3. Find "hw_networkmode_preference"
You will see its value like "9,3,2,1"
4. Edit this value as "9,3,2,1,11"
5. Save
6. Reboot
Now go to settings > wireless & networks > mobile network > preferred network type
You will see so many network options unlocked.
Select "LTE" to stay in LTE mode no matter how weak 4G signal you have there.
* Root is not required*

Hi, I have got Honor 9 Lite Indian version but when I am using a US based SIM, only Data & text are working and I cannot make & receive calls. Appreciate if anyone could guide on how to resolve this.

Whoa bro it worked! ?
Got any other cool tricks with this app?

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

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.

Any way to set data to use LTE only (and not 2G/3G)?

I'm missing the option to set my device to 4G only. Under "Settings" -> "Network & internet" -> "Mobile network" -> "Preferred network type" I can switch only between "2G/3G/4G" and "2G/3G". I miss further options and especially to set it on "4G" or LTE only. Because my network provider is pretty bad at 3G but quite good at 4G, even when 3G signal is much stronger and 4G signal is weak.
I don't care if I can't take voice calls in this mode.
Edit: I see there are apps on the store to do this. Though would be great to do it within the ROM.

My old phone did, when LTE signal was weak (but still available), and I assume, any other phone will do so as well. But data was much more reliable within 4G than 3G, even when signal was weak.
I play a gps-based online multiplayer game and whenever someone complained about bad data, I hinted to set their phone to LTE only.

Anyone knows the actual difference between 4G and 4G+ icon on top bar? I've got the international version with MEO provider (Portugal), and I never saw the 4G+ icon active.

4G+ Means LTE-Advanced aka True 4G, and it is faster than 4G. The only difference is the maximium theoretical speed, bandwidth and minimium latency you can get. 4G can reach speeds up to 100Mbit/s, while the 4G+ (LTE-A) can reach up to or over 1GBit/s, with less than a few milliseconds of latency.

Question Not seeing Network Preference under Enable Wifi Calling Tmobile USA

Hello
I just got this phone and set it up. Its a Global version 13.0.4 SKDMIXM.
I am on TMoblie USA - the phone is working great on LTE and 5G .
I am not able to see the Network preference under wifi calling where is can select Prefered Wifi Calling.
It appears that its running on default Prefered Cellular - because I can only see the VoLTE symbol on top.
Can someone help me in fixing this configuration to select Prefered Wifi Calling ? TIA

Hello, I'm using a 11T Pro Dual SIM India model with India SIM in Slot 1 and TMO SIM in Slot 2.
I have not found the specific setting to make Wifi Calling "Preferred" but, my phone does indicate Vo WiFi even when I have Wifi connected and Mobile Data turned on too once Wifi Calling is enabled as below.
Apparently the Voice Over WiFi Settings (at least here on my phone) only show up for SIM 1, does not show for SIM 2.
Attached are sample screenshots where the Settings are under SIM 1.
Steps to get there-
Settings > SIM cards & mobile networks > Click on SIM 1
All the way down, last Setting is "Wi-Fi Calls" to enable "Make calls using Wi-Fi".
Hope this helps.

Operators can disable this menu if they want to lock you onto Wifi preferred or cellular preferred. Does this only happen with this phone or does it also happen with the SIM in another Android phone?

There's a possibility of TMO-US not supporting WiFi calling on the Xiaomi 11T (Global), perhaps.
Although, I have been using various Unlocked phones (Nokia & Samsung) on TMO-US for the past few years & have practically never had issues with WiFi calling on any. Shall have to test it once I'm back. Won't be for some time.
Is your phone on the latest firmware? Try updating it to check if there's a new update available
which hopefully can solve your issue.
Couple of options to test, in case you have not already tested them-
a) leave WiFi Calling Enabled then disable the VoLTE feature and check if WiFi calling works?
b) disable Mobile Data, WiFi Calling enabled with WiFi connected and check if WiFi Calling works.
c) some users have had to ensure their E911 address is correctly in place on the TMO account too.

I had a working One Plus 6 - so I know TMO has VoWifi - I use it a lot due to poor reception at home .
The current workaround to force VoWIFI is
Turn On Airplane MOde
Turn ON WiFi only
then it works in VOWIFI with out any issues
I know I am missing a menu Item that can toggle this setting . I would prefer having that setting but its not a breaker for now . The phone works with all the Network features of TMO , LTE , 4G , 5G etc . No visual voicemail thats all.
Thanks
