(base on GSMARENA)
This phone support the following 5G bands:
5G bands 1, 3, 28, 41, 77, 78 SA/NSA
however, my current phone sim need to utilize the Band 40, n257/n258 for 5G,
anyone know how to enable or activate these bands? Is there any MTK engineering software for this purpose?

I'd like to help but I'm not sure if the solution I would use would fit your needs and capabilities.
The (apparently secretly hidden) Android Activity it calls is apparently
com.samsung.android.app.telephonyui.hiddennetworksetting.MainActivityBased on what a free google free ad free gsf free shortcut inspector says
Activity Inspector
Having said that, I can bring up the HIDDEN Activity that allows you to select the bands available on the phone by calling the activity directly.
C:\> adb shell am start -n com.samsung.android.app.telephonyui.hiddennetworksetting.MainActivity
They even make apps that do that for you such as this one.
Network Mode Universal
See my screenshots below for my phone.
Hope this helps.

Thank you very much for your suggestion. I have tried all these and found:
Network mode universal - this is similar to *#*#4636#*#* for phone information.
Shortcut Widgets (+ Inspector), nothing shown in POCO X3Gt for band. it "maybe" work on your Samsung phone. Could not find any band information.
However, when get into *#*#3646633#*#* Developer option, it shows bands as attached photos, the Band 40 is greyed, no possible to enable it.

My response will be in two posts because I don't want to confuse you with the response about "Shortcut Widgets" so I'll take that separately as it's really useful only as a final step.
As for the band B40 being grayed, out, that is a problem.
My only experience with this band selection is on my phone, where nothing that is listed is grayed out. That is, for example, I don't have Band B28 on the phone (AFAIK) but that band is not listed either.
What I have that is listed, as far as I know, can each be checked.
So the fact you can't check a band that is listed, is really, I think, the problem all of the users here have to put our heads together to figure out why that is the case.
I don't know why you can't select Band B40 even though it's listed.
I can only suggest tests you can run to perhaps figure out why.
a. Anyone else with the same phone could run that test for you.
(Let's hope someone with that same phone will see this request.)
b. Maybe you can try one or two other "band selection" apps?
(This would eliminate it being a bug in that specific program.)
c. But the real problem may simply be the phone hardware doesn't support that band.
(I don't know any way around that.)

Ah. I think I figured out what I'm doing differently from you since *#*#4636#*#* doesn't work on my T-Mobile Samsung (we really need someone to test this using the same phone you have!).
My Samsung has its own app from that same outfit I referred you to
Network Mode Samsung
I'm guessing that your "network mode universal" is (maybe) giving you a list of all possible bands but (maybe) not just the bands on your phone alone like my "network mode samsung" is apparently doing for me.
If you can find a network mode app for your specific phone, that may show just the bands you need... but... you already ran the *#*#4636#*#* dial-code to bring up the hidden activity I think... so you may already have seen that the dial-code you gave probably brought up only the bands which are available to you.
Hope this helps. I'm NOT an expert in this. I would hope others with the SAME phone as you have can confirm our suspicions or prove them wrong (better yet).

At this point you don't need Shortcut Widgets + Inspector, as it's only useful to find out what the hidden activity name is, and even then, you only need to know the name if you're going to create your own shortcut to bring it up.
It's useful mainly for HIDDEN activities, because once you know the name of a hidden activity, you can bring it up in a single click if you know what you're doing (you have to create a shortcut to it).
As far as I know, it's the ONLY APP in all of Android that does what it does (although others may exist) so it's a keeper, for sure; but it only tells you what you want to know AFTER you've already brought up the "activity".
An "activity", if you aren't aware of what that is, is kind of sort of like a "pseudo public page" inside any Android app, which can be brought up if you know the unique name of that activity.
There are something like three or four hundred public activities in the Android "Settings" app alone, while most apps have a few dozen or so public activities you can call up directly, which means there are about a thousand or so, which is why you might need an app that tells you what activities are brought up when you do stuff on the phone.
However, if you can ALREADY easily bring up the band-selection activity on your own, you won't need this app to tell you that so I'd ignore it for now. Sorry if I wasted your time.
Appreciate very much for your reply with detail explaination.
I believe this Dimensity 1100 is prebuilt with all bands when sold to each different phone company, however, MTK will price differently base on the the number of bands given (enabled), some companies may sell its phone with lesser bands so to lower its price to make it more competitive.
This problem is hardware problem, so it could only be done with MTK special engineering software or some special code to enable/disable them.
This is just my suspicion, I may be wrong....

I hope you find someone with the same phone who can try it to help. Or someone who knows the MTK software. Good luck!

Now as open source!
Github: https://github.com/CazeW/RoamingControl
I'm releasing the source code as I no longer have a device that I can test the app with. Hopefully it will be of use for someone.
Roaming Control
Are you tired of having the R icon in the notification bar instead of showing the connection speed? Do you have a mobile plan that allows you to use it in certain countries like you were at home? Do you want to enjoy roaming in certain countries/networks but don't want to allow roaming everywhere?
Then this app is for you.
This started as a personal project for something that I needed myself but decided to make it a proper app for everyone to enjoy.
What this app allows you to do is:
Allow national roaming on virtual networks (to get rid of the R icon when being home)
Force phone into roaming mode on domestic networks that aren't the home network.
Add on which specific networks you want to allow roaming
Add in which countries you want to allow roaming (this will allow roaming on all the networks in those countries)
Dual-SIM support with separate rules for both SIMs (Lollipop 5.1 and onwards).
What this app doesn't do is just remove the R icon and show the connection speed.
If you add your current network or country when being abroad, you are roaming and it is your responsibility to keep your phonebill in check.
INFORMATION FOR USERS ON ANDROID PIE
I have tested this app with Magisk 18.1 and with the EdXposed Magisk module and confirmed it working at least on a OnePlus 6T. You may have to toggle the roaming system setting on and off (or leave it on) to get a data connection after a reboot.

Two questions;
1) Location of source code? I'd like to contribute.
2) Some phones (like Nexus 5) are having problems recognizing that they *are* roaming in certain circumstances. Can this be used to FORCE it into recognizing that it *is* roaming?

Shouldn't need to restart SystemUI, it should dissappear on its own after a while or if you can't wait, just toggle airplane mode on and off.

For now the source code is just on my computer, haven't yet looked into releasing it.
You mean that there are circumstances where the phone is roaming, but the R isn't showing up and the phone thinks it's on the home network when it in fact is on a foreign network (also not blocking the data connection as it should because of this)? If that's the question, then no, that doesn't currently work. It is however easily implemented.
Basicly what the app does now is to make the phone think it's not roaming when in fact it is (hence why it should be used carefully not to add the wrong networks/countries), but it can as easily be made to work in the other direction, to make the phone think it's roaming even though it is on the home network.
This is fantastic. I will test it on my Nexus 6P on T-Mobile when I am roaming again in Canada.
One related thing I have been hoping to see in an Xposed module that forces the data connection type display to stay on when the WiFi is connected as well. I hate that I cannot tell whether my phone is on LTE, H+, H, or GSM when I have an active WiFi connection.
@CazeW: great, thanks ! That is something I am looking for since a long time.
Will it work for Dual Sim too? (running CM12.1)

I looked into this and have now added the Force roaming option to the app. I have however no way of testing this myself so I'll be relying on feedback if it works. Also, if there's enough interest for it, I could add the option to be able to manually add the networks (like with saved networks) you want to force the phone into roaming mode on.

This should work on dual sim too but I don't have a dual sim phone to test with. I also suspect that the app might enable roaming for both sim cards which probably isn't what most people want.

Hi. My service provider doesn't cover all places in my state,so I have to connect to another service provider in my state where my home network is not available. Basically,I want to switch from my home network to the other network automatically,when my home network is not available. Can this app do that?
And,it does show the Roaming Symbol when I connect to the other network. Please help.

This app won't make your phone automaticly connect to that network. All it can do is that when you connect to it, the roaming symbol won't show up and the phone will think that you're on your home network.

If you don't mind my asking, is it a question of deciding whether or not you want to release the code, or a question of *how* to release it? If the latter, github is ideal. Is github.com/CazeW yours?
If you don't know how to use git, it can have a steep learning curve, but once you are into it, it is an indispensable tool that will change your life. I'd be happy to help you learn it if you need.

That would be an *incredibly* powerful option, especially for users of wacky MVNO's.
One other feature I can think of right now, which kind of is but isn't *entirely* related, would be to ignore signature checks on carrier services. The reason I say that it is related, is because the carrier service controls several aspects of network connection. For example, if you look at GsmServiceStateTracker https://android.googlesource.com/pl...telephony/gsm/GsmServiceStateTracker.java#894 you can see that a big chunk of the roaming control is tied to the Carrier Config, https://source.android.com/devices/tech/config/carrier.html
Just breaking the signature check on the Carrier Config would allow a lot of aspects of the network connection to be managed by regular installable packages.
Alternatively, the ability to inject a custom signature into the data read from the UICC would accomplish the same goal.
But of course, like I said, this is not entirely related, since it does break off from *just* messing with the network directly.

Alright, I'll probably implement it in the next version then.
Been wondering if I also should drop the National roaming option and just handle that with Saved roaming. In other words, just have the list of networks/countries where to allow roaming and a list of networks where to block it (put phone in roaming mode). National roaming feels a bit redundant and there are some issues with it. Say for example your phone doesn't recognize the MVNO as your home network, but it allows connecting to other domestic networks where the home network has no coverage. Enabling National roaming would make the phone think that the MVNO is your home network (which is good) but it would also allow roaming on all those other domestic networks (which is bad). This could of course be counteracted then with the list of networks where to block roaming but then it's starting to feel like its getting a bit too messy.

That is interesting and definetily worth a look at but for now it's a feature that would only work on Marshmallow. To get the most out of it, the hacking would also have to be done without the use of Xposed which unfortunately goes beyond my skills.

The way I see the national/domestic roaming option, is that it would be most useful on borderland areas that obtain coverage from one or more domestic networks and one or more international networks. If you know for a fact that you can roam sanely on domestic networks, but international networks will hit you where it hurts, then that would be an easy option to allow roaming on all networks with a matching MCC.
There are certain service providers here (Canada) where this would be useful, since they are not permitted any *actual* domestic roaming, and their local network has multiple MNC's from all of the past network acquisitions, yet they charge something like $5/minute for voice roaming in the USA. So a domestic roaming would allow them to connect to all of the different MNCs that belong to their service provider without risk of roaming on tmobile or att.

Actually, it would be beneficial back to 5.1, when the carrier privilege parts were added; https://source.android.com/devices/tech/config/uicc.html
And the beauty of it, is that the non-xposed part of it would actually *not* be a hack. It would just be generating a carrier package declaring the proper intents and privileges, and extending the proper classes.
Thanks a lot, working perfectly on Wiko Stairway (jelly bean), Now my wife can use our Femtocell at house
Your application works on the nexus 6p T-Mobile with purenexus ROM. My roaming was broken beforehand. Enabling it wouldnt get me data and the stupid r on the signal didn't let me know if it was even grabbing data connection nevertheless at what speed. Thanks a million.
I can't find a donate button in app or in your OP? Do you have a link for easy donations?
Hi everyone,
I don't understand very well what this app does. Can it be used to disable national roaming ? i.e. allow device to connect *only* to HPLMN even if other networks could accept us ?
So a little background on why I'm posting this. I have owned a G4 G5 G6 and V20, all on Sprint, and none of these devices can ever access the Phone Info section or "Radio Info" section as it's referred to on the Hidden Settings shortcutter App. I believe Sprint or LG removes access to this area on all LG devices. On all of the ones I've owned I can try and access the section but only catch a brief glimpse of it when I try to access using a shortcut app. It is always immediately covered by the same message every time which is: Note This application does not work on this device.
Now I just activated a V30+ a couple weeks ago which I received through Sprint's normal telesales channel and on this device I can get to and modify most fields in the section. I haven't seen other people posting about this so maybe it's standard for everyone with the LS998 Sprint variant and no one really cares or just doesn't have anything to say about it. If thats the case, my apologies for wasting everyones time with an unnecessary post .
If my access to this area is a one off situation and could help lead any developers or more avid tinkerers to any discoveries I'd be happy to test out some things together with anyone with more experience than myself. I've been holding off on attempting to unlock the bootloader and haven't done any PRL updates or resets just in case this access is worthwhile as I've been worried something is going to update and take away my ability to get into the section.
I've included some screenshots. I've cropped them to try and remove some of the more personal data but I think all the relevant sections are covered.
*** Below are some questions and thoughts I've had. I hiding the section it to keep things less cluttered for those that are just reading up but dont have any experience or opinion on the settings/functionality etc***
If everyone can already get to this section, have you changed your bands or modified any of the settings and what results did you see?? I've been tempted to switch up some settings and run some tests but I'm being kinda chicken about changing anything because I can't find any info on people using this menu to do anything except screw up their coverage. A few example seems to be people on different earlier LG models that select USA but live outside the US and then cant get it back to their countries settings.
Here is a list of things I would like to examine more, or try out in these menus. Maybe some of you have already done such or have the same questions. Any feedback would be cool on any of these things or even warnings or endorsements. I would love to learn a bit more about this area and its possibilities.
Under the "Set Preffered Network Type" option I would like to change the current setting of LTE/CDMA/UMTS auto (PRL) to one of the other options and see what happens. I believe this area is relatively safe and can be switched back to the original setting easily. I'd like to switch to Global Auto Mode, Unknown Mode, GSM Auto mode and LTE Only Mode and run some speed tests and see what towers its connecting to in each.
There are four toggle switches, one of which is grayed out. This is the Video Calling Provisioned Switch. Curious if this would possibly become accessible in another mode, or if there was something i could change in a database editor that would allow me to switch this to "on".
The only setting I did change was the one DNS Check. It was originally set to disallowed and I switched it to allowed. I dont really know what changes or abilities this added or took away and have not seen any difference since doing so.
The SMSC when Refreshed will give me an 11 digit number in "" followed by a 3 digit number. It begins with +1 giving it the appearance of a phone number. I believe this has to do with SMS provisioning but am unsure and have not modified the info here.
One part I am very curious about is a grayed out button labeled OEM-specific info/Settings. I have searched like crazy just to try and find some info on whats behind that button and got nada.
In the additional menu section (the three dots) I have an option to Select Radio Band. When Pressed it takes me to a menu which sats "set GSM/UMTS band". This is the area I have found little about other than what I mentioned earlier about people getting locked out of their country settings. I have not touched this setting.
The IMS service Status of my device seems to not populate correctly as I'm listed as not registered or unavailable for all sections as seen in the picture attached. I could swear that a week ago I was showing "registered" but if so thats no longer the case.
Thanks in advance for any feedback.

Do you mean the ones within thd expanded part of the phone info section? If so, I've checked those out and they are blank. Screenshots attached.
So enough people have seen this post now that someone with a V30+ should be able to confirm whether or not others can get to these settings.
Anyone?
There is several other threads about this already. I found them while trying to find a way to get more ?? bands working on my India based phone. Nothing new i don't think and none of it actually helped, for me at least. There is a dialer code for it but i can't remember it.

I'd like to hear what you tried out and see what changed and what stuck and what didn't. . Maybe we can get your phone working better here in the states if we team up on the problem... I know my avatar shows I'm a junior member but that's because I don't really post often, but I do plenty of reading and tinkering myself and I have been in the Telecom business for about 15 years. I'm not an expert or making any guarantees but I certainly don't mind helping out a fellow member here if I can.
Do you have your MSL code? I have mine so if you have yours maybe we can take a look at how my phone is provisioned in the ##data# menu and get your bands setup the same way since mine should already be configured to the proper bands for the U.S. Between modifying that area and making some changes in the Radio info section that could do the trick for you. Let me know if you'd like to work on it and we could PM or you could reply with a run down of what you've tried and how you're setup now and we could go from there.
Cheers.
*#546368#*930#
Field test. LTE band selection. Selecting any band from the menu just makes it completely lose cell signal. After selecting a band it just either says success or fail.

Ok so that dialer code doesn't trigger anythibg on my model. I also tried replacing 930 with 998 and tried replacing the *# and #* with just ## and no luck. But no worries.
I'm thinking you may need to change your settings in two menus in order for the new settings to work together. If you go into your Data menu (##data# or maybe *#data#* on your model) and update the information there to match the ones I am attaching in my screenshots and then go into the Radio Info menu and select a similar setup to how my device is provisioned you may see some success.
Thoughts?
You would need your MSL code in order to change the settings in the ##data settings....
Where do i get msl code?
Neither of the data dialer codes are working for me.
Oh those settings are only for cdma phone?

There are a bunch of tips and tricks to find your MSL code posted throughout the boards, but I have only ever got mine from the carrier. If you call customer service you can usually talk them into giving it to you, though their policy on this is to not give it out unless your phone is fully paid for / out of contract. If you tell them you are working with a tech in a store and need it for provisioning they will normally give it to you.

Hey guys,
neither my Wifi Calling, nor 5G doesnt work on my Redmi K30 Ultra. Not sure whats the deal behind it, maybe its the Mediatek chip or that it doesn't pass Safety Net or that its not made for Europe.
Anyway: Can we hack this somewhere? Maybe modify some props or something and magically make it work?
Thanks so much! <3
More info: I've done the usual stuff like activating Wifi calling, VoLTE and 5G in settings and also disabled carrier check via number code. I also tried all 3 big carriers in germany
Telefonica/O2: Nothing works
Vodafone: LTE "works", it shows an HD icon at the top but Wifi Calling doesnt work and 5G doesnt either. Shows both VoLTE and Wifi Calling as enabled in Phone Info.
Telecom: Nothing works, but it shows in Phone Info that VoLTE and Wifi Calling is enabled.
@Mirardt
Per description the phone supports Wi-Fi calling, VoLTE and LTE, so I think it's not a chipset problem. Carriers will typically sell these data services with smartphones as part of a bundle.
I guess it is a problem with carrier ( data plan chosen ). You can try to contact your carrier and check if everything is correct from there end.
In no case your issue has something to do with SafetyNet API what is an anti-abuse API application developers can implement.

Hey there, yes everything is activated from the side of my carrier and also i spoke with vodafone technical support and they activated everything they could, reset the network etc.
Also both VoLTE and Wifi Calling work on the iPhone with all of the cards. So it has to be something on the phone.

Sometimes they just block per device model (supporting only phones that were certified for their network) and you need to convince them to let you in
Or, you could (again) play with props like ro.product.manufacturer and ro.product.model to pretend you have some fancy Samsung - bcs if it shows enabled in the settings, it's likely blocked at the time of handshaking and negotiating to use the service
It's also possible to capture the UE Capabilites offer (see attachement for my LTE part) and response - I will try to find where was the URL with know-how and instructions

I talked to a vodafone technical support guy and he said that everything is fine and open from their side. Also my phone runs with your fingerprints (Mi9T) for a week or so and it didnt change anything.
Do I understand it correctly, that all the methods you linked there only work with Qualcomm chips? Cause the K30 Ultra does have a Mediatek chip. :cyclops:

If the doc is only about Qualcomm, you will need to Google for e.g. MTK bands UE Capabilities
But MTK was usually more open, people were even able to easily change IMEIs.
There used to be a code for MTK Engineering mode, with options to enable bands and so

Ok do I understand correctly that UE Capabilities are parameters that my devices has that sends information if it can do 5G or VoWifi and so on?
After a bunch of Apps that refused to work with my phone (unknown device not supported) I did found one that looks promising. The problem is that I have only littly orientation and understanding. Can you see what setting might be relevent and maybe if we can get those UE Capabilities changed inside the app?
What I tried is switching the "Entitlement Status" of Wifi Calling on "Enable" (It was disabled as I opened the app), but nothing changed. The Entitlement server is left blank, maybe that could help?
Also I just swapped every possible thing from "false" to "true" inside ePDG Config, but it didnt help so I reseted it.
If you (or anybody else) could have a look and give me some direction I would grind it out myself!
edit: Upload doesn't work on this forum somehow, strange. Here is the Gdrive link.
Ok I just looked through every single option their is, screenshoting everything that seemed relevent.
There is band information that seems like it is what you mentioned and it is editable! @zgfg
Also a couple of other direct mentions of VoLTE, like props in IMS settings.

Very interesting, (as expected) you can control many things on MTK ( too many)
For LTE bands, I think you need bands 1,3,7,20 and you don't need TDD bands.
For 5G, googling tells me that for Germany you need: n1,n3,n28,n78,n258.
Suggesting you to double-check for your operator and enable what's missing and reboot.
B20 might be available in a shopping center, or dense busy district
In the Call* and IMS-Registration* screensots, are all those params enabled or you need to open another screen for each (modes)?
On the IMS, I would put VoLTE to Default, not to CMW500 - seems to be a mode for testing equipment.
Also, you could try SMS over 3GPP or 3GPP2 (that means SMS over IMS but when you register to IMS), but check does it still work over cellular
Last screenshot says that it's not registered to IMS, but seems there are additional settings for IMS authentication (that's about registering to IMS - VoLTE is an IMS service)
I pretty much tried everything out you suggested and it didnt work. Thats why I waited to work on that until I freshly reset my phone with GApps Pico and I did that yesterday. During the Installation process there are 2 question came up:
1. There are Google Carrier Services I can install through play store. No clue what it is, does it matter?
2. I have found multiple interesting sounding apps in system/priv-apps like "engineermode", MtkCapCtrl", "MtkTelecom", "MtkTelephony Assist" and "MtkTeleService", the only one I can find in Apps is "engineermode" and i didn't manage to open it. I tried to install the other apks but it didnt allow it. Anything that might help us?

Tried everything but it made no difference. Also tried IMS test mode on with and without SMS.
Also it keeps saying its not registered in PhoneInformation1.
Should we try to change those numbers in the VOLTE settings to something like this?
Edit: I activated logs telephony logs and somehow got a bug report without even calling somebody. Uploaded it.

wifi calling hardly ever works on foreign phones but my k30 ultra gets 5g on tmobile in my state.
Wifi calling hardly ever works on foreign phones but i get 5g on tmobile in my state , the k30 gets 3 bands that havent been listed , just get a mtk engineering mode app to see what bands you can work with.
In this video, at about 05:18, the steps for setting signal (5G, LTE) is shown
On our brand new Samsung S21 5G (two AT&T phones directly from Samsung) this setting does not exist
Is the OS Build update missing or something else ?
I believe this option is only available for the unlocked version.. Carriers are probably hiding this option
Good day.
If you want to change the band even if it's hidden, use this app.

This app will help you access hidden network settings for forcing band selection

Is there any downside to installing it, disabling 5G (? possible ?) and then uninstalling app ? IOW - does disabling band require this app to remain on phone permanently ? Constant tweaking to keep settings ?

Thanks to paolotheking and this thread about an important secret code for the Velvet and other devices:
LG Velvet Hidden Menu code
Enjoy: #*462633*#900# Works with G900EM
forum.xda-developers.com
I could finally activate the 5G network capability of both my LG Velvet and LG Wing, European versions.
I have an Italian (ITC) genuine SIM unlocked Wing LM-F100EMW with latest Android 10 V10k-EEA-XX installed.
If you hit with the phone dialpad this sequence:
#*462633*#100#
it will lead you to a hidden menu where you can find all sort of information and tweaking options.
You have to choose "Field Test", then "Modem settings". You will have here many things you can change. Go to "RAT Selection", "SIM 1 Mode" (if you have only 1 SIM or if it's the one you want to go up to 5G speeds), it will give you many more options than the ones you find under the regular "Network settings".
So I then hit the "GSM/WCDMA/LTE/NR5G" option. I now have up to 5G automatic network selection!
Only issue is that under the regular Mobile Network settings, "Preferred network" states now "26" and if I want to see what other options you have, it only lists the options up to 4G preferred and it will go back to 4G maximum if you choose it. So you have to go through the hidden menu again to activate it.
I also tested that if you power off the phone, 5G maximum stays activated when you power on the phone again, good to know.
You may also try to tweak your 5G bands by selecting them in the corresponding menu "Band Selection" in the "Field Test", "Modem Settings" menu. Some of them might not really work though, as it might be hardware related depending on your model.
Hopefully it can help people finally being able to use the 5G network of their provider with the Wing, Velvet, and possibly other LG 5G phones like the V50(S) and V60. You just have to put your model number at the end of the secret code ...#900# for the Velvet, ...#510# for the V50S ...#100# for the Wing, aso, if I understood it good.
Enjoy!
I tried your suggestion above but field test is missing on my device (LM-F100N, unlocked SKT model). Any suggestions?

Interesting, this means that the carrier specific models, for Korea at least, don't offer the Field Test option. We have a discussion in a thread about the V50S eith the same issue (another secret code on this model for the hidden menu).
You can try 5457#*100# that works for the V50S to enter another menu where you can tweak frequency bands, preferred network, etc. The code might be different for the korean Wing / Velvet though. You might have to search the web or xda and try the different codes you find. Just remember to always use the LG dialpad to enter them, it won't work on the google telephone app for example, or at least it doesn't work on the V50S SKT that I have.
Do you have the up to 5G preferred option available under the Network settings? This option is available for the V50S but the problem is more about the 5G frequencies available on this model. It uses the n78 band that we eventually will have here in Europe, but it doesn't have the n28 5G band that is starting to be available in most of Europe. And no way to activate anything from the above mentioned hidden menu.

Code is right, but for the Verizon model probably not. Try to search the web/xda for secret codes on LG Verizon recent models. Usually the last number in the code is your phone model number (100 for the Wing). So change the last number of the code to 100 before trying the code on the wing. And use the genuine LG phone dialpad to enter the code!
Let us know if you find any useful code, it might help other Verizon users.

The code works, the 5g preferred option is also available. However, I still can't seem to get a 5g signal even though all networks in my country are using the n78 band. Is there a possibility that SKT has locked the 5g frequency, even though I could use LTE? This variant also has a dual sim tray but looks like it was disabled.
Has anyone tried flashing other regions firmware using edl mode?

Hi Vuche,
When I first tried this, it worked perfectly and I was very happy. But recently I was wondering, hmm I've not seen 5g recently, and I realised that whenever I reboot the phone, it reverts to becoming 4g only
Do you have any tips on settings I could change to make it permanent? I'm not sure why it stays after reboot for you, but not for me.
Yes, I.'ve had the same thing happening on both Velvet and Wing, and I think it has started with one or the latest firmware update.
Apparently LG is following our threads here on XDA and really don't want us to have a good experience with their Last mobile phones...

I just dont understand why a phone marketed as 5g, has that option hidden away!!
Do you think there's anything in the hidden menu that could make the 5g function permanent? (I'm not sure how you discovered that menu in the first place?)
It might be that there's some faulty/unfinished hardware used in our phones. Or it's a financial issue, like a licence fee. Whatever the reason, they might unlock everything soon, ...or never!
I use a projector at home (not LG) and I won't buy their TV's anyway. But one answer to their policy could be not buying their other products anymore. They are bad at marketing anyway, so they might die by themselves. Too bad though, they have very creative engineers!

You have apparently an SKT (South Korea Telecom) model. It doesn't seem to offer you the possibility to activate other 5G bands than the n78. In Europe for example, n28 and n78 are usually used by network providers. The n28 is the most commonly used band as it's easy to upgrade from 4G LTE and it works on larger areas. n78 is mainly used in densely populated city as it works on a higher frequency.
But don't worry, 4G/4G+ is still fast enough until they develop the n78 band further out. At least compared to n28 speed.
Possibly unrelated but does this mean I can use an International AT&T unlocked Wing LM-F100VM on TMobile for example? I bought what was claimed to be network unlocked, "just throw in a SIM card and it'll work on any network" but entering the IMEI onto TMO's website and talking to their chat people tell me that basically 5G won't work :-/
International phone working on US networks?
So back in the day I used to bake my own ROM's and whatnot but I haven't done that kind of stuff in years. I finally upgraded from a Sprint SM-N900P Note 3 to an AT&T LM-F100VM LG Wing that I bought off eBay. Took the Wing to T-Mobile today and...
