I have H850 EU model. I was checking the hidden service menu *#546368#*850#. Under that I went inside the Field Test->GPRI VoLTE/VoWiFi->UX.
These are the following options listed:
1. gpri_display_volte_setting
2. gpri_display_hdvoice_icon
3. gpri_display_vowifi_icon
4. gpri_display_vowifi_setting_options
5. gpri_display_vowifi_setting_preferred
All are checked. Still I don't see the VOLTE option in Call Settings/Mobile Networks/Notification Panel.
Any idea on how to enable this? Please note that 4g does work. Only that VoLTE is not enabled.
I have attached the screen shot as well for reference.
Does anyone know how to enable wifi calling? These options don't do anything when enabled.
Same issue here..
But somehow sometimes i get carrier sms even when there is no volte. But when i try to send any message... It always fails
I have tried updating the ROM to Android N. Still VoLTE and VoWiFi is not available inspite of all the above listed options selected.
We need proper ims settings according to ur region..
When i ws having Samsung s6... I need to flash csc files in international roms according to region/carriers for volte. There ws a thread in s6 forums containing csc files for all the regions...

But that is for Samsung mobiles. At least my G5 does not have a CSC folder under system. Not sure if I can create one and add those values. Also, when I try to the IMS setting it says "Trace module is currently empty". Any suggestion is appreciated.

Csc is for Samsung, G5 directory must must have some other folders or files having values for volte.. Only developers like ( @xpirt) can help us.
I remember when i flashed Samsung a9 rom in my s6.. CSC flashing doesn't work. So at that time a developer provided an app named ims settings.. In that app i changed some values which were told by same developer. Nd i got volte
Sry for eng
Same problem here :/
I have the same problem here. Although it wasn't my problem until I flashed fulmics and my device got locked out and had to format everything including system. Previously my LG G5 was working absolutely fine with voLTE without any app help. I remember getting a vodafone splash screen on my phone before flashing 'autoprime's' rom for g5 which gave me simple lg splash screen. I am sure this is due to region wise settings but if I find my region rom that'd solve my problem.
Hi,
Following a tips in an android newsblog (In France), i was visiting the *#*#4636#*#* menu.
By curiosity, I tap on the menu "Sélectionner une bande radio" (choose a baseband).
I've only a "United States" choice but after did nothing. I lose all my phone network.
Just the data work and the sms.
What can I do to this ?
I think to flash a baseband firmware but where can I find one ?
Thanks for everyone who could save my phone

Switch your radio band back to automatic? Go to *#*#4636#*#* and click the overview (3 dots) at the top right. Hit select radio band, then hit automatic. Reboot phone.
Thanks but no auto option for me :/
I've done a Factory reset but no change.

I try to put network in Only 3G or 2G and got nothing. Maybe that's why there's no call but sms and data. No VoLTE in France.
When selecting United States band (that I didn't want to do), i break the 3G and 2G connection.
Hi,
I've speak with the Motorola support in France.
In the hidden menu, i've selected the united states band so now I only received the LTE (the only which are the same than here). No 3G and no 2G.
And because We've got no VoLTE, I can't use calls.
And no method to revert this process.
Go in warranty...
Actually there should be a way, because I have the selection:
Automatic
Europe
Automatic
United States
You probably have to update to a current stock ROM so the modem firmware updates and you might be able to select a different baseband... all theory but if you still have the phone, it's worth a try.
edit: I'm using a custom ROM, so I may be wrong.
For you there is no way of using a custom ROM without having problems with warranty.
If still relevant, I made the same mistake with my stock Moto xt1650-03 and the only way managed to restore signal was by using fastboot erase modemst commands. Though I have seen people not recommending this method, it worked for me.

Thank you so much for offering your help.
Actually, it is not a difficult process to extract that file.
First thing needed is to install QPST and enable the phone serial port.
After that, you need to open a program called EFS Explorer and then extract the files.
You can find a video that explains the process here

After installing the Qualcomm drivers, you will see LG Diagnostic Port, and LG Serial Port in device manager. Manually update/replace the serial port driver with Qualcomm HS-USB Diagnostics 9025. Then in the phone hidden menu you have to turn off the diag port under SVC, Port Check Test as shown in the video above. Then it should show up in QPST and EFS explorer

I have all the carrier_policy.xml files, TM VM EA. But I have some questions first. In which country and what is the name of the Carrier? The only reason I'm asking is: As far as I know, nobody in the US has crossflashed (most have been crossflashing the lmv600am) and really been able to get a 5G signal. Yes, I know it may have the 5G moniker on the taskbar but using Netmonster tells a different story, as do other tools. It's 4g masquerading as 5g. For example, on the v50/v60 on tmob network, using b66 shows it's 5g when it really isn't. When you crossflash with a KDZ the efs partition is not overwritten nor should it be because it contains imei info. Any file (carrier_policy.xml as an example) in the efs to be change has to be DL from the efs partition using Qspt, edit, and then reloaded. Show are you really getting a 5g band on your phone??????

I've been trying forever to get this to work with my ATT with stock FW and when crossflashed to EA, and you're right, I think it just doesn't, regardless of fw version installed. I've pulled the EA EFS policy files as well as the ATT ones, modified them, reuploaded and 5G just will not turn on. I've persisted so long because this method worked fine on my V50, however that one is a V500N (korean variant) whereas this is a V600AM (US/ATT variant), so I think that may have something to do with it. Have tried adding MCC-MNC, editing the rf_band lists, all sorts of combinations. I have a feeling that when the sim is inserted the phone doesn't even look at the modified xml files in the EFS partition and just generates it's own with the american models, but this is just speculation.
The other thing I noticed is that when I edit my ftm file to regain my serial number and remove the NT code error, the outer screen on the dual screen attachment works again, but then I lose 4G altogether and revert to 3G without data.
On my V50 all I had to do was add '5G' to some band lists and it worked, however, that unit is not crossflashed and still has stock korean firmware.

Well I can tell you that there's a running discussion on a lot of the points you just made not the least of which is whether or not the modem is being provisioned at activation and if so what exactly and how much.
I have 2 lmv600am which I got off Ebay. Both had been crossed to EA fw when I got them. Since I'm on Google Fi, I went to the AT&T unlocking site and Sim unlocked. I then put my G-Fi sim into 1 of my v60 and sure enough I get a 5G moniker on my taskbar. Now during this time period Tmob is changing their policies on LG phones, mainly since LG is no longer in business. For example, lmv450 no longer actives on Tmob nor any of it's mvno's and I believe the same is happening for all Sprint phones plus all LG non-tmob phones. They're checking by imei.
So it didn't take long and bam, I wasn't even getting a 5g moniker. I call G-Fi and asked, WTF. I was told that G-Fi is now only allowing Google and Samsung phones to activate with 5G services, only 4g for V600am. Once again imei strikes. BTW you can page thru modem protocols here; *#546368#*600#>field test>modem settings>engineering mode to see if you even have the 5g protocol loaded. I use to but now I only have 2g, 3g, hspa and lte.
The only reason I'm bringing all this up is because Carrier Policies are changing with LG phones so It's worth a tech support call/chat with your carrier to see what's what on their side.
The next step would be to use a serious network app to verify what really going on. I think in your area the G-Mon app is being used a lot. I use Netmonster in the US. I saw a screen shot from a guy in Poland, I believe, that thought he was getting 5g only to find out that it was really lte+ 3xCA. He was getting 727.3 Mbps on the DL which is absolutely screaming. That’s faster than 99.9 % of the phones in the US.

Forgot to mention that I noticed that after a fresh flash, the xml files present in the EFS are different before and after inserting my sim.
Interesting but also disappointing to hear about the IMEI checking :/
I've been through hidden menu settings, and depending on which firmware I have installed I can see different bands and modem protocols available/activated, but can still never turn 5G on with my american V60's.
I had so much hope for this handset since firehose was made available!
Which reminds me, I even bootloader unlocked and rooted my crossflashed at&t unit. Successfully install Magisk etc, but couldn't enable r/w on system partition, even after generating and flashing a modified super partition. Something else going on here.
YOU need to check out the v60 group over on Discord.

How do you change partition sizes?
5g network selection is not available on my nord 2. Am only able to select 4g. My network (Ooredoo Qatar) has n78 5g but am unable to connect to it. Can anyone help me modify the radio to enable it. I have already checked with 5g switch and similar apps, it doesn't work. my phone is on stock and not rooted.
You must also have a SIM card that supports 5G
He received a new SIM from the operator.
Then a 5G option appeared in the setup menu.
What is this?
This is a guide on how to enable all LTE and 5G bands on the US or Canadian S23 series phones by going through the service menu. This guide is a copy of my S22U guide, which is mostly based on this S20U guide by mellojosh, but has been adapted for the S23U phone with more information added.
Who needs this?
Different countries and carriers use different 5G frequency bands, so the phone's software limits 5G bands to your model's country and carrier even though the phone hardware supports more bands. Here are some cases when unlocking all 5G bands could be useful:
You live outside the US/Canada but bought a US/Canadian model and want to use 5G in your country that uses different 5G bands than US/Canadian carriers.
You live in the US/Canada but are travelling to a different country and want to use their 5G service which uses different 5G bands than US/Canada.
You live in the US/Canada but think your carrier is limiting your 5G service for some reason and think that you can optimize it better.
Which bands can be enabled this way?
All bands the phone supports in hardware can be enabled through the service menu. For the US S23 Ultra, that includes all Sub-6 bands like n78, and mmWave bands, as well as 5G SA bands, as shown in this screenshot below. For the Canadian S23 Ultra, this method will unlock all the same bands as the US model except mmWave (might be a hardware or firmware limitation).

}
Which phones does this method support?
This method has been confirmed to work on:
Samsung S23 Ultra (S918U, S918U1, S918W).
Samsung S22 Ultra (S908U, S908U1, S908W).
Galaxy Z Fold 4 and Z Flip 4. Thanks @Abaddon and @otteporihs.
This method works on both Android 12 (One UI 4.1) or Android 13 (One UI 5.0, 5.1).
This method requires your device be on the US firmware (XAA or other US CSC), so as long as you can Odin flash XAA firmware on your device (such as Canadian variant), you should be able to do this.
If you get this method working on your phone that isn't in the known list, post it here and I will add it to the list above.
How To Guide
You will need a Windows computer (or VM) and the Samsung USB Driver installed to do the following steps. Install the USB driver from here before proceeding if you do not have it installed.
A. Flash US Firmware
First, your device must be on US firmware (XAA or other CSC). You can skip this step and go to B if your device is already on US firmware.
If you're not on a US firmware because you have another Snapdragon variant (like Canadian), follow the steps below to flash XAA firmware. Note this will WIPE and FACTORY RESET your device. ALL DATA WILL BE LOST. So backup if you need to.
Download Odin 3.14.4 or latest version.
Download US XAA U1 firmware for your device from SamMobile.com or SamFw.com. For example, for the S23 Ultra, download the XAA firmware for S918U1. Extract the contents of the firmware to somewhere on your computer. You should have 5 files (BL, AP, CP, CSC, HOME_CSC). We won't use HOME_CSC.
Restart your phone and go into download mode. On the S23 Ultra, hold all three power and up + down volume at the same time until the phone starts, then press the up volume key to get into download mode.
Open Odin and connect your phone to your computer with a USB. Odin should say your phone was added.
Click each of the BL, AP, CP, CSC buttons and select the corresponding files from the firmware zip you extracted. For CSC, use the file that starts with CSC and not HOME_CSC (we won't be using HOME_CSC). Do not load anything into USERDATA.
Click start and let it flash the firmware (see the picture below). If it flashed correctly, your phone will be on XAA firmware after it restarts and you will have to set it up again from scratch.
Set up your phone and verify it is on XAA firmware by going to Settings -> About Phone -> Software information -> check that it says XAA/XAA,XAA/OOO under "Software provider software version". OOO here will be your phone's original CSC like XAC which you cannot change and do not need to.
B. Unlock Service Menu Secret Codes
The next step is we need to unlock access to the service menu. Usually this is locked by default, but it might already be unlocked for you.
First check if you can access the service menu by trying each of these ways:
Open dialer and enter *#27663368378# to try to get directly into the service mode main menu. The menu should open after you press the last # character, you shouldn't have to press call.
Open dialer and enter *#73# to get into RF Test mode. Press Band Selection. Press three dots on top right -> Back. Repeat three dots -> back three more times until you get to the service mode main menu.
If either of the above ways works for you to get to the service mode main menu, then you can skip the below steps to unlock the menu and go directly to instructions C.
If you cannot access the menu with the above codes, then follow these instructions to unlock the secret codes.
Enable USB Debugging in Developer menu.
Download SamFW FRP tool 4.0 or latest version from here.
Open SamFW FRP tool and connect your phone to the computer with a USB.
Using SamFW FRP tool, go to MTP tab and click on "Enable Secret Code for Verizon". See the picture below. Note it works on any US CSC even though it says "for Verizon".
If in the program output you see it's getting stuck on "Waiting for DIAG", then dial *#0808# on your phone to open USB settings and select "DM + MODEM + ADB" then press OK. The program should then complete the step and then get stuck on "Disabling DIAG". When it does, using the *#0808# menu again, select "MTP + ADB" this time and press OK. Now the program should complete the step and say that secret codes was unlocked.
Now you should be able to use *#73# for RF test, or *#27663368378#* to go directly to service menu. Test it to make sure at least one of the codes works and the service menu is opening.
C. METHOD 1: Use the Service Menu to Unlock All Bands
Enter the service menu using either way.
Open dialer and enter *#27663368378# to get directly into the service mode main menu.
Open dialer and enter *#73# to get into RF Test mode. Press Band Selection. Press three dots on top right -> Back. Repeat three dots -> back three more times until you get to the service mode main menu.
Use the service mode to set the following options. Note you can go back between screens with three dots -> back for quicker navigation, but I am just starting each option below from the main menu so it's easy to read.
Enable all LTE and 5G bands.
Service Mode Main Menu -> UE SETTING & INFO -> SETTING -> SYSTEM -> Next page 4 times -> SET LTE BAND CONFIG -> SET DEFAULT LTE BAND.
Service Mode Main Menu -> UE SETTING & INFO -> SETTING -> PROTOCOL -> NR5G -> PRUNE STATUS -> REMOVE NR5G PRUNE.
Service Mode Main Menu -> UE SETTING & INFO -> SETTING -> PROTOCOL -> GCF -> REMOVE ONLY NR WHITELIST.
Optional if you need to enable mmWave bands on US model: Service Mode Main Menu -> UE SETTING & INFO -> SETTING -> PROTOCOL -> NR5G -> Sub6/mmWave -> ALL ENABLE.
Optional if you have issues going from LTE to LTE+ (carrier aggregation not working properly): Service Mode Main Menu -> UE SETTING & INFO -> SETTING -> PROTOCOL -> AS -> Next Page -> DISABLE CA COMBO CHECK -> DISABLE ON.
Enable 5G NR features (DSS & CDRX) if needed. These options might already be enabled for you by default.
Service Mode Main Menu -> UE SETTING & INFO -> SETTING -> PROTOCOL -> AS -> Next Page -> NR CDRX CONTROL -> NR CDRX ENABLE. NR CDRX is 5G power saving mode.
Service Mode Main Menu -> UE SETTING & INFO -> SETTING -> PROTOCOL -> AS -> Next Page 2 times -> NR DSS CONTROL -> NR DSS ENABLE. NR DSS is 5G Dynamic Spectrum Sharing.
Enable 5G SA if you're lucky enough to have a carrier with standalone 5G networks. This option might be enabled by default already.
Service Mode Main Menu -> UE SETTING & INFO -> SETTING -> PROTOCOL -> NR5G -> SA/NSA Mode Control -> SA/NSA ENABLE.
Service Mode Main Menu -> UE SETTING & INFO -> SETTING -> PROTOCOL -> NR5G -> SA/NSA Mode Control -> Remove SA permit list.
Service Mode Main Menu -> UE SETTING & INFO -> SETTING -> PROTOCOL -> NR5G -> NRDC -> NRDC ENABLE. NRDC is for dual connectivity with Sub6 + mmWave bands in parallel. Only applies to 5G SA networks and only if your carrier uses it.
Restart your phone, then dial *#73# to get into RF Test Mode. Click Band Selection -> Sim 1 or Sim 2 (whichever you use). On this screen if you scroll down, you'll see a list of enabled NR5G bands. Make sure all bands are enabled. See my picture below.
NOTE: Band selection won't be reset with a reboot, but might be reset after a CSC update (or a software update that includes a CSC update). You will have to re-do the service menu settings every update or re-flash of a CSC.
NOTE: If you use an eSIM or a dual-SIM phone with a 2nd SIM, you need to change the NR5G stack before changing the NR5G related options above. Change the NR5G stack to Stack 2 with the following setting first.
Service Mode Main Menu -> UE SETTING & INFO -> SETTING -> PROTOCOL -> NR5G -> Stack Selection -> Select STACK 2.
OPTIONAL: Now that all bands are enabled and usable, you can use the Band Selection menu under *#73# to selectively disable certain bands if you need to. This is not covered here but that menu is self-explanatory.
If this method isn't working, try METHOD 2 below. You do not need to try METHOD 2 if this method ended up working for you.
D. METHOD 2: Unlock all bands via Protocol Simulation menu.
If METHOD 1 above didn't work or not all bands were unlocked, you can try to unlock all bands by simulating a change in your CSC to GCF (Global Certification Forum). This won't actually change your CSC to GCF, but will change the options in the service menu as if you were on GCF CSC, which should give you access to all SA and NSA bands. Credits to @wr3cckl3ss1 for figuring out this method.
To do this method, first enter the service mode main menu using either of the following ways.
Open dialer and enter *#27663368378# to get directly into the service mode main menu.
Open dialer and enter *#73# to get into RF Test mode. Press Band Selection. Press three dots on top right -> Back. Repeat three dots -> back three more times until you get to the service mode main menu.
Using the service menu, change the following options
Go to: Service Mode Main Menu -> PROTOCOL STATE -> PROTOCOL SIMULATION -> IMEI PRE CFG SIMULATION.
In this menu, click [1] AP, then click GCF (last option). Then click [2] NET1 and change it to GCF as well. Do the same for [3] NET2. All GCF.
Press [4] Write. Then restart phone.
Check if all SA bands were unlocked. If not, repeat the band unlocking instructions from METHOD 1 above and then restart the phone and check again.
Enjoy your unlocked LTE and 5G bands!
I have personally tested this on a Canadian S23 Ultra (S918W) on US XAA firmware to enable all bands. I reflashed Canadian firmware after I unlocked the service menu and the service menu stayed accessible even on Canadian firmware. So the trick is to always start out on US firmware and unlock the menu there first.

If anyone gets this working on a US S23 Ultra, please post the full unlocked band list as in the first screenshot (which is an older screenshot from my US S22U). My Canadian S23 Ultra doesn't have mmWave bands, so I want a screenshot with mmWave bands enabled with the US S23 Ultra model. Thanks!
Can you just flash U firmware using Home CSC to keep the data?
Which US CSC enables spam protection and/or visual voicemail on a Canadian SIM card?
Thanks for this. I was curious if it was possible to enable all the things on my U1 I'm picking up tomorrow. Unfortunately it seems to confirm no n70 but hopefully Samsung and Dish can come to an agreement to add it but even if they don't, I'm just happy to have lower band n77 since that's all the midband AT&T can use here til 2024 (Pixel 7 Pro doesn't support it, a key reason for my upgrading other than the screen keeps failing lol)

In my experience , if you're switching from W to U/U1, you cannot use HOME_CSC. It will end up saying there's a boot up error and you'll need to factory reset.
Once you unlock the service menu with US firmware, you can then flash Canadian W firmware again and the service menu will still stay unlocked (with *#73# method), so you can still unlock bands on W firmware. You don't need to stay on US firmware.
I haven't been able to find any US CSC that works with Visual Voicemail in Canada. But for spam protection, any US CSC other than XAA should work (you'll need to change it through SamFW and disable cidmanager with ADBAppControl so it doesn't revert back to XAA).

Are you in the US with an AT&T SIM and going to use U1 phone? The phone should already have the bands for your carrier. I don't see why you would have to unlock anything?
i have SM-G996B (S21+ Exynos) and i changed my CSC (INU) to DBT for getting oneui5.1 update. After CSC change i got FOTA update but 5G not working in DBT CSC, so i switch back to INU but nothing change. I cant flash INU fw because Samsung not release oneui5.1 update for Indian user. Final word is My 5G not working after csc change.....can anyone help me

I am in the US but I'm using a T-Mobile MVNO (Tello) for calls and texts and Dish Network's postpaid service, Boost Infinite, for my data. Boost Infinite is currently using AT&T exclusively but they'll be sending us new SIM cards some time this quarter or next that change us to their network as the primary, AT&T as the secondary, and T-Mobile as the third priority with automatic switching between them a la Google Fi. Dish uses n29, n48, n66, n70, n71, n262, and if they buy it from T-Mobile, n26. This phone supports everything but n70. I'm hoping that Samsung will add it later as the modem supports it (in fact the iPhone 14 Pro/Max with the year older X65 supports n70 and so do a few other non-flagships from last year like the Moto G Stylus 5G so it doesn't require a flagship modem).
I tried these steps and more from the s21 and s22 guides multiple times a few days ago. On my T-Mobile SM-918U running the out of the box T-Mobile firmware. Didn't work for me.
Edit: If in the program output you see it's getting stuck on "Waiting for DIAG", then dial *#0808# on your phone to open USB settings and select "DM + MODEM + ADB" then press OK. The program should then complete the step is where it gets stuck. Regardless of what USB Setting is selected, it still sits on Waiting for DIAG.

I recently flashed 5.0 U firmware on my 4.0 S20 with Home CSC and it didn't wipe the data. I will try and report.

It works perfectly fine for other people on S22 so there must be something you're doing wrong or a driver issue.
Make sure you have Samsung USB drivers installed, or reinstall them. If it still doesn't work, try to change your CSC to XAA or VZW then try again.
Also let's keep this thread about S23U, use the S22U guide to post your issues for S22 there.

It didn't wipe the data when you went from U to W firmware or vice versa? Well maybe S20 is different, but for S22 and up it will flash but will end up saying there's an error when booting your phone and you have to factory reset in recovery to make it work.

I have an s23 Ultra. ADB works fine because I have used that to remove the few Facebook apps and other social media trash I don't want on my device. I won't be converting to the XAA until I get the SIM lock removed. To remove the SIM lock, the device must be on the TMB U.

Try to reinstall the Samsung drivers (ADB might work because of Android drivers instead of Samsung) or try a different cable. Some people have reported a similar issue but it worked for them after reinstalling the Samsung drivers or using a different cable. At the least you should be able to get past Waiting for DIAG.
can anyone with a German or European S23 say if this is useful for us?
i have the S918U1 stock firmware i am new to samsung, i believe this is the US version already correct? if so the *# codes do not work and i am unable to find the correct firmware for this phone from sammobile the U1 shows no match when searched for on sammobile.

Yeah it seems like a lot of the codes are disabled on the U1. I can't even read my CSC using the *#1234# code that I found when searching the web, just doesn't do anything. *#0011# still works and that's primarily what I would be using anyway so that's good at least but I have to find a new way to read the CSC code.

I would like to know this too. Even though 5G isn't widespread in EU (no mmWave etc.), I'd like to enable it if the phone supports this but is limited/unabled for no reason.

Did you follow the guide to unlock the codes with SamFW FRP Tool? You have to do that for the codes to work first...

No unfortunately this method is for US/Canadian phones only.
