I'm interested in flashing the VZW user data. Where did you find the info you needed?

Actually, I haven't quite. None of the Verizon ROMs I'm downloading from updato have the userdata file

I heard I can call Verizon and get a tech to enable the vzw features like WiFi calling... I may try to do that tomorrow.

No Wi-Fi calling, no Video Calling, no Visual Voicemail. Sorry.

It's interesting that you posed this. I have been messing around with my phone trying to get a TMO firmware on my Verizon variant. Every time I would flash the firmware, I would get an overlay of Verizon and TMO apps. You can check my thread for details, but this is the firmware that I was working with: N950USQU1AQI5 - SM-N950U TMB USA (T-Mobile)

Does the ROM you're flashing include USERDATA file that you stick in the UMS slot in Odin?
Went and read your thread, what a friggin' disaster. I flashed Verizon ROM yesterday. The software version was showing as VZW/VZW/XAA. Verizon never recognized my device as a Verizon one, so still no luck with Wi-Fi calling, Video calling or Voice Mail. Then I tried to bring back Samsung Cloud by linking to the activity via QuickShortcutMaker. Seems to work for a lot of people, but for me it was just force closing. Got pissy and flashed back to XAA firmware. Restored everything from Samsung Cloud and am pretty content again. Screw Verizon is all I can say.

Yup, I've tried multiple different firmware versions that all had the USERDATA file flashed into UMS. I am trying to do a carrier change with the factory binary firmware that BlueFox721 found, but so far, it isn't working. I am sure that someone will figure something out soon though....maybe....hopefully....? I am thinking about flashing to XAA firmware and leaving it alone as well.

I'm not 100% sure about that. I know without the Verizon USERDATA we will not get Verizon Visual Voicemail. But "HD Calling" (VoLTE) is an option on the phone. That's one down I guess. Verizon locks out video calling when you activate an unlocked phone (at least on my account they did), so I know I'm not getting that.
WiFi calling is an interesting one though. It's the only one I REALLY REALLY want. I spoke with a tech who hopped into my phone via diagnostics through the My Verizon app. She said "Advanced Calling" is enabled on my phone, and confirmed VoLTE. She said VoWiFi is there but it's like it's greyed out, she couldn't enable it She said that Verizon isn't actively "blocking" it. I'm seriously hoping it's in a hidden shortcut somewhere.

I have vzw firmware with userdata on my unbranded note 8. I got it from updato. It was uploaded on Sept. 15th. I can confirm that wifi calling and visual voicemail work.

Can you provide the link to the ROM on updato? Also, did you do anything special besides flashing all files via modified Odin? Which CSC did you use? Thanks!

I flashed the u not u1(which is my model #) via Odin found at:
https://www.sammobile.com/firmwares/SM-N950U/VZW/download/N950USQU1AQI5/188972/
Everything works except video calling because Verizon blocks it on their system if you're not using a Verizon IMEI#. There is a workaround though. If you put your sim card into a Verizon branded phone, boot it, then pull the sim and put it in your unlocked note 8, video calling works until you reboot and their system catches a non Verizon IMEI number hitting their network. Then it's automatically blocked. I started using Google Duo instead and I'm happy. Wi-Fi calling, VoLTE, and Visual Voicemail are all working great.

Ohhhh, almost forgot, use the prince comsy Odin to flash the user file.

I may try it again at some point. For now I have everything set up exactly as I want and I like Samsung settings menu much better than Verizon's. I like the ability to use Samsung cloud too. Voice mail is about the only thing that I miss but Google Voice is working great and even transcribes voice mails for free (as opposed to $2.99/mo Verizon charges for "Premium" Voice Mail). I've never used wi-fi calling or video calling. There are so many apps like Duo, Viber, WhatsApp, Skype that can do the same thing, it's really a non-issue.

These are the links I used to flash my unlocked n8 to give me all the features needed to work with Verizon. I'm using Google voice for my voicemail and video calling isn't an option.

Flash the BL in BL, AP in AP, CP in CP, CSC in CSC(not HOME_CSC), and the USERDATA in the UMS. To enable UMS ensure your using the Prince Comsy Odin, right click the Odin3.ini file and edit it, change UMS/PATCH=0 TO UMS/PATCH=1 and save. Flash all together and everything works except video calling because Verizon blocks it on their system if you're not using a Verizon IMEI#. There is a workaround though.

You can also call to have your imei added to their list...if one tech does not know how...call another until one will...others have had success and it adds all features available...

Purchased an N950U1 ("unlocked") from Samsung under the Note7 injured customers plan and put it on Verizon.
I need wifi calling due to weak signal at home but I also need the flexibility of an unlocked phone to use on international travels.
Have not yet modified my phone in any way.
Talked to a Verizon rep today.
He refused to admit that there is a way to change the IMEI in the database. Claimed it was an administrative/financial/controlling/some other crap that makes it not possible. He was able to provision voLTE (HD Calling) but no video calling and no wifi calling (important for me due to weak cell signal at home).
When Samsung builds the phones it publishes the IMEI listing what exactly is in the phone. Verizon looks at that list and if it's not originally a Verizon Firmware from Samsung, they won't provision it for certain services. (Apparently unless you reach someone who knows how to go around it, haven't tried multiple calls yet.)
This is kind of a new situation since about the Samsung S8; phones are (finally) all hardware identical (in a specific region, anyway) but only differ in firmware.
The next improvement is that the carriers are slowly realizing that blaotware is bad (Too slowly but at least progress is being made.) - even going so far as to allow some of it to be uninstalled - and more recent versions of Android offer more control over stuff so bloatware is not the issue it once was.
Differences between phones:
- Unlocked has: Samsung cloud, Samsung interface
- Locked has: Verizon bloatware, wifi calling, video calling, visual voice mail
(Did I miss anything?)
So far I see the options are this:
- Leave phone as is, accept fewer calling options in favor of less bloat and other improvements
- Install Verizon firmware and hope to find someone who will "fix" the provisioning
- Install Verizon firmware and activate it by switching from a "real" Verizon phone to this one without a reboot (how does that get the wifi calling to appear in the menu?)
- Return the phone and get a Verizon version.
Not sure yet what I'll do but leaning towards the Firmware/"Fix" version.
To complicate things, wife is on AT&T. That has even worse reception at home and she's there much more often.

If you need Verizon's wife calling and video calling on, you need to flash Verizon firmware in full.

Wifi calling problem

Both my dad and I picked up the Note 8 on launch day. I had zero issue enabling wifi calling out of the box, and in fact it seems to be working quite well for me. He's not had the same success. At first it said it would have to disable Google Voice. We uninstalled the app, and had Sprint de-integrate his number with Google Voice, so that the carrier stock voicemail could be configured. That didn't work initially either, and he spent some time at the store having their tech fix it. I wasn't there, so I'm not sure what they did, but eventually they got the voicemail working. So then he came around asking me to set up wifi calling. I attempted to, only this time the setup prompt insisted that it be allowed to disable Voicemail first. But since that's a system app, I'm not sure how that can be done. And given his problems with voicemail to date, I'm reticent to let it try and disable his voicemail again.
Anybody else run into this problem? Is there some sort of fix that doesn't involve another visit to Sprint?

If you are having issues with things not working on Sprint, I first had to factory reset...all was well afterwards...make sure you have a brand new SIM for the Note 8...is it a Sprint or Unlocked device (SM-N950U or SM-950U1)

Same here. I bought mine directly from Samsung and just found out that the option to select WiFi calling is missing! I rely on this at home because we live in a valley with poor cell phone reception (I have to step to a front window to make/receive calls without WiFi calling).

You can flash Verizon firmware if you want WiFi calling on Verizon...but some users have successfully had it added to the unlocked version by calling Verizon and adding their imei to Verizon database....search the threads if you need...

Thanks. I tried searching the threads but didn't find much. Maybe I need to change how I'm searching. If I do need to "flash the Verizon firmware," where can I find instructions and will it add bloat or reduce the functionality in any way (I wanted non-Verizon because of the way Verizon changed features on my Note 5)? Will flashing the firmware interfere with the Samsung support?

I called Samsung tech support and they confirmed that this feature is not in the based version of Android but the ones distributed by the carriers. The tech suggested calling Verizon and asking them to install the firmware. Anyone know if (assuming they agree) this will be the full package, including all the bloatware, and if this will remove any features from the phone? Would the "upgrade" wipe out the phone so that I have to set everything up again?
When I bought my Note 5 from Verizon two years ago I was upset to find that they had removed the PDF signing capability that was a big feature of the Note 5. I'd really hate to lose any features on my new Note 8, after all that's why I bought directly from Samsung.

In order for you to remain on unlocked firmware to avoid bloat and keep Samsung goodies you must call Verizon to have the imei # to their whitelist and reprovisioned...I did this for Sprint to enable VoLTE when available...others with Verizon have done the same...call Verizon cs and tell them you bought from Samsung and need to have your imei # whitelisted and reprovisioned to improve network connection...if one rep will not do it, call another...do not mention that it is unlocked version...just state that you got from Samsung on a Note 7 deal...afterwards, all Verizon features will work on unlocked except vvm...Google voice is better anyways

I'm slightly puzzled by your vvm comment: will all Verizon voicemail be non-functional or only Visual Voicemail? I have Google Voice set up to provide a second number on my phone. How do I use it to set up voice mail on my phone with my Verizon number?

VVM is only on carrier Firmware...it is baked in...some have gotten it to work on unlocked but I do not know how...regular voicemail works fine...especially with Google voice...to set it up you forward to Google voice...for Sprint it is dialing *73mygooglevoicenumber...I do not know the forward shortcut for verizon but it used to be *71yourgooglevoicenumber...
Your Google voice number is shown in the settings of Google voice.

First, I found the Google Voice shortcut for Verizon is what you thought: *71yourgooglevoicenumber
Now for my bad news. I spent nearly an hour on the phone with Verizon tech support. After being bounced around a little, I spoke with a woman who kept contacting their "Network Team" for more details, and who tried to be very helpful, but in the end I am no further ahead. In the end, they said that adding my phone to the Whitelist was "Out of Scope" because the phone was already unlocked and functioning on Verizon. She said that all she could suggest was to contact Samsung, and that Verizon tech support would be happy to have a three-way conference call with Samsung tech support (they would call) to see what could be done, and that she'd put a note in my account about this issue.
Now, if I call back and try to speak to anyone else they will see this note that that will be it. So, I'm back to not being able to make phone calls at home.

For now, I have a partial solution for the poor phone connection at home: years ago, after we had complained a lot about a poor signal at home, Verizon gave us a free "Network extender," which acts as a mini tower in our house (connected through the house Internet). It is only 3G, so I disconnected it when we had WiFi calling on our phones. Now, I'll reconnect it. The only problem is that is won't connect to a phone with VoLTE calling enabled, so I have to remember to turn off VoLTE calling when I get home, and turn it back on when I leave so that I can keep my Internet access on a phone call.

SM-N950U1 Flash to Verizon software

Recently purchased an unlocked Note 8 Model SMN950UIZKAX from Best Buy to use on Verizon and was wanting to Flash Verizon software to it to get the advanced calling features and other Verizon stuff that is missing. My question is if I flash the latest firmware found on the Sam Mobile site for the SM-N950U1 for Verizon....I think from 9/15, would this enable the options? Is it possible to flash back to the Unlocked software once the Verizon software has been flashed if I decided to? Is there a better option other than flashing? Please be gentle because I have been out of the game for a while and want to make sure I am doing everything right.

-HD voice (VoLTE) can be turned on by calling verizon. *611. (For us U1 people)
-After 2 hours of talking to VZW, and lots of lots of reading here on the great XDA- The only way I have found that implies Video Calling will work on the U1 for VZW is to flash the carrier package above. Effectively turning your "unlocked" into a carrier branded phone.
-Per VZW, Wifi Calling simply will not work. (cant confirm or deny).
Personally hoping we find a way to flash the video calling / visual voicemail / wifi calling modules only without having to flash the entire firmware.
I flashed the sm-n950u firmware and all functions fully work with the exception of video calling due to a non Verizon IMEI.

To enable UMS ensure your using the Prince Comsy Odin, right click the Odin3.ini file and edit it, change UMS/PATCH=0 TO UMS/PATCH=1 and save. Flash all together and everything works except video calling because Verizon blocks it on their system if you're not using a Verizon IMEI#. There is a workaround though. If you put your sim card into a Verizon branded phone, boot it, then pull the sim and put it in your unlocked note 8, video calling works until you reboot and their system catches a non Verizon IMEI number hitting their network. Then it's automatically blocked. I started using Google Duo instead and I'm happy. Wi-Fi calling, VoLTE, and Visual Voicemail are all working great.

You can just flash the USERDATA in UMS, but you won't have WiFi calling.

Is it possible to flash the Verizon on a Unlocked to get the Visual Voicemail then flash back to Unlocked or you have to remain Verizon to keep Visual Voicemail?

Visual voicemail requires USERDATA or complete flash...after root, we can edit buildprop and get vvm working on unlocked. There is a way to edit buildprop via adb but you must know the vvm settings to add...i am looking into doing it for my Sprint but am debating because I am liking Google voice better
for Verizon on unlocked...some have called to have WiFi calling and VoLTE added to their imei #, or the imei # added to their database so that the device can receive an update enabling those features...Sprint has features enabled for any imei as long as the SIM is one on their records...problem is getting a Verizon rep that will know what to do with the imei...good luck

What specifically did you flash for VVM?
Follow the instructions in post #8 and you will have vvm. I had to call after and they had to activate it under my new IMEI but overall not as arduous as trying to get them to add my IMEI to their database for Video Calling (I still haven't found a rep to do it).

What phone did you have prior to the Note 8? Video Calling & VoLTE is super easy to get working
I had the note 4 for a while, seems Verizon has blocks that can all be removed by admin with the exception of video calling. Wheather I log in and try to remove the block or an admin, it automatically re-enables the lock due to the IMEI not being a Verizon phone. I found a trick to get the lock off but when I reboot my note 8 their system picks up a non Verizon IMEI and defaults back to locked. I have a request to have my IMEI added, but it's been a week already and it still kicks back on. Wish I knew a Verizon admin with the juice, if they haven't added it in a few days then I'll try again but if they won't add it then it's Duos, hangouts, or FB messenger for Video Calling my U1. Wish I could spoof my IMEI, maybe I'll look that up later today, but it's probably chip based.

I've been using my U1 with Video Calling since 9/5 without issues, features stay on the account unless you remove them.
Do you still have the Note 4? If I recall that was the first VZW device with WiFi Calling/VoLTE, if you enable the features on the account they stay on. I've been using unlocked devices since ~2012 & they have always worked without issues accept WiFi Calling which requires VZW firmware
Not working like that for me. Every time I reboot automatically blocks video calling.
So, I made the choice: I took my unlocked back and swapped for the VZW branded one.
I was under the impression "unlocked" was the bootloader when I bought the U1, but yea, it wasn't lol. I was tired of trying to get everything to work on the U1 and some of big reds features are really neat. A few hundred MB space wasted on bloat is no big deal to me, and I have never left the USA in my life, so VZW is fine.. With things like BK disabler, it really makes dealing with carrier bloat ALOT better then on the say S4 where you couldn't turn it off (stock, luckily there was awesome root/roms). I literally turn everything off from VZW I dont want with BK, deny their permissions and clear data, and they can just rot hidden away.
I have noticed The U1 comes with free ultra caller ID spam thing, the VZW doesn't have this, that I can find. Talking to VZW now to figure out why I don't have this feature on my new phone for free when the unlocked has it. EDIT: Dunno if I would recommend switching anymore, that caller ID is very nice and used WAY more then wifi calling for me. Wifi calling ONLY works when the phone has no mobile signal period. Which kinda defeats the purpose I wanted it for was to save minutes. (Thought it would make calls over WifI when connected like data, but that isnt the case) The VZW version is also missing the built in clean master, which I also enjoyed. Its like you trade 3 samsung features for 3 VZW, cant have them all and Im getting upset with big red honestly.
If and when we get root, it wont matter which phone we have from what I read, because it will come from an ENG firmware which can be flashed on anything.
So the only Verizon app I would like working on my unlocked u1 note 8 is NFL mobile. I literally don't use any of the other ones and personally like how clean my note 8 was out of the box. Is there any short fix to get that working or would I have to go through the whole way of flashing the vzw firmware a few steps back? I don't mind some, but I just got the phone how I want it lol so I don't want to do it if I don't have to.

(Firmware Inside)Unlocked Samsung Note 9 - Finally Verizon Firmware With Wifi-Calling

Hi All,
I have been trying to follow all of these threads and waiting to get my hands on some VZW firmware since I am on verizon. I was rocking the Unlocked firmware but with only VOLTE , which is ok but I wanted to have backup for WIFI-Calling. I noticed in the other thread ( https://forum.xda-developers.com/ga...ock-odin-files-firmware-t3833205/post77449285) a user said to use Sam Mobile to download the firmware which Took about 5 hours. I figured the APP could maybe pull it if I typed in the right Model and Region. I tried using some different ones and the one that worked was the model : SM-N960U1 with "VZW" as the region. I have attached the screen shot and also uploaded to google drive for people to easily download.. Enjoy !!! The exciting thing is I used Odin with the said files on top of running the unlocked firmware and used the Home CSC and my data was kept safe. Basically everything was the same and it included the crappy Verizon apps but now I have wifi-calling .. sorry just a little excited..
The full Firmware name is this : N960U1UEU1ARH2/N960U1OYM1ARH2/N960U1UEU1ARH2/N960U1UEU1ARH2

By flashing the VZW firmware you also lose the samsung cloud and also the places and Caller ID/Spam feature. Maybe more but that is as much as I can tell.
For me that's not a big deal

One thing I just noticed is that, using android messages was I thought working 100 % but then I had people calling me saying they were texting me and I wasn't getting them.. They would get the SMS I sent but I would not be able to recieve. I switched to the Samsung Native app and bam my messages were there. I don't know if thats because I did not wipe first before doing ODIN or not ..

This is a common issues with newer Samsung phones. Their implementation of Advanced Messaging is half-assed and unfortunately you almost always have to stick with their SMS app to not have issues. Luckily the app has been updated a lot since the S7 days and is no longer a steaming pile of garbage.

Are you using Verizon as your wireless carrier? How did you turn it on?
My note 9 (unlocked XAA) doesn't have any options to turn on Wifi calling when my Verizon SIM is inserted. But Wi-Fi Calling turns on with a notification in the shade, and I can toggle via phone>menu>setting>wifi calling, when my T-Mobile SIM is in the phone.
@KidJoe
I did this on My device, Unlocked to VZW. It worked.
Wifi calling is located in Settings>Connections>Advanced Calling. Make sure you have a proper cel signal when you activate it.
Notes:
- As OP mentioned, Use the Home CS file and all of your existing settings, apps, etc won't get wiped.
- I was surprised that there were only like 6-7 crapps that came from Verizon. Mostly Yahoo mail and a couple games. The Verizon "Security & Privacy" and Cloud apps cannot be removed. I kept the voicemail and caller ID apps.
Otherwise, it seems like a pretty quick and easy fix.

that is after flashing the rom in the OP though, right? (I mean that is how it is on my VZW branded Note8, GS9 and Gs8. Yes I have many phones.. don't ask)
I was reading NICEGYPT's post as if it was done on the unlocked without flashing which is why I asked.
Question though. Since I did flash my VZW branded GS8 with the unlocked/unbranded to get the Oreo beta, and back .. for that phone there were more steps than just flashing the rom... Requiring a factory binary and other home csc file, etc. That doesn't appear to be needed non the note 9, is that correctly?

Is there a way to get Samsung caller id/spam feature?
thank you for posting this! Will definitely try tonight on my unlocked Note 9 from BB, I did not realize that ordering the unlocked would disable wifi-calling with verizon.
Question: Will flashing the verizon firmware over my unlocked note 9 enable sending SMS via Wifi using the Android Messages app?
I'll be going on travel overseas, Wifi-calling is definitely nessasary for me, and sending SMS via Wifi using the stock android texting app would be icing on the cake
I also have US Unlocked from BB but on Verizon network.
Just to make sure that flashing this Firmware does not require OEM Unlock and won't disable Knox ?
hello
you don't need to reflash the firmware N960U and N960U1 are multi CSC so :
save all your data
- Power off the device
- remove the sim tray.
- Go to recovery , HOLD home ( or bixby button ) + Volume up together , and power up
- In recovery , chose factory reset .. This will give a warning and then reset everything
- Choose power off , in the recovery and insert sim tray .. you should do this before booting up as your CSC will be configured when you will start
- Power on the phone , wait and . then chose restart to system now when asked
- wait and after reboot , your CSC have change according the sim tray
some peoples do this without remouving the sim tray

Can I install stock AT&T ROM on an unlocked S10 from Samsung

I just got my new unlocked S10 all set up dialed in. Model SMG973U1ZBAX.
I put in my AT&T SIM card in and went to turn on Wifi calling and couldn't find it. I've since learned that if you have an unlocked phone, you can USE the AT&T network, but you can't get Wifi calling (which is a must for me), Visual Voicemail or HD Voice.
Instead of flat out returning it, can I just flash the AT&T ROM and it would be as if it was a a stock AT&T phone?
I know I would get all the bloatware and stuff like that, But I have to have wifi calling.
Are there links yet to Stock AT&T ROM for the S10? I couldn't find any on the site.
Thanks

Yes you can there's a thread somewhere in here with specifics on how to do it. I know you have to flash thru patched Odin and make sure you also flash userdata and csc to corresponding carrier.

Root is unrelated to firmware flashing. You only need Odin and the fw package. Your computer may, or may not need the Samsung USB drivers to be recognized.
Samfirm can be used to pull updates. You might find it on sammobile or updato, haven't checked.

Sigh. Well. I can report and confirm that you can not use Wifi calling on the AT&T network with an unlocked S10.
Even though I loaded stock AT&T firmware, and was up to date, it just won't work. Gotta return the phone.
I've been dealing with their advanced tech team for over a week and they said that because the IMEI number shows it's an unlocked phone, the system keeps denying Wifi calling.
We actually got it to work at one point. It was a 3 day process with one of their techs forcing my IMEI number through their system. It worked for about an hour, then their system caught it and kicked out it's provisioning.

Galaxy S10 unlocked ATT firmware question
Hi I recently got Galaxy S10 Unlocked phone on online. At first i didnt get ATT wifi calling options appeared in my phone. Later i followed same thread that has 973U ATT firmware links, and flashed using ODIN. I can see all ATT apps and ATT wifi calling option now but i cannot enable it. When i enable it i got a message saying we cannot turn on WIFI calling on this a device and error code EDS0008. I tried to call ATT folks, but they are saying WIFI calling and HD voice is not supported on this unlocked device. Somehow they are seeing 973U1 as model number, but i had 973U as model number. I tried chaining sim to old iphone and I saw WIFI calling is working with IPHONE, but its just this phone I am seeing error. I am not sure what to do now. Did you see this issue ?
Can you give me exactly about the files you used and post steps to get att wifi calling ?
sorry for posting questions in multiple threads

Your best bet is to do an exchange for an AT&T version.
You can Flash the AT&T firmware. But there will be no way in h*** for you to actually enable the Wi-Fi calling feature since they block those IMEI numbers on their servers. YOU HAVE BEEN WARNED. YOU MIGHT NOT BE ABLE TO REVERT IT BACK TO THE OTHER FIRMWARE.

I'm away from the computer I did it on but I used the SAT1 firmware file and then manually updated all the way back up to the June update.
The updating part is/was a major PITA as it wiped the device each time. I'm hoping i'll get OTA's when they are released. Time will tell.
I'm in the Bay Area on ATT and it activated right away on the base february firmware I installed initially. Also I don't think I did any userdata stuff as I don't remember choosing it... I'll update this post tonight when I can check all the files I d/loaded on my machine at home.
Couple other things:
I can't find it right now but I followed a post that stated to make sure the SIM and SD card were removed during the flashing process. Not sure if that makes a difference.

did you ever run the unlocked firmware on ATT or did you flash to att before ever using an active sim? i had heard some speculation that once you run an unlocked phone, then it gets registered as "non att"... keep in mind this is 3rd hand info and hearsay.

I recently bought an unlocked Galaxy S10 SM-G973U on Amazon. Got new SIM card from a Verizon MVNO and activated phone. The phone downloaded Android 12, One UI version 4.0. Firmware Build number SP1A210812.016.G973USQS6HVA1. Service provide Software version SAOMC_SM-G973U_OYN_SPR_12_0007 SPR/XAA/VZW. The problem is there is no menu option to activate/switch on VoLTE which means when I'm on a call there is no internet. I've talked to the MVNO tech support multiple times and was told they couldn't see any problems on their side, or that the SM-G973U does not support VoLTE which is not true. I found on one of AT&T's sites that the SM-G973U needs a software patch to enable VoLTE. I also found a couple of USSD codes but they either didn't work or didn't get me to the right setup screen to turn on VoLTE. I even stopped by a Samsung store and they weren't any help either. They said they could re-flash a stock firmware but it would revert to being locked to a carrier which is apparently also not true based on what I've read on this forum. Anyone know how I can turn on VoLTE or know of an apk file or software patch to enable VoLTE?? Does one of the firmware versions posted online have the patch to turn on VoLTE??
I think the issue is that your phone is showing SPR/XAA/VZW. You say you're on a verizon MVNO (who, by the way?)... but your phone isn't seeing that. It's actually saying it's active for SPRint. The second one, XAA, means it's not able to detect the SIM type... and the third was that it was originally VZW, which you can't change and isn't really relevant. (That's just what the phone was "born" as).
Bottom line, your phone isn't seeing VZW or an MVNO as the active CSC nor the SIM card. In the past, the easy thing was to change the CSC to what you need, but I haven't found a way to do that actively. What's supposed to happen is that the CSC should update based on the SIM card and cell signal you're getting... but this doesn't always happen. I bought two phones - one switched with no issues, the other I could not get it to change no matter what I tried.
That said, the easiest thing is to clean flash the phone with ODIN to a VZW or your MVNO's ROM, so that (hopefully) the CSC updates automatically. You could also consider flashing a U1 (unlocked) ROM, as yours is not technically an unlocked ROM (U means it's a carrier ROM... which may be why it's not switching over?)
Again, I tried all of these on the second phone I bought, and nothing would switch it (my carrier is Total Wireless, which is a VZ MVNO, and actually shows up as Tracfone (TFN). I had to return that second phone and get another with TFN already activated, and that worked fine... so be sure you do this before you drop out of your return period.
Bottom line, you should be able to get this all working... my VOLTE/VOWIFI works fine... just a matter of getting you there.
Thanks. My carrier is Straight Talk which is now VZ. The SIM card they sent me has the wording "Verizon Compatible" written on it. I finally found a document that explains how to interpret the CSC codes and your explanation clarifies my understanding of it. Sound like I'll have to re-flash it. Since it was originally a VZW phone I'm thinking I should flash it back to VZW to see if that works before trying U1.
Dumb question as this is my first time flashing a phone. (I've flashed quite a few other things but never had to worry about CSC codes and bootloader versions, etc.) I don't see VZW firmware on samfirms or sammobile. I see Sprint, T-Mobile, and one listed as USA without carrier info but I don't see one for VZW. Can someone point me to the correct location to download SM-g973U and U1 firmware for VZW? Greatly appreciated and thanks for putting up with my lack of knowledge!
Edited: Found the files on sammobile. Will try the U1 (VZW) first. I'll keep my fingers crossed.

Success! Was able to flash U1. VoLTE is now working. The CSC now shows TFN/TFN/VZW. Much appreciated!!!
Awesome, glad to hear that fixed it easily!
And TFN... I'm a fan there, too!
Hi! I'm having a similar issue with the same model and happy to see someone was able to enable VoLTE. However, most of what you said above is a foreign language to me. Would one of you be willing to give me a crash course in what you did?
Here's my specific situation. Last week (~1/4/23) Tracfone shutdown 3G. My Samsung Galaxy S10 (SM-G973U) says my network is set to LTE/3G/2G. I've read LTE is 4G, but still can't make or receive calls/texts, but data and 911 calls still work. Their tech support is no help.
From reading online it sounds like I may need VoLTE, not just LTE. Hence finding this thread. If one of you would be willing to spare some time to walk me through what you did I'd really appreciate it. In the mean time I'll try to figure out what "flashing" mean in a context that doesn't involve showing body parts
Thank you in advance!!
I'm on Tracfone (they were bought out by Verizon, BTW) - I was on Total Wireless before, which is now Total by Verizon. You might try contacting support again, as they are now VZ, and may have more help to offer.
My S10+ is running 975U1 now, and it works for VOLTE/VOWIFI properly. You may consider getting a U1 ROM installed, and maybe even the VZW (or TFN) version if available - that may get you working.
Did VOLTE ever work for you before on this or any other carrier? What is your CSC right now?

Thanks for replying! I'm not entirely sure if VoLTE has worked previously. I bought this phone 6/2021 and have only haver had tracfone service for it. I did find in my setting that VoLTE calling is set to on so it seems like it should work. Of note, the 4Glte in my status bar has always been grayed out (I went back and looked at some old screenshots).
My current CSC is VZW/XAA/ATT.
I spoke with tracfone customer service yesterday and they had me reset my network setting and now I don't even have data and the 4Glte in my status bar that was previously gray has now completely disappeared.
Their customer service refuses to talk to me now (literally no one answers when it transfers to an agent) or they hang up on me, and no I haven't been rude, but I have told them I'm recording the call.
I bought a mint mobile package last night because I'm beyond frustrated with Tracfone. I'm worried I'll have the same problems with Mint. I'm not sure if my settings are screwed up or if it's just Tracfone. In any case things are worse now after talking to customer service yesterday.
I also notice there was no APN setting on my phone so I updated it today and restarted but no difference.
Thanks for any input!! Much appreciated. Sorry for the novel.
Ok, so based on your CSC, the phone is not seeing the SIM's carrier - it's showing XAA which means it's using the default settings, which is probably why your not getting VOLTE. The active CSC of "VZW" may be ok... depends on which carrier you're on with Tracfone. I think they're VZW only, but I'm not completely sure.
You may want to just get a new SIM card and get that activated. HOWEVER, the problem you'll likely face is that the phone was born ATT (last CSC). This means the IMEI won't match a "compatible" phone to Verizon, and they will flat out refuse to activate it (even though WE al know it will work fine). If you still want to do that, you will have to activate the new SIM on a VZ "compatible" phone, then you can swap it to the S10. Note that VZ complains about this when you talk to them... so don't tell them you're doing this... but I've done it many times and it works fine.
If your actual behind-the-scenes carrier is ATT, then you can do the activation with your phone without issue.
If none of this works for you, you can switch carriers to an ATT MVNO and you should be good to go.

OK some of that was still over my head. I'll see what happens with the Mint Sim... one f/u question now though. You said the ATT means my phone was "born" ATT. I bought my phone off backmarket and it was sold as "unlocked". Was that not true? How can I be sure in the future if I buy a used phone that's not from my carrier that it will actually be compatible?
Unlocked just means it's not locked to a carrier. That is true in your case, otherwise you wouldn't have been able to install ANY non-ATT SIM. So, you did the right thing to get an unlocked phone, and that is what you got.
The issue with compatibility is just the asshole carriers spreading lies. They do this to try to get people to buy THEIR phones, for no reason other than to make money and confuse consumers. The "born" CSC has no bearing on anything, really... neither does the carrier-specified IMEI. In your case, the XAA is good, which means it's a multi-carrier ROM, which works with all USA carriers.
Mint is a good idea - being an ATT carrier (IIRC), that should work and they should help you get it up and running even if they have to activate it. Good luck!
Awesome! Fingers crossed!! Thank you for your time and all the info❣
I'll try to remember to give an update in a few weeks for future readers

UPDATE: Switching to Mint worked like a charm! Once my number ported and I put the new SIM card in, service was instantaneous! I've had Mint for 3 weeks now and the service is so much better than with Tracfone! My calls go through nearly as soon as I hit call, the internet is faster.
I didn't need to do a thing either. No making APN settings, etc. I'm betting it has to do with what you said about my phone being born ATT. So funny because the software(?) is Verizon - shows the Verizon when I restart/power up. I still love my bastard phone
So thankful I didn't buy a different phone!!! Again thanks for all your help @schwinn8
Thanks for reporting back and letting us all know, and I'm glad it worked out well!
Yeah, the carriers pull this nonsense all the time... it's BS. The phones are all the same, only the ROM changes. If we can change ROMs (which we can) then there should be no reason to force users to specific IMEIs. But we know why they do this - follow the money. I encourage people to write to the FTC and FCC about this (I have).
