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)

It is a N950U from Sprint with carrier lock.

Coolness, factory reset is probably the best...unless it is because of a previously used SIM

I have an unlocked note 8 (US) on Verizon, and no wifi calling at all.

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?

You can flash Verizon firmware with Odin using this guide:

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

If I get them to add my imei to the whitelist and "reprovision" the phone, when they do that the option for WiFi calling will appear?
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?

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.

Extracted it from the T-mobile ROM and dropped the files into a CSC changer flashable zip for an S8, modified it so it would work on my Note 8 and flashed it.

yeah it's in my thread here https://forum.xda-developers.com/showpost.php?p=73858645&postcount=17
But I redid it last night after someone confirmed that they didn't even need the Note 8 CSC files, and I deleted out everything for other carriers so the new file is only about 120mb instead of 300-something.
I can post that up after work if you want to wait, uploading is blocked here at work for some reason.
Have to add that wifi calling still doesn't seem to be working, but VoLTE does since calling does not drop me from LTE. I have no menu settings for either still, but after doing a full reset, reflashing etc I have the wifi calling quick toggle but it doesn't seem to turn on all the way - the "on" color is light-grey instead of white like everything else (dark grey when off) and in the System UI tuner app, no icon is set for Wifi Calling or VoLTE.

Yeah it's in my Exynos T-mobile CSC thread but I've got a better smaller one now. I took a pack that @TEKHD made for the S8+ F variant and switched out the files with Note 8 T-mobile files but there is a little bit left to go to make WiFi Calling work on our N950N, VoLTE works, HD voice works, video calling works, but I'm still trying to figure out what's missing for WiFi calling. It's menu isn't even showing up yet.
Current flashable zip is only 88mb and I'm fairly sure whenever I figure out the remaining files that need to be copied over it won't be much larger.

I'm about to do a factory Odin flash to stock and test the latest version - if it works properly I'll post it up with a link - though I don't want to step on anyone's toes since the core script and idea belongs to TEKHD.
Fair warning as far as right now I still haven't figured out why WiFi Calling is missing, I set up this the same way he has his S8+ pack for their F variant aside from adding a few framework files that I found referenced in the Tmo Wifi Calling apk that don't exist on a factory Korean N950N but are on the Tmo ROM, and my theory if this next attempt doesn't enable WiFi Calling is that the N950N is fundamentally either just missing more files that need to be in place for it to work and I haven't found them yet, or that it has different/incompatible versions of some files that the T-Mobile Wifi Calling needs to function.
In other words I have 2 more things to test, then I am going to try fully wiping, flashing an N950F-based ROM and apply the T-Mobile WFC pack to that, since the S8/S8+ options that enable it for those folks are for the F variants, not the N variant but the F and N have the same hardware.

Sounds good. I went through the same things with my Note 2 years ago. I figured it out and got WiFi Calling working.
Fwiw, I have no interest in Wifi Calling on my Note 8, as my signal (also T-Mobile) is always good, and I use Hangouts (or whatever) when I'm on Wifi, for free calling.
I don't have Note 8 yet, but will order soon from the same seller as you.
Do you have any other suggestions for getting everything up and running for T-Mobile (except WiFi Calling), or is simply flashing the CSC file?

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.

https://www.sammobile.com/firmwares/SM-N950U/VZW/download/N950USQU1AQI5/188972/
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. 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 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.

(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?

Sorry man! I over looked the wifi calling. I don't have wifi calling at all. But I have rest you mentioned working fine. Caller ID, Samsung Cloud, Samsung visual voicemail.

for samsung cloud, cant you just install it?

Guys, Samsung Cloud is already there but hidden, to get it to show, do this:

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.
edit. i guess i failed to read you short post... i see "prior to flashing" spelled out for me right there....
