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)

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?

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?

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.

Is there a step-by-step guide to flash Verizon firmware onto an unbranded N8?

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.

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.

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.

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.

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

Yes, I tried it and it works to get visual voicemail. But the option for Wi-Fi calling will only show up if you flash the whole firmware and userdata

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.

Enable Volte and VOWIFI on unlocked note 8

Hi,
I've an Galaxy Note 8 (canadian, SM-N950W), buyed directly from samsung, so it's factory unlock and not in any carrier database.
My carrier offer Volte and Vowifi on S7, S7 Edge, and iPhone. I've an Volte capable sim card, and the volte component is activated in my account whit my carrier (i've an S7 edge in my carrier database).
Now, i want to get it to work whit my note 8. I've done many search on the web, and found nothing that work. I've try to get a shortcut for the ims settings, but it said "not found any csc feature", and the apps won't open.
After that, i've thinked about many other alternative, but i'm not sure if it will work, that the reason i'm asking before doing anything wrong and brick my phone. I know all the samsung carrier-specific function is on the CSC. I can just root and edit the config file, but i don't want to void my warranty, and get limited to 80% of charge.
So, another thing i'm thinking, is to flash the s7 edge CSC on my note 8, that already have the volte function enabled on it. Will it work, because it's not the same model?
I've tried too opening my firmware (downloaded from the web for my carrier), extract it, but when it's time to access the csc img.ext4 file, i get a "corrupted archive" from winrar, that let me doing anything.
Any ideas? Thank!

My logic says, surely the easiest way would be to
flash your carriers Note 8 stock Rom with Odin
If this is possible. This way you most likely to keep
everything official. (Knox etc)
I was in a similar situation.
In my case i had a branded Note 8 and
unintentionally flashed unbranded Samsung firmware.
I did not also have volte and wifi calling etc.
No shortcuts work
So i flash my correct branded carrier firmware
All was working again.
I have no carrier branded bloat, as i uninstalled
them.
This for me was the easiest option
Good luck.

Thank for replying willcor
In your case, can you access the ims settings shortcut? And then, enable Volte and get it to work?
Are you rooted? And does the note 8 is officialy supported by your carrier?
FInaly, can i just flash the csc whit odin so i will keep my file, or i need to flash the complete rom, and loosing my data?
Thank!

Firstly, i am not rooted. Stock branded carrier firmware.
As i already had my sim enabled for volte, wifi calling
etc with carrier i re flashed the carrier firmware
Volte appeared "automatic" after flashing. (Short while later ) For me the easiest way.
It was unintentionally that i had flash unbranded
Samsung firmware.
I was originally on branded firmware.
(Vodacom /Vodafone.)
I soft bricked my device while
beta testing.
When i was on this unbranded Samsung firmware
i noticed that there was no volte, wifi calling
and no stock Hiya spam software. etc.
I used QuickShortcutMaker to try and enable
shortcut to wifi calling. No luck.
I'm only suggesting you check this option out
... if possible, then surely it the best way to go.?
Further just flashing to change CSC gave me all sorts of
issues.
I landed up having XEF (France) and my device showing 32 gig storage.! Instead of 64 gig.
then flashing again i landed up on XFE (SAMSUNG)
Sorted storage out to 64 gig.
Then again i Flashed carrier firmware
4 x files ( did not flash home CSC but the other CSC
which resetted device and all is well and knox 0 x0
Bottom line is that
all my previous devices are rooted. So i knew what i was doing.
When i soft bricked my device etc.
so i did not panic.
So i suggest make sure or
look for a relevant video etc on YouTube
if not sure
Yes you are going to lose your data. So do a backup.
Flashing the "home CSC" basically is a dirty
flash.. You don't loose anything.
Which i think is not going to help you.?
Good luck.

Hi,
I've flashed the firmware of an operator that support the note 8, but still not any settings for it in the phone app setting. Can't still access ims setting too.

for me the ,the best option /scenario would be .....
1) Your service provider that you enabled volte ,wifi calling etc with .
2) Further your sim requirements ,for me i had to have sim 64 or higher ( with correct CSC of carrier .)
3) Then obviously that same service provider ( above ) stock Note 8 firmware ,if compatible with your Note 8 model /device etc .
According to what i experience surely , above should be enough to get it enabled .?
Plse note.....
i would not use another carrier firmware etc ,
(as in this case) just because it should have similar firmware .
Try to align your options ,to make it easier .!
This for me should be an key option ,not another provider that has similar functions etc .
Remember you got no root ,would prefer to keep knox 0 x 0 etc .
so your options are limited .?
good luck

Hi,
Still not getting it to work. But today, i've noticed LTE+ icon appear intermittent. It's switch to 3G when i place call.
No any settings of VOLTE.
Can't find any solution to root my phone (snapdragon), because i've the new update. I'm pretty sure it's a way to get it to work, but don't know how. It's just software issues because my operator was activated it in my account.

Hi,
Finaly, after 3 !!! factory reset, gessing whit 3 different carrier, i've activated it, i've it in the settings.
Now, when i make a call, it switch to 4G. I think it's the APN. I know my carrier need 3 apn for the VOLTE, and still have only one. I will try to find the 3 apn setting today.
For the vowifi, i see it in the notification center, a toggle to activate it, but it's do nothing.

I've successfully found the ims, there are 4 for my operator. But i can't find the IMS APN type in the option given in the phone.... How i can enable it?

If you want it to be easier call your carrier and have them add the imei # to their database then the imei will be whitelist and reprovisioned...then you can just use the unlocked firmware or the full carrier Firmware...

I have posted many times with the same info...Several others have as well..
Thanks for sharing though...just search IMS BlueFox721 in XDA search and you will get more info than the video explains as there are other settings to do as well..
Thanks again for sharing

that video and related info is only to add the missing features if you are not on the right csc.
but it wont fix the issue where the carrier is only allowing imei from phones they sell to use these enhanced voice features. In the case of Rogers and others, you can try calling them all you want but in the end they wont do squat to white list your imei. maybe some other providers will yeild to your requests but Rogers is know to not white list non carrier phones.

I successfully got HD Voice turned on and working. But no sign of Wi-Fi calling. I was searching through shortcutmaster and came across a menu where I can turn on wifi calling. It isnt grayed out, however it wont actually toggle over. The screenshot posted is from tapping the menu dots in the top right part of the screen. I assume I need these filled in to enable it. Any ideas on how to populate the right info. Im on verizon, but got the Note 8 from Samsung, carrier unlocked. SM-N950U1

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....
