According to ATT and Samsung the SM-950u is not att branded, they are been sold in swappa as such, i bought one and found out wifi calling wont work on this device as even do it has att firmware and the bloatware it wont provision. any ways to get this done by flashing the wifi calling provision from att
I had this working by flashing the att fw to a u1, and using my att sim, then i changed my imei to an att s7, but it stopped working and my ims registration turned off. I think they suddenly can cross the sim to the imei and block it. The imei on my account updated to show my u1 on its own.

But a S5(SM-G900W8) second hand that was described as unlocked on Jan 5. From the kijiji ad looks like they were using Telus. Put my Fido SIM and and off to the races. Except it wouldn't update. Flashed with ODIN to Telus firmware from SAMMOBILE. Still working fine.
Until Jan 14th. It just stopped working. Says unregistered SIM. Tried that sim in a G3 and it works no problem. Tried working SIM from G3 in S5 and no go. Took it to Fido store. No help but they did give a new sim. Can read SIM information using app.
Not blacklisted with Fido/Telus/Bell/Virgin/Koodo. Called them all. All of those providers have no information on phone when searching by IMEI.
There is a Bell TV app on phone so I thought maybe it was originally Bell and went to a store to see if they had any info. No info but girl in store tried her bell sim and it worked. I assumed that somehow in the firmware/software upgrade process it had lost it's unlock and must be back locked to bell. Tried to unlock it from Bell but it fails says IMEI not in database(from internet unlocking service).
Still thinking it might be locked called all providers mentioned above to see if they know anything. Nothing. Sidenote when I put my Fido sim in it just says unregistered SIM. Does not pop up for an unlock code or anything.
Tried a friends Rogers SIM. Unregistered SIM. Drove to Telus store to try a SIM. It worked but no service because it was not tied to an account(but did pull Telus APN's from connecting).
So it appears as though Bell/Telus SIM's work. But Fido/Rogers say unregistered SIM.
Called Fido again and they had me go through all the manual APN setup etc. Then something about sending a new signal to phone from Tower to reset network settings. Didn't work. Fido has no answer for me at all. But yet it did work on Fido for 9ish days.
I'm stumped.
Bueller?
Did you ever fix this issue or find the cause of it?
Recently I got an S8 and I ported over my number to freedom from fido.
I thought the wifi is available on S8 but it is not.
Does anyone know when wifi calling would be available for S8?
The S8 supports VoLTE and WiFi calling, however it's upto the Carrier to enable the feature. I'm on Rogers, with my S8 I have WiFi calling and VoLTE working. However people who have unlocked S8's on Rogers won't get WiFi calling or VoLTE because Rogers blocks it on phones not purchased directly from Rogers.
Actually Rogers does not block any phone that it is not purchased from roger's itself.
I have been with Fido for 12 years and last year I got a brand new S7 edge from the Samsung store in Sherway Gardens.
The VoLTE and Wifi calling worked out of the box.
I called Fido and I wanted to make sure to register my new IMEI and the woman on the phone told me that the IMEI is automatically registered after few days
but just in any case she did regestered it.
I kept my Fido for few days before I port my number to Freedom and the S8 I got from Freedom worked in Fido (I unlocked it)
and the VoLTE and the wifi calling. Although what I did was to change the CSC. Then I changed the CSC back to Freedom and I did
not have the option for the wifi calling.
What I have noticed is that the phones that are sold in Canada (At least the major models ) are the same and the only difference is the CSC (network customization)
code that are come preloaded.
Now Freedom is a new to VoLTE and Wifi calling so I am waiting to enable the wifi calling in S8

check this thread, Rogers will not support VoLTE and WiFi calling on phones NOT purchased directly from Rogers:

I don't know what the thread says but I can tell you that I have been with Fido for 12 years and last year I bought from Samsung Store a S7 and after few months an S7 edge
and on both phones VoLTE and wifi calling was working just fine.
I never had a single problem.
Also I called Fido representative and confirmed that both services were configured on my account with a problem
Also few days ago when I got my S8 from Freedom (I sim unlocked it) I put it on my Fido sim card
and VoLTE and Wifi were working again just fine

I was wondering if there is a way to get VoLTE working on a factory unlocked S8 that is using a AT&T Straight Talk SIM card. Right now when I make a call, the data goes to 'H'.
Anybody?
I'm not sure if it's possible but have you tried carrier switch your unlocked S8 to AT&T firmware. That's the only way I could get it to work on my unlocked S8 but I do have AT&T though as a carrier
How did you get it to work on att? I am on att as well and it does not appear to be working after carrier switching my unlocked S8 to att branded also wi-fi calling does not work.

It worked for me the first time but then the second time I went back to the Oreo beta they went back to AT&T I was only getting H after that when I was calling so I had to borrow my wife's phone IMEI and they provisioned it and it worked again
so how exactly do i go about doing that? I assume this involves calling att or going into a store and giving them the imei from another phone? Does the imei you use have to NOT be already used or can it be in use by 2 phones at the same time? Also so far we have not even told att about this phone we have just moved the sim card so wouldn't they still have the imei of the old phone or do they pull that automatically OTA? If they do pull it automatically then whats preventing it from getting updated again?
So, after reading through several different threads on several sites, the only DEFINITE answer to getting wifi calling on an unlocked S8, even after rooting, flashing, etc. is that you still need to get an IMEI from an ATT branded S8 in order to get the wifi calling, volte, hdaudio, etc. that come with a ATT branded S8??? Has anyone had permanent success flashing the ATT Branded firmware to a unlocked ATT S8 getting wifi calling, etc. to work without having to get a new IMEI? Don't want to have to go through the pains of having to return my unlocked S8, paying the stocking fee (if required) and paying the additional $100 or more for the ATT branded phone. Thank you in advance.
I called AT&T and switched my IMEI to an AT&T S7, but as soon as I connected my unbranded S8 the system automatically switched back to saying I had an unrecognized phone. I don't know what would have happened if I'd used the IMEI from an AT&T S8, because I don't have access to one.
I recently got an AT&T prepaid sim card and I flashed my Canadian W model to G950U (AT&T) branded firmware. I am trying to activate the wifi calling and I get an error APP0008. I called AT&T and they keep telling me that the phone is not an original AT&T and wifi calling is not supported on non AT&T phones.
Has anyone seen this error and how did you resolved it.
Wifi Calling is exclusive for PostPaid accounts. I have Prepaid and they do not activate it for me.
Finally I was able to enable wifi calling on my S8 and Note 9. Both phones have been flashed with the ATT firmware. I have a prepaid account with ATT and I use Canadian models S8 and Note 9.
Of course I cross flashed them with the U firmware and my account has been provisioned for call waiting
Let me describe the problem here.
When I try to enable wifi calling I get an error message APP0008. When I try to read the network settings for call forward and call waiting Samsung says Something went wrong. There is a sim error or network error.
So for some reason Samsung phones can not read the settings from the network. Some people report that if they restrict the phone in 3G mode only are able to read the settings but for my did not make any difference.
My solution was to put my card on an iphone and try to see the call forward settings and enable/disable the call waiting. I got an error as well.
After that I put my sim card to my Samsung phones and suddenly the phones were able to read the network settings for call waiting, call fording.
At the end I went and enable the wifi calling and the phone brought up the ATT page for wifi calling and everything was ok.
The question here is what the Iphone is doing to the sim card/or network and then samsung is able to read the settings and enable the wifi calling?
For people that have problems enabling wifi calling on a ATT firmware (U models) and on Samsung phones and get the APP0008 error try the above
