Yes I have wifi calling. Unlocked BTU
I'm on EE
Wi-Fi calling
Did you have to enable calling on the S8? I checked an S8 (BTU) demo phone at Carphone Warehouse and could not find this option. What process did you go through with EE to get it working and are you happy with it? I cannot get a signal indoors and want to buy unlocked S8 to use use WFC.
Thanks, Mike
I am on BTU with Three - but WiFi calling is not enabled;
The XEU (UK unlocked from 3rd party seller) variant has a Wifi calling option in call settings. This works for EE but I had a new contract and Wifi calling didn't get enabled until a few days later. VoLTE didn't work at all on XEU with EE, so I installed the EVR firmware for that. Maybe try sticking the VOD firmware on yours?
For Vodafone all you need to do is call the support then ask for wifi calling issues.
Ask them to send you the configuration to update the provisioning and the wifi calling option will appear instantly.
One question to people in the UK with any Carrier unlocked Note 8. Is the RCS or Chat in your stock messages app?
Thanks
Another thing not to overlook (if you are struggling to find the settings) is where you're looking for it.
On my old N6P it used to be in the advanced WiFi settings but with the Note 8 its in the phone app. Took me a while to figure that one out!
I have sim-free Note 8 and wifi calling on EE.

samsung s10+ smg975f
There's a way to set it on my phone, but I am in the U.S. on AT&T. All I do is turn wifi calling on in the drop down toggle menu on the notification shade when connected to wifi.
I used this app https://play.google.com/store/apps/details?id=com.wikimediacom.wifi.calling&hl=en and it surprisingly works on my s10+
On my old Note 8(dual sim), one of my operators allowed the setting and the other did not. I just enabled wifi preferred and swapped my sims.

XQ-AT52 VoLTE or Wifi Calling in Canada

Hello,
I have the XQ-AT52 in Canada and using it on Fido and works on their LTE network just fine, but I do not get the VoLTE nor Wifi calling options to allow me to enable them. Anyone know if its possible to get them enabled? If so, how?
good question...i'm thinking about the same issue for German provider but befor ordering it 0_o
You should
dial *#*#4636#*#*
choose Phone information.
click " Phone Information"
If your provider support Volte, you should see switchable "VOLTE Provisioned"
Switch it on and Restart the phone and you are done
ps: my provider doesn't not support Volte and my option is not switchable

My provider does support VoLTE and wifi callling, and I have those capability on my old phone, Huawei Mate 20 Pro. So it looks like the hardware or software of the XQ-AT52 does not allow VoLTE to be turned on, atleast in Canada.

Question No WIFI Calling Option

WIFI calling option is not available in my G998B/DS Exynos only on 1 operator Mobily ( KSA) its available on other operators ..
But the issue is that when i am using same SIM on my iPhone/android mobile WIFI calling option is available ..
its activated and available by Operator but only in my mobile its not working .. same SIM used in other mobile WIFI calling is available ..
Had the option enabled on mine, but WiFi calls would only work in Airplane mode, got around it by setting WiFi to preferred on the EpdgTestApp.
