Wifi Calling on AT&T?

Is it possible to enable wifi calling on a unlocked D6603 that has an AT&T sim inside and already downloaded the network settings?

WiFi calling enabled

I just found out this evening that I was able to activate WiFi-calling on my Nokia 8 here in Denmark on the Telenor network. This compliments the VoLTE feature that was enabled in some months ago. I run Android 8.1 and my model number is TA-1004.
It is only available if your network enables the SIM card to use it.
It also needs a proper configuration from the network side. Network needs to accept this phone as a VoLTE and VoWiFi capable.
Wifi calling issue on Airtel, India network.
Hello,
I am on Airtel network in India which has recently enabled Wifi calling. I got it enabled on my SIM card but I am not getting the option to enable Wifi calling. What I understand going through this forum is there will be a option under Settings -> Network and Internet -> Mobile network -> Advanced but I am not getting the same. I checked in another mobile set (OnePlus 7) and wifi calling worked on my SIM.
I am having TA-1004 running Nokia provided Android 9 with security patch up to October 2019. Can anyone here guide how to solve this issue ?
Does this rollback to oreo helps on "restarting issue" in Nokia 8?? Or can someone solve this problem please..

OnePlus 6: How to Enable Wifi Calling (on T-Mobile Network)

Wifi calling allows you to make Calls and send SMS when you don't have a Cellular Signal, and while traveling out of the country- as long as you have a Wifi connection.
The OnePlus 6 (and 6T) isn't yet officially supported on the T-Mobile devices list. Link here:

Note: You should already have Wifi calling activated on your account! You may need to log into your account online and activate it. These steps should work on other networks also.
See Images below
Go into Settings
Sim & Network
Select the SIM
Enable Wifi calling
Set Calling preference to "Wi-Fi preferred"

Hi!
I'm trying to enable voice over WIFI, my network provider supports it, it was working fine with Iphone6s, now i switched to Note10 and i can't enable this to work.
On the Mi 9 you need certain codes: https://forum.xda-developers.com/Mi-9/how-to/wifi-calling-volte-mi-9-t3917887
Maybe try those and see if you have any luck?
May I ask where you bought your phone and in what country and what network you are trying to use wifi calling?
On the Mi 9 thread, there are reports that wifi calling doesn't work as well with all networks; eg with Vodafone UK the option to prefer wifi over mobile network isn't available, so wifi calling is available only when there is no mobile signal.
Hi. I entered the codes, the option is there, but it's not working. I'm from Slovenija, my operator is Telekom Slovenije, the phone is from Gearbest store...

No way to get Wifi Calling working with non-network phone ?

Hi,
I found one short thread about this. But are we sure that there is no other way to use Wifi Calling ? I have a non-network phone, an LG G7. I don't want to change it ATM. Why do the networks tie Wifi Calling to the firmware like this and is there any way round it ? Cheers.
With my carrier, Wifi Calling only works with its SIM on any phone with any firmware on which Carrier Services runs or can be installed. No SIM no Wifi Calling.
You can look for services that will connect you via vpn and allow WiFi Calling, but you are always identified. Calls cannot be anonymous.
