Hi all, I have been searching on the multiple posts on here about this topic, but nothing has helped.

As the title says I have a Samsung Galaxy A55, its unlocked and has the latest updates done on the 5th of March (Android version 16, UI version 8.0). 

I have just moved to Three network yesterday, but since I put the Three sim in my phone WIFI calling has stopped working. My old network/SIM worked with WIFI calling in the same phone though. And also my new Three SIM in an older phone works with WIFI calling.

When I had my old SIM in this phone, when I went to settings>connections> WIFI calling option was there, but now its not there. I still have the option in my drop down bar to toggle WIFI calling on/off, and the same with phone>settings>call settings, but when I switch these on nothing happens.

A few times the WIFI calling symbol has shown in the status bar at the top when i pull down, but it has disappeared soon after. When this has shown, I have attempted to make a call to see if the `WIFI call` will show, a WIFI symbol with the phone symbol appeared. So possibly that means it has worked sporadically? But on my previous network when I'd make a WIFI call, when swiping in the dial list to make a call, writing would show saying 'WIFI call'. 

I have tried lots of advice I've seen online, such as....

- Turning on/off WIFI calling

- Checking for updates

- Resetting network settings

- Soft reset

- Turning airplane mode on, then switching WIFI on

- Switching off WIFI calling, then restart phone & turn WIFI calling back on

I also seen advice to go to settings>about then scroll down to Network and tap it to see it will update. opposite Network it just says '3' and when i tap it does nothing. Am I checking the correct place, as shown below?

SIM 6 ...............................................
Phone number 
Network   3
IMEI
............................................................

I hope I've explained this as best as possible, if not I'll answer any questions to explain further, any help would be very much appreciated, thank you.

Same no Wi-Fi or Bluetooth on Galaxy Fold. Ever since they're update it'll come on once in a while but only for 5 to 10 minutes at most and then it shuts off. Samsung's doing nothing about it but pointing fingers
