Samsung A34 5G wifi calling

Just joined Smarty with my Samsung A34 5G dual sim. Wifi calling works with both sims simultaneously and 5G on both simultaneously, one is on EE and the other is Smarty. There does seem to be an is...

As above, I'm worried that a caller was sent to voicemail when I was at home with WiFi calling & internet active. Can any of you gurus suggest reasons why that could happen?

I'm in a dark hole for mobile signal, so Wifi calling is essential to me

Many thanks for yr replies above

    If there is any mobile signal available, even if you have WiFi calling on, you will not get WiFi calling (unless you are using an iPhone as they seem to work differently). To guarantee WiFi calling when at home, you have to turn airplane mode on and then turn WiFi on again which leaves mobile data off. Then you will get WiFi calling.

      THANK YOU Sinkers

      That matches my problem precisely, in my nearly NOT-Spot home location.

      This thread is for a Samsung A34; I have an A54 and the behaviour differs a little.
      On A54 quick panel, WiFi does NOT toggle off when Flight mode is turned ON.
      Mobile Data isn't a switch on A54 (now Android 14); it is an indicator only, showing Flight Mode inverted.

      You just have to remember always to toggle Flight Mode on leaving the house
      and then again on returning Home.
      I tend to have Flight Mode ON partly for Battery Saving purposes
      (but I often forget to Switch Flight off on leaving home)

      Could Samsung automate that? 
      perhaps with a new Old/New Behaviour switch in Settings, to give the user absolute control
      For example, New Behaviour
      Every once per 2 or 3, minutes check
      IF WiFi is ON AND has internet access THEN
       switch Flight Mode ON (=Mobile Data OFF)
      ELSE
       Switch Flight Mode OFF (=Mobile Data ON)
      End If

        I have completely automated this. 
        The first thing I did was to change the behaviour of Airplane Mode so that when it is selected or deselected it does not change Wi-Fi at all.

        I did it a long time ago, so I can't remember what the ADB command was exactly but I think it was adb shell settings put global airplane_mode_radios wifi,bluetooth. What that does is to leave Wi-Fi and Bluetooth on when Airplane Mode is on. I also leave Bluetooth on so that my watch can talk to my phone.

        I then used an app called Macrodroid,  which is free for up to 5 automations I think, but in fact I paid for it anyway as it was inexpensive and I was happy to help the author.

        I created two macros one which turns Airplane Mode on when Wi-Fi is connected and one that turns Airplane Mode off when Wi-Fi is not connected. In fact all that does is to turn mobile data on when I'm not connected to Wi-Fi and off when I am.

        This was very easy to achieve and works flawlessly.
