Why is Three disabling wifi calling preference menus?

[TheGreatMothra]

Hi,

I've happen to work in an area where there is really terrible signal. I rely on being able to use wifi calling at all times when I am there. The current policy of my phone appears to be to use regular cellular network even if there is only the tiniest of signal. This makes sending or receiving calls basically impossible.

There is a menu in android phones which allows users to specify that they would prefer to use wifi calling always, however it appears that Three has disabled this menu as part of their carrier settings. Why is this, and what can be done to either work around it, or convince them to turn it on? I'm not above moving networks if that is going to be the only solution.

i know this is an old thread, but I've just switched to three and noticed the same issue, after enabling wifi calling the calling preference option is not displayed.
(In Settings network/sims/3UK/Wifi Calling, there should be a 'Calling Preference' option which then gives the option to prefer wifi or mobile for calling.
I previously had it on O2 and also on Lebara, but it's not there with 3 as shown in the attached pictures.....

The easiest way to get to the menu is to go into settings and search for "calls preference" you'll see the menu listed in the "others" section. Click that and you'll see this page:

The greyed out calls preference menu normally contains a "prefer wifi calling" option when it is available.

Thanks @TheGreatMothra, if you can share the software version, and whether this was supplied by Three, initially supplied by another provider and subsequently unlocked, or supplied unlocked from elsewhere that'll be a great help in getting this checked out further.

I have found how to turn wifi calling on and off but there is nothing on my S21FE that allows me to prioritise wifi calling. It's odd that there is a switch will that tells android to switch between wifi and cellular data depending on which signal is stronger. It seems reasonable that wifi calling and cellular signal should be treated in the same way.
