Go to April 2022 and this is still an issue with my dad's bought June21 and mine bought Feb2022. They were bought from Samsung online shop. The function key/toggle on connections doesn't exist. Vodafone have enabled and asked me to put my sim back in my old A5 2017, voila wifi calling function is there. Vodafone therefore proved Samsung problem, either manufacture fault or told me to ask Samsung to do a factory/master reset to see if wifi calling action could be seen. If not they stated definitely 100% a phone manufacture fault. Samsung technical did and were very surprised when. Voila, no wifi calling on or off toggles, not mentioned in connections at all. It is not there as a choice!! She told me it is a manufacturere fault!!! I am now waiting for higher technical person to ring me as I want a replacement for both my dads and my phone, as we live in countryside with bad signal and NEED this function offered.
