Wifi calling issues

[NeilC]

The WiFi calling feature on my Samsung Note 20 Ultra has become very intermittent and doesn't appear most of the time. It worked fine previously but recently it is very unreliable. I am told this is Network provider driven feature and not a phone issue, can anyone please help as I rely on WiFi calling at home as I don't get a network signal.
Thanks
Neil.

Samsung have rolled out a fix for some of their phones in the January security update, so check if it's available on your phone yet.

If not, try turning off and remove sim, then turn phone back on and replace sim when phone has fully booted up.

Thanks for the advice, the update had already downloaded a couple of days ago. I tried removing the sim card and rebooting the phone as you suggested and it appears to have worked.
Many thanks.

Should be OK now then @NeilC
