If I turn VoLTE on, I don't get the icon in the top tray to show this?
On either sim, ones Vodafone, ones O2

If I got WiFi calling, I can only set 'preferred' on the O2 SIM, not the Vodafone SIM?

If I go into airplane mode and turn WiFi on, both sims show WiFi calling.

The only network that shows the VoLTE logo on Samsung is EE and only EE and O2 allow you to prefer WiFi over cellular for WiFi calling

Yes I have both an EE and Vodafone SIM and VoLTE still works on my Vodafone SIM even though I can't toggle it on or off it's on by default
