Same problem since S9 Plus, O2 UK does not display VoLTE or VoWiFi icon !! I wrote to them on the forum but did not answer anything.

I probably did not explain correctly. O2 supports VoLTE but does not display an icon like other operators, instead it just shows 4G, 4G+ or 5G. It is easy to check, if during a call you still have a 4G / 4G+ icon, then VoLTE works, if it changes to 3G, then it does not work. But the problem remains a problem - there is no normal VoLTE icon!
