Why is the VoLTE option not showing on my iPhone?

What do you mean it’s not showing?

Not showing where?

If you mean in settings, it isn’t there because it is no longer optional on most carriers. It is on. Full stop. You can’t disable it. In the US, no cellular carriers support devices that don’t support VoLTE.

old issue, new issue, what changed?

VoLTE is voice calls— it is 4G LTE network. This is old option to use VoLTE, Apple iPhone 11 or newer(?)
