How do I activate VoLTE on my Android phone?

Make sure that you have the latest software version, then VoLTE is automatically activated when you have 5G.

For VoLTE to work in a Samsung phone, you need to install One UI 6.1 or its later version. If you have an Android phone which is not Samsung, you need the latest version of Android (Android 16 or newer).
