For the major US carriers, since they shut down 3G, VoLTE is the only way calls work. Which meant that a non-VoLTE-but-4G-capable device can no longer make 911 calls. I was using a Samsung S5 running LineageOS for a while with Google voice for calls, but the no 911 thing is one of the main reasons I finally moved to a different phone. The S5 supports VoLTE but only with stock firmware.

Auch, wasn't familiar with that, haven't been in the US for a while. At least around here (EU) is not enabled by default on phones you buy off the shelf. I'm not sure about phones bought from the carrier.

  What part of EU doesn't have VoLTE enabled? It is definitely widely used here in Sweden, though they simply forbid phones unable to do emergency calls over WiFi (including existing phones, which forced me to buy a new one. That was very irritating).

    To explain myself better: it's readily available on the carriers, but if you just buy an off the shelf phone and put a SIM on it, it won't be enabled automatically (at least in a couple countries I tested it), and you'll need to go to your Android SIM/carrier settings menu and enable it yourself.

  LTE was originally designed as a data-only upgrade to 3G. It became the full on successor to 3G, but launched with voice spec left as TBD. It eventually got defined, but ended up being a cursed nonstandard SIP-VoIP software thing, and so a lot of carriers and networks implement whitelists for VoLTE phones to manage anxieties around it.
