Right, so the message to general public (millions of people?) who wouldn't have a clue about any of that - buy a new phone because it might or might not work when you really need it.

Every iPhone since the iPhone6 that came out in 2015 has VoLTE support. Just about every Samsung handset released in NZ in the last 3 or so years has VoLTE support, and a significant number of recent Huawei handsets have VoLTE. Together these brands make up close to 90% of all mobile phones sold in NZ.
I think the fair assumption is that yes we should warn people if the 3G network gets turned off and we purely rely on VoLTE and 4G sites but most won't even notice unless you're either under that 10% or in a really awkward area.
Not to mention 2degrees and VoWiFi is great for home with areas without cell tower coverage so you can fill in the gaps even more!
Also VoLTE is still in it's infancy. Give it time. Give RCG time too to expand their sites. Give telco's more time too they could expand their approved list!
