#2Most of the USA is VoLTE-only for a ~year already.
For other countries see https://en.wikipedia.org/wiki/3G#Phase-out

#3One often unexpected consequence for tourists visiting a country that has executed a complete 2G and 3G shutdown is that they won't be able to make voice calls, even if their phone and plan supports IMS (i.e. VoLTE) when at home.

i discovered a month ago that there is "VoLTE Roaming" that phone must support in order to be able to roam. looks like it specific for phone models/operators and not generic

No, the 2G network is still running at least for T-Mobile. I happened to check earlier today.

New T-Mobile SIMs haven't been able to work in 2G phones for a bit now. If you have an older SIM that's still active you can use it in a 2G phone but they don't want new customers using non-VoLTE devices on their network. They also haven't invested in expandning their 2G footprint since about 2015 when their network was significantly smaller. The 2G service will be discounted in April.

Even 2 years ago, I got an iPhone 5 from somewhere and found that because it didn’t support VoLTE, no carriers would support a new connection. They would support you if you were already on board for a little while.

#8My main concern with these higher frequency connections is that they require a lot more power to run. So we can’t have phones that will last weeks without charging.

For some reason lots of Android phones (even the Pixel models from Google) seem to use a whitelist approach that is quite restrictive regarding where VoLTE is supported. For example at least up until recently (and probably still the case?) Pixel phones only supported VoLTE in countries that were in the list of countries in which the Google store official sold Pixel phones.
Meanwhile newer iOS versions seem to nowadays have generic VoLTE (and even VoWiFi) support that even works for smaller MVNOs without an iPhone carrier profile (as long as their VoLTE implementation somewhat conforms to standards).

Turn off cellular and wifi on your phone. I bet it won’t last more than a few days anyway. I don’t think radio power consumption is the barrier keeping us from weeks-long battery life.
