Over 2G and 3G, voice calls are circuit switched. VoLTE and VoNR are packet switched, over IP, VoIP. Totally different. VoLTE is not as standardised as it may seem from the outside whereas 2G and 3G voice calls were.
Internet access is not regulated as an emergency service.
Does the 5g have the same problems or did they improved it . Because right now that may be a collosal problem if my country ever wanted to turn off 2g ( which to be fair likely wont happen for a long time ).
5G NSA does have the same problems since it's 4G with a 5G hat on, although the handset-side software stacks for IMS settings are slowly improving. 5G SA is still too new really.
5G theoretically replaces 2G for low-power machine-to-machine operations like connected power metres, which is the main reason 2G still exists, but of course requires new hardware.
The many joys and customer issues that happen when an older network tech is retired and the spectrum refarmed to the new standard (e.g. shutting down 2G/3G and using the bandwidth for 4G/5G) are well-documented and a smart operator can do it with comparatively minimal friction, it just takes a long time to do it right.
