I think you missed the point in the post that you are replying to saying carriers have dropped 3G and the only remaining 2G network is also on its way out. Where I live all carriers are planning to phase out 3G by the end of 2025. All but one carrier have already phased out 2G.

We need to forget about falling back to 3G or 2G as that is not a viable solution in the long run. The carriers and phone manufactures have a responsibility to make emergencies calls work well over VoLTE.
