> It looks like signing up with a proper VoIP operator and paying a few bucks a month more is now the way to make sure you have voice connectivity everywhere you have mobile coverage. Without latency guarantees. If you end up on a congested cell and/or are deprioritized you will have noticable latency spikes and jitter. voLTE/voNR and their corresponding signalling have dedicated priority QoS. I did use VOIP for many years over 3G WCDMA and 4G LTE networks as well as WiFi when I roamed between countries and swapped local prepaid SIM cards. Used Google Voice for SMS. My setup worked most of the time but I wouldn't go back to it again unless I had the necessity to. Too many times I'd get calls with big latency.
