Even just switching mobile voice standards is painful, as seen in Australia recently. In theory, you just need VoLTE support to use calling over 4G, but it turns out there is a bunch of other compatibility issues like emergency calling, device software and firmware settings, and carrier side problems that complicate matters.
It’s almost as if volte being a* proprietary technology hurts consumers and a lack of emergency test numbers (numbers that use the emergency system but are just for testing that it works) makes things harder.
