I'm pretty frustrated with the current Situation.
I got pretty used to Volte and WiFi calling. My old Phone gave Up its ghosts and so I ended up with my Nokia 8.1 which I'm pretty pleased with.
If there just weren't the issue with lack of Volte and WiFi calling.
HMD states the Phone must be specifically supported by my Provider but my provider stated that Volte ist generally enabled and hmd needs to Implement it in the Firmware.
So me as a customer ist caught in between 2 Parties with no way of knowing which Party is right and how to push things forward.
My provider is o2 Germany btw and Volte and WiFi calling worked like a charm with the old Phone .
