jesteraero: No I haven't tried rooting. But I'm waiting for a Kogan sim.
Theres info that previously someone had a phone from Australia that wasn't sold in NZ.
Volte wasn't working on any of the telcos here.
They tried a Kogan sim and managed to have VoLTE and wifi calling work (even though Kogan uses the Vodafone network in NZ).
I'm thinking if Kogan is listed as a MVNO in Australia where pixels are sold then their carrier info is probably loaded.
Anyway, I am waiting for a sim from them to try.
I have a PH-1 which was a very vanilla / pixel like phone sold briefly before they went out of business. This was never sold officially in NZ (or perhaps even Aus), and VoLTE and VoWIFI does not work on any of the main carriers in NZ, despite having the options in the firmware.
On Kogan however, VoLTE and VoWIFI work without almost without issue. The only "issue" is that when ringing some carriers over VoWIFI, the ringing tone is a little different than the normal ringing tone - it just sounds different. I do not consider that a real issue.
Very interested to see if similar behaviour occurs with the Pixel 6's.
