So I've activated Wi-Fi calling for my sim (physical SIM, not esim) on my pixel 9 pro xl and it doesn't seem to work at all, either in with flight mode enabled or disabled. I've checked with my carrier and they support it, and I've checked the settings in my OS and it seems like it is all set up fine, but nothing seems to allow it to work. I'm not 100% sure if I'm just missing something or if there is a bug, or if it only works with 2G enabled, or if there is something wrong because of my carrier or something weird like that.
Has anyone else got this issue, or is anyone else able to reproduce it, as I'm not sure if this is just a me thing?
