Yeah, that’s the fun bit. It’s not that Graphene can’t do calls.
It’s that in Australia, post-3G, “works on 4G” is no longer enough. The phone / firmware / carrier combo has to play nicely with VoLTE, IMS provisioning, and 000 emergency calling. If the carrier doesn’t like that exact combo, you can have perfectly good LTE data and still lose service or get nuked by IMEI/TAC filtering.
Graphene on a supported Pixel is probably the best-case scenario. Sadly, that doesn’t generalise to other phones here. It’s a dice roll.
TL;DR: VoLTE is carrier-blessed black magic. Same bands, same radio hardware on paper…very different outcomes.
Very cromulent system. Much consumer choice.
