I've read a few posts about this and it seems a few people have got this working but working through info\suggestions I've not been able to.
To preface:
-WiFi calling is enabled through my carrier
-I have the sim set to prefer WiFi calling
-some Posts said to re-enable WiFi calling after enabling airplane mode my phone doesn't seem to disable WiFi calling after enabling airplane mode
This is important for me while traveling internationally so I don't use up roaming minutes and possibly texts although I imagine even if texts were sent over WiFi they may still count against my limits. I can turn of mobile data and roaming to force WiFi calling but it would just be easier to be able simply enable airplane mode. Why is this a default in Graphene to disable calls in airplane mode?
