@Anders_ASUS I would also like to know how to enable it!My operator supports HD Calls, every cheap phone has it enabled but zenfone 6 not.Also VoLTE... The mighty VoLTE... Every cheap phone has it enabled except the expensive Zenfone 6..Thanks in ad...
I received an email a couple of weeks enrolling me to beta. Few minutes later, another mail postponing it to a week later.2 weeks have passed and nothing..
On my OnePlus 5, i activated something via a specifical software, and VoLTE started working..Why doesnt' ASUS have that certification in Vodafone Portugal?!
It's not a ZenFone 6 bug, it's an Messages.apk bug and it's on since I remember, for many many years.I've had this issue since my first OnePlus One! I've managed to get it work by puting a second sim card (borrow from family or friend). Then, reboot...
