VoLTE works fine, its the ridiculous rollout strategy that requires every phone to have specific carrier settings in the firmware. This ends up in ridiculous situations where some phones will work on some carriers with VoLTE, but not others (despite both phone + network supporting VoLTE), depending on what firmware you have. I'm not sure if this was just an Android problem and Google totally dropped the ball, but I cannot understand why there isn't a central database that gets pinged for VoLTE settings dynamically and the phone uses that. Instead, it seems to be need to be shipped in the OS. iOS is totally fine; but this has totally killed adoption on Android. It's improved recently at least in the UK (last two phones worked out of the box), but previous to that it was a total farce.
