I got an SMS from Optus telling me "Your phone comes equipped with the VoLTE and WiFi Calling enhanced call features. We'll be setting these up for you within the next 4 hours. You can then turn them ON and OFF via your mobile phone's settings."
I can find the WiFi Calling settings and I have turned it on, but eight hours after receiving the SMS, I cannot find the VoLTE setting mentioned in the instructions linked in the SMS.
The Android instructions are for a Samsung Phone, so the screens don't match, but I can find nothing on any Pixel forum about VoLTE setting.
Can the hive mind help? Do I need to turn on a separate setting for VoLTE or is turning on Wi-Fi calling on a Pixel enough?
