Can't enable VoLTE/ Bouygues Telecom(France)
I can't enable VoLTE.
- Model Name: ROG Phone I (Z01QD / ZS600KL)
- Firmware Version: 16.0420.2003.24_0
- Rooted or not: Nop
- Frequency of Occurrence: every time
Settings is not present in the phone parameters, and when I use the #*#4363#*# the VoLTE settings is grayed and can not be toggled.
I've double checked with my provider, the option has been activated for my line so it should be ok on their side.
