I was trying to use VoLTE in my phone but eventually landed up with result:
- CyanogenOS can run VoLTE based SIM card
- CyanogenMod can't run them.
Tried
1. Setting LTE Only option in ##4636##
2. Setting APN in Sim Settings
3. Also kept the VoLTE in SIM Slot 1
But nothing worked in CyanogenMod.
Does any one have idea how to use both VoLTE and CyanogenMOD both? Currently my phone's CyanogenOS is allowing me to keep only one at a time :)
But I want to use cyanogenMod as it is marshmallow and nightly build updates are released.
