Oops, I accidentally posted in the wrong thread. moving my issue here:
So, I tried to enable VoLTE with Salt (Switzerland), but it just won’t work. The config looks fine:
[root@Xperia10II-DualSIM defaultuser]# getprop persist.vendor.somc.cust.modem0
S32.1
The modem config is in /vendor/firmware_mnt/image/modem_pr/mcfg/configs/mcfg_sw/generic/euro/salt/vw/ch/ and is correctly set:
[root@Xperia10II-DualSIM defaultuser]# cat /vendor/oem/modem-config/S32.1/modem.conf
mcfg_sw/generic/euro/salt/vw/ch/mcfg_sw.mbn
However, enabling VoLTE in the ‘mobile network’ settings just results in the dot blinking indefinitely, staying at status ‘Not registered’.
journalctl logs the following messages when I enable the setting:

Those do not look pretty helpful to me. Is there any log where I can find more information about what’s going on?
