I am testing a new SIM : Bouygues Telecom in France, using Xperia 10ii
A first try at enabling VoLTE in the SFOS parameters resulted in a blinking button so not apparently working.
The command “getprop persist.vendor.somc.cust.modem0” gave S7.2
if I go through the directories under
/vendor/firmware_mnt/image/modem_pr/mcfg/configs
I can find a reference to ‘Bouygues’
and if I go through /vendor/oem/modem-config/
I can find S7.2
and the modem.conf file seems to report correctly the line “mcfg_sw/generic/euro/bouygues/vlvw/fr/mcfg_sw.mbn”
So I wonder what to do next to try and enable VoLTE ?
