VoLTE issue after One Ui 6.1.1.

[JD_Amtonio1]

After updating to One Ui 6.1.1., there is no option to turn off VoLTE calls. Can you please bring it back? I use Galaxy S24 Ultra

“CSC” or “Country Specific Code” is an integral part of Samsung's software.

THL- Thailand

Are you using a Postpaid sim? Because I actually have both and the VoLTE only appears with my Postpaid sim, if I use the prepaid sim that VoLTE is not there.
