Hi

I am using a SAMSUNG Galaxy S21 Ultra (single sim, Korean Version) phone. My sim is 4G and My operator provides VoLTE service to the other (S21 Ultra, Dule sim version phone) Devices. When I am going to enable the VoLTE under mobile network there is no option for enable that.

Please Help me with this issue.WhatsApp Image 2023-07-10 at 10.35.12 PM (1).jpeg

Have you tried to see if VoLTE works because I had 2 SIMs in my phone and only 1 network allows me to toggle VoLTE on and off but VoLTE works on both SIMsScreenshot_20230711_142800_Call settings.jpg

Some networks don't allow you to toggle VoLTE on and off only 1 of my 2 allow me to do so. Does VoLTE work on your phone when you make a call does it stay on LTE or does it drop down to 3G?
