Dual Volte (Voice over LTE)

[ErnAqui12]

This is a little frustrating. I was under the impression that dual Volte can work here when you turn on both options, yet the opposite result. Volte is only for sim 1 even if you turn on dual Volte. If you check on the top right, it will only say VoLTE1 which identifies SIM 1 use. How about sim 2? I tried to test it by calling a number using video call over a regular phone call, not using any supported apps, and it only supports sim 1, not sim 2. What can you say about this, Mr SAMSUNG OPERATORS. I NEED ANSWERS.
