Data Usage Switch option not available.

Hi

I have S24 Ultra. I have no option available for the Data usage Switching as attached in the screenshot. 

How can I switch data without changing my primary SIM.

Are you saying "Data switching and backup calling" is not getting enabled ?.

Can you elaborate the issue please.

I have attached the older version in my Samsung note where I was able to set the preference. But now in my s24ultra I do no have this option.
