I had a samsung phone in India, the one ui version in india had a mobile data switch option in control panel, where I could instantly switch internet between two different sims. Why samsung US version doesn't have this feature?
Toggling internet on different Sims require a lot of steps in the US version. Atleast give us an option in the control panel to switch primary sim instantly.
you usually do but it's not in the control panel it's if you pull down on any screen and get the pull down panel you'll see two sims there and you can do changes and all that right from there, also usually overseas phones are a little different as usually they're the Samsung chip and not the Qualcomm chip used in US models of which is the Snapdragon processor, little changes like that will affect overall options and controls you have on the phone
