Can you explain what automatic data switching is?

Auto Data Switching is a useful feature for anyone using two SIMs—whether that’s two physical SIM cards or a combo of a physical SIM and an eSIM. It lets your device switch smoothly between data lines, even while you're on a call.

When 'Allow Mobile Data Switching' is turned on, your phone can use mobile data during calls made from your voice-only SIM. That way, you stay connected to both voice and data at the same time.

If this setting is turned off and you’re on a call using the SIM that isn't set for mobile data, you won’t be able to access data during the call.

Hope that helps clear things up!
