What’s the use case for this?

Buy two iPhones and make Apple more rich?
I would use this with my old iPhone 13 Mini, forsureeee. I got excited for a minute until I realized they wouldn't release the software on an older device, too bad.

But I definitely see someone using a Mini iPhone paired with a Max. Or Ultra / Fold paired with a base model iPhone.
 
I would love to have an iPhone 13 mini for the weekends and the upcoming ultra for weekdays. I love the idea of having a small phone that I am less tempted to use when I am with my family and away from work. That said, this probably won't come to the 13 mini in which case I have no use for it. 😆
Sammeeeee. I got excited for a second then realized it would never come to the 13 mini.
 
Isn’t this just what swapping out a physical SIM would have done? Funny how they take something away and then bring it back announcing it as a new feature…
