What’s the point of the dual sim feature if you don’t have control over both lines independently ???? It’s 2023 I still don’t have my hoverboard (b2future said 2010) I can’t set individual app notifications sounds and now I find out I can’t control my biz line independently of my personal line. I drank the apple koolaid and for the most part I like it. But C’mon!

While admittedly not elegant solutions:
You CAN easily turn each line “on / off” independently. (This of course also turns off SMS)
You MIGHT - depending on your carrier - be able to fairly easily “tune” your incoming call handling using “Star Codes.” (use with caution, some functions are quite powerful; use your carrier’s authoritative reference … not simply an “internet post”)
Different ringtones for each active SIM is near the top of my own wishlist.
Dual sim do not disturb
