You mean with your carrier
Samsung have had dual sim far longer than Apple, only the Fold has 1 Physical and one ESim. I hope the Z-Flip will too. (Confirmed One eSIM and one Nano SIM for Flip)
I only found out recently that ESim is actually a pain as they are one time use activation so swapping phones or reset means you need a new activation. Not convenient if your second sim is from another country.
For the US market Samsung hasn't really offered dual sim the same way they have offered the rest of the world. They cave a lot to the US carriers a great deal on everything. Without Esim it's a no go for people like me that have multiple lines.
