No, you can't. You can only physically insert one SIM into the tray. An eSIM is an electronic, and therefore non-physical, SIM that can be activated. The component is already built into the circuit board of the iPhone.

yo, an eSIM (you have to ask your provider) and a normal Nano Sim.

But now I am confused. The product description under SIM says "Dual SIM" in contrast to the iPhone 11, where it says "SIM + eSIM".
