S21 single sim

[Bulb3]

My Samsung galaxy s21 5g bought from the USA only supports single sim.

There's neither a slot for sim 2 nor a 2nd imei number. 🙄

US model has single sim only.... One UI 4.0 will get you esim option which will make it dual Sim.

My S21 has only a single sim, and the model number is SCG09.
How can I enable secondary sim or esim???
