What is eSIM?
How is it different from a physical SIM?

eSIM is a digital SIM built into your device—no physical card needed. Scan a QR code to activate. Traditional SIM cards require inserting a physical card.

In short: eSIM is faster and more convenient; physical SIM works on devices without eSIM support.
