What is an eSIM?
An eSIM (embedded SIM) is a digital SIM already built into your phone. Instead of inserting a physical card, you download a mobile plan by scanning a QR code. It works just like a normal SIM — but there's nothing to ship, insert or lose. Most recent iPhone and Android phones support eSIM.
