What is an eSIM and how does it work?
A digital SIM built into your phone that you install with a QR code.
An eSIM is a SIM card that's built into your phone. Instead of inserting a plastic card, you download a mobile plan by scanning a QR code or entering an activation code.
Your regular SIM stays in place, so you keep receiving calls and texts on your usual number while the travel eSIM provides mobile data abroad.
