Hi Emma, yes — the iPhone 13 is eSIM-compatible as long as it's unlocked, and you install by scanning the QR code under Settings › Cellular › Add eSIM. Any questions before you go, just reach us at esimtopup.io/support. – Omar

Do I need to install it before I travel or after I arrive?

Tom eSIM TopUp Support

Set it up before departure. Installing needs internet, and airport Wi-Fi is not always reliable.
