To activate your CoreESIM for Vienna before landing at Vienna International Airport (VIE), purchase your preferred plan online. A QR code will be provided via email. Scan this QR code with your eSIM-compatible device to install the profile. While the installation can be done pre-departure, it's critical to ensure the eSIM is only enabled for data use once you are in Austria to avoid any roaming charges from your primary SIM or premature plan activation. This ensures immediate connectivity with networks like A1 or Magenta upon arrival.
