Configuring your CoreESIM for Milan is straightforward and best performed before you depart. Upon purchasing your plan, you'll receive a QR code via email. Simply use your smartphone's camera to scan this QR code within your device's cellular settings to install the eSIM profile. It is crucial to complete the installation in your home country while connected to Wi-Fi. Activate the data plan only upon arrival in Milan to maximize its validity period and connect to local networks like TIM or Vodafone.
