Activating your CoreESIM for Berlin prior to landing at Berlin Brandenburg Airport (BER) is simple. After purchasing your eSIM plan, you'll receive a QR code or manual details via email. While still connected to Wi-Fi at home, navigate to your smartphone's cellular settings (e.g., iOS: Settings > Cellular > Add eSIM; Android: Settings > Network & Internet > SIMs > Download a SIM). Scan the QR code to install the profile. Ensure the profile is installed but not enabled until you arrive in Germany to ensure the plan's validity period commences at the correct time.
