Activating your eSIMFlyer plan is straightforward, designed for travelers on the go. After purchasing, you'll receive a QR code via email. We advise scanning this code through your phone's settings (usually under 'Cellular' or 'Mobile Data' > 'Add eSIM') while you still have a Wi-Fi connection – ideally before you even leave home or during a layover. The eSIM profile installs instantly. Your plan's data validity only begins when it connects to a local network at your destination, ensuring you're online the moment you land, whether in Frankfurt or Singapore.
