Absolutely! It's highly recommended to configure your Truly Roaming eSIM before you even depart for London Heathrow (LHR) or Gatwick (LGW). You'll receive a QR code via email; simply scan it to install the eSIM profile on your device. This proactive setup ensures you have immediate, day-one connectivity the moment your plane lands, allowing you to instantly access maps, communicate with your team, or order transport to your accommodation in Covent Garden without any delay or searching for Wi-Fi.
