We recommend activating your Truly Roaming eSIM for Spain before you even depart. Scanning the QR code and completing the setup while you still have a stable home internet connection ensures day-one readiness. This way, the moment you land at Barcelona-El Prat Airport (BCN) or Madrid-Barajas (MAD), your device will connect seamlessly to Movistar or Vodafone, providing immediate access for navigation, communication, and urgent work tasks without scrambling for airport Wi-Fi.
