While Barcelona offers some public Wi-Fi (e.g., 'Barcelona Wi-Fi' network), it can be slow, unreliable, and less secure. An eSIM provides a private, consistently fast connection crucial for navigation, ride-sharing apps, and secure transactions, especially when you're out exploring Park Güell or Barceloneta beach. Don't rely solely on public Wi-Fi.
