While you can purchase physical SIMs at Madrid-Barajas Airport (MAD), it's highly recommended to buy and activate your Cellesim eSIM before you depart. This ensures you have immediate mobile data upon landing, allowing you to easily order a ride, navigate to your accommodation in neighborhoods like Malasaña, or check directions without relying on potentially slow airport Wi-Fi.
