Is activating eSIM Wings in Spain more convenient than purchasing a local SIM at Madrid or Barcelona Airport, and is ID required?

Choosing eSIM Wings for your Spanish journey is undeniably simpler than the traditional airport SIM card hunt. Imagine landing at Madrid (MAD) or Barcelona (BCN), skipping the bustling kiosks, avoiding long queues, and sidestepping the mandatory passport registration process that EU law requires for physical SIM purchases. With eSIM Wings, you activate your data plan digitally, often before you even leave home. There's no physical card, no forms to fill out, and no ID checks. It's instant connectivity, allowing you to wander freely and explore Spain's vibrant culture from the moment you touch down.
