Setting up your Truly Roaming eSIM for Barcelona is straightforward and best done before you even depart. After purchasing your plan, you'll receive a clear QR code via email. Simply go to your phone's cellular settings, select 'Add eSIM' or 'Add Cellular Plan', and scan the QR code. The eSIM profile will install onto your device. You can then ensure it's toggled on and ready to activate upon arrival in Spain. This guarantees you're connected for maps and communication the moment you step off the plane at Barcelona-El Prat (BCN).
