Yes, your phone must be unlocked to use an eSIM in Barcelona. If your device is locked to a specific carrier, it won't be able to connect to the local Spanish networks (Movistar, Orange, Vodafone) that EastESIM utilizes. Confirm your phone's unlocked status before purchasing an eSIM to ensure seamless connectivity throughout your trip.
