For a seamless eSIMAdventures experience in Barcelona, your smartphone must be unlocked. This means it's not tied to a specific carrier from your home country. If your device is locked, it won't be able to connect to the strong local Spanish networks such as Movistar or Vodafone that eSIMAdventures utilizes to keep you connected on urban explorations or mountain treks. Always confirm your phone's unlocked status before purchasing your eSIM to ensure uninterrupted connectivity from the moment you land.
