Yes, your eSIMFlyer will generally provide strong 4G signal within the sheltered waters of the Bay of Gibraltar, perfect for capturing and sharing those incredible moments with wild dolphins. As the boat ventures further out into the open sea towards the Strait, the connection may become less consistent. Be sure to upload your best shots while you're still within the bay's reliable coverage zone!
