Generally, you will experience strong 4G signal within the sheltered waters of the Bay of Gibraltar during dolphin watching tours. Your WorldESIM will enable you to capture and instantly share those incredible moments of wild dolphins swimming alongside your boat. However, as the vessel ventures further out into the open waters of the Strait, the signal strength may naturally decrease. It's always best to enjoy the marine life firsthand and share your media when you're closer to shore.
