Does the DataESIM eSIM function at the Jacques Cousteau Underwater Reserve?

DataESIM provides strong 4G LTE signal on the surface, extending to Malendure Beach and aboard vessels operating in the Jacques Cousteau Underwater Reserve. This allows for pre-dive research, communication, and immediate post-dive data uploads. However, once you submerge for diving or snorkeling around the Pigeon Islands, the physical properties of water will naturally impede radio frequency transmission, resulting in a loss of cellular connection. Surface connectivity remains robust for all your digital needs.
