You will experience strong 4G signal with eSIM ProZone on vessels and at Malendure Beach, which serves as the entry point to the reserve. However, as expected, data connectivity will cease once you are submerged for diving or snorkeling activities around the Pigeon Islands. Our service focuses on surface and terrestrial connectivity.
