Your DataESIM will maintain a strong 4G LTE signal on the beach at Hideaway Island, crucial for uploading high-resolution photos and videos before or after your dive. However, as expected, cellular signals do not propagate effectively through water. Once you submerge to access the underwater post office, data connectivity will cease. This is standard for all cellular services; plan to transmit data while above the surface.
