Your eSIM Scout connection will be robust on the surface at Hideaway Island, enabling immediate uploads of your waterproof postcards and dive preparations. However, once you submerge to reach the underwater mailbox, expect a natural signal loss. Surface for transmission, dive for the experience – our priority is keeping you connected where it counts, ensuring you can share your unique Vanuatu adventures before and after your dip.
