Can I expect EastESIM connectivity at Vanuatu's Underwater Post Office?

Updated April 22, 2026

You'll enjoy strong EastESIM signal on Hideaway Island beach, perfect for uploading photos of your unique waterproof postcards before you mail them. However, as you dive into the crystal-clear waters to reach the world-famous Underwater Post Office, your connection will naturally be lost. Once you resurface, your EastESIM will instantly reconnect, letting you share your extraordinary experience with friends and family.
