How reliable is eSIMAdventures connectivity near Buck Island Reef National Monument in the USVI?

Updated April 22, 2026

When exploring the waters around Buck Island Reef National Monument, especially during the boat ride from Christiansted, you'll generally find decent signal. However, once you're actively snorkeling or diving around the actual reef, be prepared for connectivity to become spotty or even disappear. Our eSIMAdventures plans are designed to keep you connected where it matters most, but underwater exploration is a different beast!
