How reliable is WorldESIM coverage at Buck Island Reef National Monument in the USVI?

When exploring the pristine waters around Buck Island Reef National Monument in the USVI, WorldESIM generally provides connectivity as you depart from Christiansted. However, given the nature of marine environments and underwater activities like snorkeling at the reef itself, signal strength can become weak or even non-existent once you are in the immediate vicinity of the reef or submerged. For optimal planning, consider downloading maps or information beforehand.
