Connectivity with eSIM ProZone is robust at the Marigot and Grand Case ferry terminals. However, during the open-water crossing to Anguilla, particularly away from the coastlines, you should anticipate a temporary reduction to 3G speeds or intermittent signal loss. We recommend completing any critical data tasks before departure or upon arrival at your destination.
