Not sure which plan to pick? Here's what we recommend based on your travel style:
English Harbour is a world-class sailing hub — you'll want data for weather apps, marina bookings, and charts. A 5–10 GB plan with 7–30 day validity works well for sailing stays of varying lengths.

Nelson's Dockyard, Shirley Heights, and Betty's Hope all benefit from having data for guided tours, Google Maps navigation, and uploading photos. A 3 GB plan for 5–7 days is well-suited for sightseeing itineraries.
