Antigua and Barbuda eSIM plansBuy online, install in one tap, land connected · 2026
Most visitors land at V.C. Bird International Airport, a short taxi ride from St. John's. Fares are fixed by route rather than metered, so travelers check rates on their phones and confirm pickups over WhatsApp. From there, data does the daily work: mapping the drive to Nelson's Dockyard, checking Barbuda ferry times, and sending that first harbor photo home. Antigua famously claims a beach for every day of the year, and finding the right one takes a working map.
