eSIM Antigua and Barbuda

Antigua is compact and fairly low-lying, so FLOW reaches the places most visitors spend their days. That means St John’s and the cruise piers at Heritage Quay and Redcliffe Quay, the hotel strip at Dickenson Bay and Runaway Bay, the west coast past Jolly Harbour to Ffryes and Darkwood beaches, and the yachting harbours at English Harbour and Falmouth. The hills of the south-west are patchier, especially on the rainforest section of Fig Tree Drive and the trail up Mount Obama. On the Atlantic side, Half Moon Bay and Devil’s Bridge can be weaker than the west coast. Barbuda is the real exception. Outside Codrington coverage is sparse, and the pink sand beaches or the frigate bird colony across the lagoon may leave you offline for a while.

Connects to FLOW over fast 4G/LTE. That’s the Cable & Wireless network, and the eSIM sticks to it on both islands. We don’t slow it down. On a hotel balcony at Dickenson Bay a video call usually works fine, while on the empty side of Barbuda it may be one bar, or none.

• 1–3 GB: a cruise day in St John’s, or a long weekend if you lean on the hotel Wi-Fi. Gigabytes are pricier here than in Europe, so a short stay rarely justifies more
• 5–10 GB: a week or two at a resort or on a charter, with video calls home and uploads from the beach
• 20 GB: a month on the island, a season working on a yacht in English Harbour, or a laptop running on hotspot

English Harbour comes first for most people. Nelson’s Dockyard there is a restored Georgian naval yard and a UNESCO World Heritage Site, and on Sunday evenings the party at Shirley Heights above it brings a steel band, a barbecue and the view over both harbours. In St John’s, browse Heritage Quay and the public market. Snorkel Cades Reef, or meet the rays at Stingray City. The Atlantic side has Devil’s Bridge, a sea arch, and the wide curve of Half Moon Bay, with the ruins of Betty’s Hope sugar estate inland. Barbuda, a ferry ride away, has the pink sand beach and the frigate birds of Codrington Lagoon.

Google Maps handles the roads well enough, but save Antigua offline before driving Fig Tree Drive or heading over to Barbuda. Traffic keeps left, and car hire desks arrange the temporary local driving permit you’ll need. Taxis aren’t metered, so confirm the fare before you get in. Minibuses leave from the bus stations in St John’s and cost little, though they thin out in the evening. Chartering a boat? Download your charts in Navionics or a similar app before you cast off. Restaurants, boat operators and villa managers mostly confirm things on WhatsApp. You can pay in Eastern Caribbean or US dollars almost anywhere.

On most European and UK plans Antigua falls into an expensive roaming zone, and many North American plans charge by the day. Install the eSIM at home. On landing, choose it for mobile data, switch its Data Roaming on, and leave roaming off on your usual SIM. Calls and SMS to your usual number still come through, including the airline’s check-in link.
