Yes, both Flow and Digicel have 4G in Codrington and along the main road to the ferry dock. Coverage drops sharply outside the village — 17-Mile Beach, the pink-sand coast, and most of the Frigate Bird Sanctuary lagoon have no signal. Download offline maps and any boat schedules before leaving Codrington.

Yes, 4G from both carriers reaches the Shirley Heights lookout and holds through the hike up from Nelson's Dockyard. During Sailing Week in April or the Charter Yacht Show in December, expect slower speeds when the event crowd peaks, but WhatsApp and basic browsing still work.

Budget 3–5 GB if you are using WhatsApp for crew coordination, streaming weather radar, and uploading a few photos each evening. Add another 2–3 GB if you plan to video-call home or livestream from anchorages. Most charter coordinators share itineraries and mooring updates via WhatsApp, so keep the eSIM active even on passage days.

Yes, WhatsApp voice and video calls work over the eSIM's data connection. Quality is solid in St. John's, English Harbour, and Falmouth Harbour. Expect occasional drops on the interior roads and none at all on Barbuda's remote beaches.

Yes, both Flow and Digicel cover Nelson's Dockyard, the museum, and the Copper and Lumber Store with strong 4G. Signal holds inside the historic buildings and out on the docks. During major sailing events, bandwidth thins but connectivity stays up.

Both carriers blanket St. John's with comparable 4G — Heritage Quay, Redcliffe Quay, the public market, and the cruise terminal all work well on either network. The eSIM hands off automatically to whichever is stronger at your location, so you do not need to pick one manually.

Both have 4G in Codrington village and patchy reach outside. Neither covers 17-Mile Beach or the deeper lagoon areas of the Frigate Bird Sanctuary. The automatic handoff means you will land on whichever carrier has signal at each spot, but for most of Barbuda's coastline that answer is neither.

No, Antigua and Barbuda has no Uber, Bolt, or local ride-hail service. Airport transfers and resort taxis dominate; most drivers coordinate pickups via WhatsApp or phone call, so keep your eSIM active for booking and real-time coordination.

Most marina and resort Wi-Fi portals require you to load a webpage to authenticate, which works fine over the eSIM's cellular connection. Once you are past the portal, you can switch to Wi-Fi and save eSIM data for when you are off the dock or away from the resort.

A local Flow or Digicel SIM costs roughly the same per gigabyte and runs on the same towers, but you will spend 20 minutes at the arrivals kiosk filling forms and waiting for activation. The eSIM is live before you land — scan the QR at home, toggle it on, done. If your phone supports eSIM, there is no practical reason to hunt for a physical card.

Devil's Bridge has 4G at the main geological viewpoint; the Donkey Sanctuary has signal at the visitor center and paddocks. The interior roads between the two sites drop to edge or nothing, so download your route and any tour details before leaving the coast.

Streaming live weather radar (Windy, PredictWind) uses roughly 10–20 MB per session if you refresh every few hours. Budget an extra 100–150 MB per week if you check conditions daily. Downloading GRIB files for offline use cuts that to nearly zero but requires setup before departure.

Yes, hotspot is enabled by default with no throttle or extra fee. If you are filling customs forms, downloading mooring permits, or uploading crew lists, the eSIM handles it the same as your phone's direct connection. Useful when marina Wi-Fi is slow or requires per-device login.

Yes, both south-coast resort areas have strong 4G from Flow and Digicel. Signal reaches the beach, the water-sports huts, and the resort pools. Expect brief congestion when cruise passengers flood the beach bars, but connectivity recovers quickly.

Signal drops within a few minutes of leaving the Antigua coast and stays dead until you approach Codrington. The crossing takes roughly 90 minutes; download any maps, schedules, or tour confirmations before boarding.
