Compare eSIM plans for Antigua & Barbuda

Two mobile operators serve the country, Flow, the Cable & Wireless subsidiary, and Digicel, with 4G coverage that tracks population and tourism closely (sources: Internet Society Pulse, ITU DataHub). On Antigua, connectivity is rarely something you think about. On Barbuda, less populated and still rebuilding from Hurricane Irma, the infrastructure is thinner on the ground. And since much of a trip here happens on the water, the deciding factor is often your distance from shore rather than the quality of the land network.

• ●On Antigua, the network is dependable in St John's, along the north-west coast at Dickenson Bay, around Nelson's Dockyard and English Harbour, and up at the Shirley Heights lookout. It holds reasonably towards Devil's Bridge in the east and Half Moon Bay in the south-east, with dips in the inland gullies and around Betty's Hope, the old sugar estate.
• ●On Barbuda, expect signal around Codrington and on the approaches to the frigate bird sanctuary, then genuinely broken coverage along the pink sand beach and across the remoter stretches. The ferry run from Antigua crosses water where the signal drops out for spells, so download what you need before boarding.
• ●For sailing and catamaran days, remember a mobile network reaches a few miles offshore at best, depending on terrain and mast. Marine forecasts, mooring bookings and schedules are things to check at the dock. An eSIM replaces neither a VHF radio nor routing downloaded in advance.
