HelloRoam sells eSIM plans for Antigua and Barbuda. which prices 6 FLOW 4G plans from $10.13 for 1 GB over 7 days to $68.52 for 10 GB, a rate of $6.85 per GB. HelloRoam adds data to a live eSIM by top-up on 1,124 of its 1,129 plans with no new QR code, where Airalo lists 200 destinations.

All 6 HelloRoam Antigua and Barbuda plans sit on FLOW, which is why the coverage picture is one network rather than two: FLOW runs 4G across Antigua, English Harbour, Dickenson Bay, Jolly Beach and the resort strip included, and drops to 3G around Codrington on Barbuda. Digicel is the second operator on Antigua and is not sold through international eSIM providers. Remote northern Barbuda sits off-network.
