Is an eSIM Better Than an Antigua SIM card for UK Caribbean Holiday-Makers?
HelloRoam costs from £7.55 and beats buying a SIM card for Antigua at V.C. Bird Airport on both price and convenience. Airport SIM stalls in Antigua typically add a tourist premium, require passport details, and give no English-language data dashboard. A HelloRoam plan activates at home before your Gatwick or Manchester charter and connects to FLOW 4G the moment you land. Based on V.C. Bird Airport listings. Verified May 2026.
An Antigua prepaid SIM card bought at the airport is slower and costlier than a HelloRoam QR activation done before your flight. HelloRoam delivers an Antigua prepaid SIM card equivalent digitally to your inbox. No physical card, no counter wait, and no language frustration at arrivals after a seven-hour Gatwick transatlantic.
