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.
An Antigua and Barbuda SIM card from HelloRoam covers both islands under one plan from £7.55 on FLOW 4G networks. A physical Antigua and Barbuda SIM card bought locally at the airport only covers the main island network and often has no English-language support team if something goes wrong during your holiday.

Cat
On a trip to Europe, my hotel Wi-Fi was so slow and outside Wi-Fi was unreliable. I couldn’t take it anymore so I got helloroam for a few days. It was tricky to set up correctly because of the primary settings (with my original number). But I reached out to their customer service via WhatsApp. Super responsive and helpful, with specific and clear steps to troubleshoot. Appreciate having 4G roaming instead of being stuck with in and out Wi-Fi during my trip!!
Rated 5 out of 5 by this reviewer
Very good experience! The eSIM was easy to set up and worked great in London. It was much cheaper than it would have been to use my own operator there.
