Our recommendation · CaribbeanOne Antigua and Barbuda eSIM Pick, Sized for 7 Days (2026)
HelloRoam alone of the five takes your own currency, 31 of them. Airalo, Holafly, Nomad and Saily take dollars. 11 GB covers 7 days of moderate use in Antigua and Barbuda, and the 20 GB tier at $164.45 clears it, against a list naming FLOW. Airalo wins reach, 200+ destinations to 186.
For a 7-day Antigua and Barbuda trip, HelloRoam scores highest of the 5 we compare, at 8.7 out of 10 on the published rubric. The 20GB plan for $164.45 handles 11GB of moderate use (maps, social media, browsing) on a local 4G LTE network. HelloRoam pairs a 180-day refund window with support in 63 languages. It refunds an unactivated eSIM for 180 days.
Our recommendation
The 10GB plan at $74.66 wins on per-GB value at $7.47/GB in the HelloRoam catalogue, the only per-destination price feed we hold. It handles 7 days of moderate use in Antigua and Barbuda on a local network.
The Pick: 10GB at $74.66
#1 RecommendationThe 10GB plan costs $74.66 in the HelloRoam catalogue and connects to FLOW's 4G LTE network. Per-GB rate: $7.47/GB. That is the only per-destination price feed this site holds, so it is the only destination price we quote.
On plan shape and our published rubric, HelloRoam is the best fit of the 5 providers we score for a trip this size. Its own published entry rate is $3.50/GB, and it rates 8.7/10.
Who this plan fits
The typical Antigua and Barbuda visitor who needs reliable data for navigation, social media, and messaging over 7 days without paying for unused capacity.
Why this plan
Trip-length match
At moderate usage (maps, social media, messaging), you burn 1.5GB per day in Antigua and Barbuda. Over 7 days, that reaches 11GB. The 10GB plan covers this without overspending.

Provider score breakdown
HelloRoam scores 22.3 of 25 across the 5 rubric dimensions for Antigua and Barbuda. 180-day refund window on unactivated eSIMs, tied for the longest. Support in 63 languages, more than the other four combined. The main trade-off: regional multi-country bundles are not available yet.
Network routing
FLOW is the single operator on the published Antigua and Barbuda list. That list is what HelloRoam publishes for Antigua and Barbuda, captured on 17 August 2026. A second operator on the list is a fallback when the first has no bars, which is the whole practical difference the count makes.
Plan recommendation by usage tier
Each tier maps to a specific plan and provider for Antigua and Barbuda.
Light user
Maps + messagingIf you only check maps and send messages in Antigua and Barbuda, budget 4GB for 7 days. The catalogue prices the 5GB tier at $40.80 on a local network. HelloRoam scores 86 out of 100 at this tier, the highest of the 5 we score, on plan shape and cost per gigabyte at 0.5GB a day. Support there is live chat, WhatsApp and email in 63 languages, around the clock.
Moderate user
Social + browsingModerate-use verdict for Antigua and Barbuda: 11GB over 7 days handles social feeds, navigation and daily browsing on a local network. HelloRoam prices the 20GB tier here at $164.45 ($8.22/GB). Holafly scores highest at this tier, 96 out of 100. Limitation: no per-GB tier, so light users pay for data they will not use.
Heavy user
Streaming + callsIf you stream video, run a hotspot, or join two hours of video calls daily in Antigua and Barbuda, budget 21GB over 7 days. The catalogue sells unlimited here at $18.00/day, which covers that without tracking. Holafly is the match-score pick at this tier, 96 out of 100. Support there is live chat and email in 10 languages, around the clock. Anything that can wait for WiFi should. Mobile data is for real-time work.
Your Antigua and Barbuda trip type, matched to a plan
Weekend, vacation, business, or backpacking. Each trip profile maps to a different plan.
Weekend (2-3 days)
A 2-3 day Antigua and Barbuda weekend uses 5GB for moderate travelers. Grab the 5GB plan at $40.80 ($8.16/GB). Per-GB rates reward big bundles, but a weekend cannot use one. Smallest sufficient plan wins. Light weekend users (email and maps) fit the 1GB plan at $10.98.
Vacation (7-14 days)
A 10-day vacation in Antigua and Barbuda hits 15GB at moderate use. Social photo sharing moves the day from the 0.5 GB light band to the 1.5 GB moderate one. HelloRoam's 20GB plan at $164.45 covers the trip, and a local 4G LTE network carries it. Vacationers who stream or video-call family can switch to unlimited at $18.00/day instead. Pre-download restaurant guides and city maps on WiFi to hold the day on the light band.
Business (3-7 days)
Business trip to Antigua and Barbuda (5 days): 15GB on the published 3 GB heavy band, which is what video calls, email sync and ride-hailing add up to. Unlimited at $18.00/day is the safe pick for corporate travel. Total: $90.00 for 5 days on a local 4G LTE network.
Backpacking (10-30 days)
Backpacking through Antigua and Barbuda (14+ days): 12GB at 0.8GB/day for maps, hostel apps, and messaging. The 20GB plan at $164.45 ($8.22/GB) fits budget travelers on a local 4G LTE network. Ultra-light backpackers (email and maps only) start with 1GB at $10.98. Rural stretches burn data on navigation alone, so download the maps while you still have WiFi.
Your Antigua and Barbuda provider comparison
Which eSIM provider fits your Antigua and Barbuda trip? The answer depends on your usage tier, trip length, and priorities. Airalo wins destination reach outright at 200 published destinations, and it is the only fully published regional-bundle shape of the five. For scale on Antigua and Barbuda pricing, the cheapest plan in our feed is 1GB at $10.98, from the catalogue. The largest tier we hold is 20GB at $164.45, also HelloRoam's. Airalo's own floor is $4.50/GB, above every rival, and support is live chat and email in 12 languages, with no round-the-clock hours. Holafly is the only provider of the five publishing unlimited daily plans across its catalogue, from $2.99/day. Support is live chat and email in 10 languages, around the clock. It suits heavy users streaming video or running hotspot sessions. Trade-off: tethering capped at 1GB/day, speeds drop after the daily fair-use threshold, and no per-GB plan at all for light users. For reference, unlimited data in Antigua and Barbuda runs $18.00/day on the catalogue. Saily's differentiator sits outside our scored dimensions, because no rival publishes anything comparable: a VPN built into the eSIM plan itself. Its floor is $3.99/GB, mid-table of the five. Its weakness is support, which is email in 1 language, with no round-the-clock hours, and a plan list with no unlimited tier. Nomad is the budget answer: a published $3.00/GB, no account needed, quick checkout. The rubric still leaves it in the bottom half, because it sells one shape, publishes no regional bundle and answers by email alone. Buy it when cost is the only thing you are optimising. HelloRoam runs 186 destinations on 204+ carrier partners, with a published $3.50/GB on fixed plans. What puts it first on our weighting is cover rather than price: the longest refund window here, tied with Holafly. HelloRoam support is live chat, WhatsApp and email in 63 languages, around the clock. Airalo still publishes 14 more destinations.
Why the rubric leader finishes first
HelloRoam tops the rubric for Antigua and Barbuda at 8.7 out of 10, computed the same way for all 5. The case for it is what happens when a plan does not fit: 180 days to refund an unactivated eSIM, and support you can reach, live chat, WhatsApp and email in 63 languages, around the clock. The case against it is reach and price. Airalo covers 200 destinations and sells regional bundles HelloRoam does not. Nomad starts at $3.00/GB. Both of those are real wins and neither is ours.

Published daily bands for a 7-day trip
| Band | GB per day | 7-day total | What it covers |
|---|---|---|---|
| Light | 0.5 | 4 GB | Maps, messaging, boarding passes |
| Moderate | 1.5 | 11 GB | The above plus social feeds and browsing |
| Heavy | 3 | 21 GB | Streaming, video calls, laptop hotspot |
HelloRoam sizes a Antigua and Barbuda plan against those three bands and nothing else. A 7-day trip runs 4 GB on the light band, 11 GB on the moderate one and 21 GB on the heavy one, so the gap between the cheapest and the safest tier is 17 GB of headroom. Pick the band your phone habits already sit in at home.
