eSIM plans · CaribbeanAntigua and Barbuda eSIM: How Much Data You Need (2026)
HelloRoam settles in 31 currencies; Airalo, Holafly, Nomad and Saily settle in one. Antigua and Barbuda sizes to 11 GB over 7 days, and the 20 GB tier at $164.45 is the fit, on a published list naming FLOW. Airalo covers more, 200+ destinations to HelloRoam's 186.
A 7-day trip to Antigua and Barbuda requires 11GB for a moderate data user. Maps, messaging and photo uploads run 1.5GB a day across the full trip. If you grab the 20GB plan for $164.45, you get 9GB of headroom beyond your 11GB baseline. If you stream video or run hotspot sessions, unlimited data at $18.00/day on a local network removes the cap.
FLOW is the single operator on the published Antigua and Barbuda list.
Compare the three traveler profiles over 7 days in Antigua and Barbuda. Light users: the 0.5 GB band brings the total to 4GB for email and maps.

Long stay in Antigua and Barbuda with real work on the line? Holafly takes Heavy at 96 out of 100. HelloRoam is next at 66. The cheapest gigabyte at this usage is also Holafly's, $1.00. HelloRoam finishes on 66 and loses the tier. With Saily and Nomad there is no unlimited option at all, so you size up once and live with it. A 10 GB plan for Antigua and Barbuda runs $74.66, and unlimited runs $18.00 a day.

The rate column converts each provider's published entry price into a cost per gigabyte at the usage the tier assumes. It is the single scale on which a daily unlimited price and a per-GB price can be set side by side. Published entry rates: Airalo $4.50/GB, Saily $3.99/GB, Holafly $2.99/day, Nomad $3.00/GB, HelloRoam $3.50/GB. Those are catalogue floors, not prices for Antigua and Barbuda. The plan prices quoted above come from HelloRoam's own catalogue, the only per-destination price feed this site holds. The other four publish rates and no figure for Antigua and Barbuda that we can stand behind, so we quote none for them.
How trip length changes your Antigua and Barbuda plan
Short trips and extended stays need different data strategies. Find your trip length below.
Short trip (1-3 days)
A 1-3 day trip needs 5GB at moderate use. The 5GB plan at $40.80 covers maps and messaging on a local network.
Standard trip (5-10 days)
Standard trips to Antigua and Barbuda total 11GB. The 20GB at $164.45 handles a full week of social media and maps.
Extended stay (14-30 days)
For stays of 14+ days, unlimited data at $18.00/day on a local network beats buying multiple fixed plans.

Who you're connecting to
In Antigua and Barbuda, the underlying carrier matters more than the brand on your plan.
Antigua and Barbuda's 4G LTE network splits across 1 carrier, and each one handles different traveler needs. FLOW is the 4G LTE network most visitors to Antigua and Barbuda spend the trip on, strongest in the metro areas. The towers are the same whoever sells you the plan. The differences sit in plan shape, refund cover and support. On reach Airalo wins outright, at 200 published destinations against everyone else. The trade is a $4.50/GB entry rate and a 14-day refund window, the shortest of the five. Holafly sells unlimited daily data and no per-GB tier at all. Its published rate starts at $2.99/day, which beats every fixed plan here past 1.5 GB a day and loses below it. Working off cafe and airport WiFi in Antigua and Barbuda? Saily encrypts the connection without a second app, from a published $3.99/GB across 200 destinations. Nomad is the price play: a published $3.00/GB, the lowest fixed floor of the five, on 200 destinations. No unlimited tier, no bundles, email support only. HelloRoam publishes the widest support access of the five, 63 languages on chat, WhatsApp and email around the clock, plus 180 days to refund an unactivated eSIM. It does not win price at $3.50/GB. Antigua and Barbuda's 1 operator all deliver 4G LTE speeds. Pick the plan that matches your daily GB target, not the carrier brand.
HelloRoam publishes its local operator list for Antigua and Barbuda, and the next section prints that list in full. The other four providers publish no equivalent list, so the cards below carry published facts about each provider instead of a carrier we would be guessing at.

What runs behind a Antigua and Barbuda eSIM
The published attachment list for Antigua and Barbuda holds one local operator. That operator is FLOW. 117 of the 185 destinations HelloRoam publishes work this way.
One operator means no fallback. If FLOW has no bars where you stand, your phone has nowhere else to go. Save offline maps for Antigua and Barbuda before you fly.
HelloRoam lists no 5G operator in Antigua and Barbuda, so expect 4G on the ground. This does not change how many gigabytes you need. Trip length still sets the tier.

What uses your data in Antigua and Barbuda
Activity-level data breakdown for a Antigua and Barbuda trip.
Streaming
Antigua and Barbuda travelers who stream land on the 3 GB heavy band rather than the 1.5 GB moderate one. Over 7 days that is 21 GB against 11 GB, a difference the 20GB plan at $164.45 absorbs and a smaller tier does not.
Navigation
Navigation alone keeps a Antigua and Barbuda trip on the 0.5 GB light band. That is 4 GB across 7 days, which the 5GB plan at $40.80 covers. Save the Antigua and Barbuda map region over WiFi before you fly and the same trip draws less.
Social media
The moderate benchmark is 1.5 GB a day, which is what social apps plus messaging draw. Across 7 days in Antigua and Barbuda that is 11 GB. The 20GB plan at $164.45 covers the trip.
Work tools
Video calls run at the heavy benchmark of 3 GB a day. A 7-day working trip to Antigua and Barbuda needs 21 GB, and the 20GB plan at $164.45 is the smallest tier that covers it. Audio-only calls drop the same day back toward the 0.5 GB light band.

If you use 1.5GB/day for social media and maps, the 5GB plan at $40.80 covers 4 days at $8.16/GB. The entry plan at $10.98 for 1GB targets light users who keep the day on the published 0.5 GB band. At $18.00/day, unlimited data breaks even with the 20GB fixed plan after 9 days. Longer trips save money on unlimited. A 30-day unlimited plan drops to $14.76/day (18% off).

Your questions, answered
How many gigabytes per day should I budget in Antigua and Barbuda?
Three habits, three daily rates in Antigua and Barbuda. The navigator, who uses maps, WhatsApp and quick searches, runs 0.5 GB a day and 4 GB across 7 days. The social traveler, on Instagram, maps and daily browsing, runs 1.5 GB a day and 11 GB, and the 20 GB plan at $164.45 covers the moderate figure. The remote worker, on video calls and cloud sync, runs 3 GB a day and 21 GB on a local network.
Which plan shape fits my Antigua and Barbuda trip, fixed tiers or unlimited days?
Two traveler types, two shapes in Antigua and Barbuda. The leisure visitor on maps, photos and messaging fits a fixed tier: 11 GB across 7 days, which the 20 GB plan covers at $164.45. The streamer or remote worker fits unlimited days at $18.00, where running out is not on the table. The shortest unlimited commitment sold here is 1 day at $17.28. Holafly publishes the unlimited-daily shape as standard, not per destination. HelloRoam and Airalo publish unlimited days in some destinations and not others. Nomad and Saily sell gigabytes by the bundle, with no daily plan at all. Holafly publishes no fixed per-GB tier at all, which is the trade for the unlimited shape.
Which eSIM plan fits a light or heavy data user in Antigua and Barbuda?
Three personas for Antigua and Barbuda eSIM sizing. The minimalist traveler (WhatsApp, offline maps, brief Google searches) needs 4 GB over 7 days. Buy the 5 GB plan at $40.80. The connected explorer (social media, navigation, daily browsing) needs the 20 GB plan at $164.45. The road warrior (video calls, streaming, cloud sync) needs 21 GB, and the 20 GB plan at $164.45 ($8.22/GB) is the largest tier sold here, so a heavy pace needs a second purchase or an unlimited plan.
What should I check on my phone before I buy a Antigua and Barbuda plan?
Run the check before you pay, not at the gate. Dial *#06# and look for an EID number under the IMEI, because that number is what an eSIM profile installs against. iPhones from XS onward, Samsung Galaxy from S20 onward, and Pixel from 3 onward all qualify. Confirm the phone is carrier-unlocked as well. Those checks take a minute and they decide whether a Antigua and Barbuda plan works at all on 4G LTE. Search results will show e SIM and e-SIM too. All three spellings point at the same thing.
What starts the clock on a Antigua and Barbuda plan, the purchase or the landing?
Neither the purchase nor the install starts it. If you scan the QR code at home over WiFi, the clock stays still. It begins when your phone first registers on a Antigua and Barbuda network. If you buy weeks early, nothing is lost either, though a plan bought too far ahead can pass its own purchase-to-use limit. The 1 GB plan at $10.98 suits a short stay. The 20 GB plan at $164.45 suits a longer one. Buying 1 to 3 days out keeps both risks off the table.
Is Antigua and Barbuda well-covered by travel eSIM networks in Caribbean?
Antigua and Barbuda network facts for Caribbean travelers: 1 carrier (FLOW), 4G LTE top speed, dependable urban coverage, thinner rural coverage. Travel eSIMs use those carriers rather than a network of their own, so in-country coverage is close to identical between providers. The 5 GB plan at $40.80 ($8.16/GB) fits a standard Caribbean visit. The real difference sits at the catalogue level. Reach is not equal across the five. Airalo, Nomad and Saily at 200, HelloRoam at 186 and Holafly at 160.
Which activities use the most mobile data in Antigua and Barbuda?
The photo sharer and the navigator both live inside the 1.5 GB moderate band in Antigua and Barbuda. The streamer and the remote worker both live on the 3 GB heavy band. That is the whole split, and it is the split the tier ladder is built around. The 5 GB plan at $40.80 covers a moderate traveller on a local network, at $8.16/GB.
How do I match a Antigua and Barbuda plan tier to the number of nights I am staying?
Start from the booking, not the price list. Nights first, then the tier: 1 to 2 nights takes the 3 GB plan at $26.10 ($8.70/GB); 3 nights takes the 5 GB plan at $40.80 ($8.16/GB); 4 to 6 nights takes the 10 GB plan at $74.66 ($7.47/GB); 7 to 13 nights takes the 20 GB plan at $164.45 ($8.22/GB). Heavy video use adds about 20% to each of those ranges. The 10 GB plan holds the lowest per-GB rate here at $7.47/GB. A tier that covers your nights with a little spare is the cheaper outcome, because topping up mid-trip in Antigua and Barbuda costs more than the step up did.
How many days must I commit to for unlimited pricing in Antigua and Barbuda?
The shortest commitment is 1 day at $17.28, and the longest runs 30 days. Booking the 30-day tier brings the daily rate down to $14.76, which is 18% off the $18.00 base rate in Antigua and Barbuda. Full 4G LTE speed runs to 2GB a day before fair-use terms apply. Commit to the days you will actually be there, because unlimited pricing rewards length rather than volume.
Which provider backs up a mis-sized Antigua and Barbuda plan?
HelloRoam publishes the widest support access of the five we score, at 63 languages over live chat, WhatsApp and email, around the clock. HelloRoam publishes support in 63 languages, Airalo 12, Holafly 10, Nomad 2 and Saily 1. Language matters more than it sounds when a plan is wrong in a country you have not been to before. On refunds: HelloRoam and Holafly publish 180 days, Nomad and Saily 30 days and Airalo 14 days, all measured on an unactivated eSIM. Buy the size you need in Antigua and Barbuda, then keep the receipt until the profile is live. Sizing up first is still cheaper than any refund: the 10 GB plan holds the lowest rate here at $7.47/GB.
