Best eSIM for Antigua and Barbuda

Antigua has a third mobile network that most SIM guides still leave out, and it changes the maths. Alongside Flow and Digicel, the government utility APUA runs inet Mobile, a 4G LTE Advanced network that sells prepaid plans on physical SIM or eSIM, and in September 2026 it was advertising visitor plans with a complimentary SIM or eSIM through a booth at V.C. Bird International Airport. Its All In 10 plan is EC$44, about 16.30 US dollars at the fixed rate of 2.70, for 10 GB over seven days with 500 local minutes. Among the travel eSIMs, Nomad is cheapest at 19 dollars for 5 GB on Flow, while Airalo and Holafly both run on Digicel. None of the three uses inet.

The airport sits about 15 minutes by taxi from St John's and roughly 40 from English Harbour, so the arrival here is short and the case for landing with a plan already live is weaker than on islands with a long transfer. What an eSIM still buys you is certainty: no queue at a booth whose hours are not published, no ID check, and data the moment the jet bridge connects. Stays of a week or more, crews living aboard in Falmouth Harbour and anyone heading on to Barbuda should price the local plans first. The eSIM Finder will size a plan to your dates if you would rather skip the counter.

Quick Pick: the Best eSIM for Antigua and Barbuda

Nomad (Antigua and Barbuda 5 GB / 30 days): Nomad undercuts Airalo and Holafly at every size here: 5 GB for 19 dollars over thirty days on Flow, which covers a resort week with room for maps and photo uploads. For a week or longer, compare it with inet's EC$44 All In 10 before you pay.

Airalo Antigua and Barbuda Plans

Airalo's prices for Antigua and Barbuda barely move with validity. 1 GB for three days is 7.50 dollars. The 3 GB allowance runs 18.50 dollars over three days and 20 over a week. 5 GB costs 29 for seven days, 29.50 for fifteen and 30 for thirty. So the thirty-day 5 GB plan is only a dollar more than the seven-day one, and it is the only Airalo plan here worth buying unless you really need just a single gigabyte. At its best that is 6 dollars a gigabyte, well above Nomad's 3.80.

The reason to pick it anyway is Digicel. It is the network travellers tend to rate slightly ahead on consistency outside the main tourist areas, and it is the only one of the three with a store listed on Barbuda, in Codrington. If your week includes the east coast drives to Devil's Bridge and Half Moon Bay, or a night or two on Barbuda, that is a fair reason to pay a little more for the same 5 GB.

What Airalo does not offer here is size. Nothing goes above 5 GB, there is no unlimited plan, and a boat crew or heavy uploader will run through the allowance quickly. For those users, a Digicel Prime Ultra bundle bought at the Redcliffe Street store is the same network at a fraction of the price.

Holafly Antigua and Barbuda Plans

Holafly now prices Antigua and Barbuda by the day rather than in fixed bundles. One day costs 11.50 dollars, three days 19.90, five days 28.90, a week 36.50 and ten days 41.90. After that the curve steepens: two weeks is 64.50, fifteen days 68.90 and thirty days 111.90. The sweet spot is ten days, where each extra day past a week costs under 2 dollars.

It is aimed at a particular visitor. Someone flying in for Sailing Week to shoot and upload race footage from a chase boat, or a remote worker spending ten days in a villa above Jolly Harbour, gets unlimited data on Digicel without counting gigabytes. A three-night stopover at a Dickenson Bay all-inclusive, where the resort WiFi carries most of the load, does not need it, and a 7 dollar Nomad gigabyte does the job for a fraction of the price.

Against the local market, Holafly is expensive. A week at 36.50 dollars is more than twice inet's All In 10, and the monthly plan costs three times inet's All In 22. It is data only, so there is no number for a taxi dispatcher or a dive shop, and unlimited plans usually limit hotspot sharing, so check the terms if a laptop is involved.

Nomad Antigua and Barbuda Plans

Nomad's Antigua and Barbuda ladder reads 1 GB for seven days at 7 dollars, then 3 GB at 16, 5 GB at 19, 10 GB at 34 and 20 GB at 49, the last four each lasting thirty days. That makes it the cheapest travel eSIM for this country at every size, including the entry plan, where it undercuts Airalo's three-day gigabyte by 50 cents and lasts more than twice as long. The 5 GB plan at 3.80 dollars a gigabyte is the natural buy for a resort week with day trips to the Dockyard and Shirley Heights.

It connects to Flow, the older of the two big commercial operators. Reports from 2026 put Flow and Digicel close to level on Antigua, with Flow comfortable around St John's, the northern hotel strip and the west coast. Where Nomad is thinner is at the edges, on the Atlantic headlands and out on Barbuda's beaches, where either network can fade.

Read the product page with care. Besides the fixed-total plans, Nomad also lists daily-allowance plans for Antigua that slow to 512 kbps once the day's quota is spent and reset every 24 hours. For most visitors the fixed plan is the better deal. And be honest with yourself about length: once a stay passes a week, inet's EC$44 All In 10 carries twice the data of Nomad's 5 GB plan for less money.

Mobile Networks in Antigua and Barbuda

Three companies sell mobile service across the twin-island state. Flow is the former Cable and Wireless operation, traded as LIME until 2015 and now part of Liberty Latin America. Digicel arrived in the mid 2000s and today runs a store on the corner of Redcliffe Street and Market Street in St John's plus a branch in Codrington on Barbuda. The third is inet Mobile, the commercial brand of the Antigua Public Utilities Authority's telecoms unit, which also supplies the country's water and electricity. inet describes its network as 4G LTE Advanced with island-wide voice and data coverage, and it sells prepaid plans on either a physical card or an eSIM.

Older prepaid references still describe APUA's mobile arm as a 2G service with no data, and several travel guides published this year list only Flow and Digicel. Both are out of date. inet's own price sheet in September 2026 runs from a one-day All In plan with 2 GB up to a 30 GB monthly data bundle, and its FAQ confirms eSIM support. For a visitor that matters because inet is the only operator in the country advertising a plan built for visitors, and it is also the network no travel eSIM brand connects to.

Terrain is gentler than on the volcanic islands to the south. Antigua's highest point, Mount Obama in the south-west, is a little over 400 metres, and most signal complaints come from the far ends of the island rather than from valleys: the eastern headlands out toward Devil's Bridge and Half Moon Bay, the rainforest stretch of Fig Tree Drive, and the coves you reach only by boat. Barbuda, about 40 kilometres to the north, is flat and thinly populated. Digicel keeps a staffed store in Codrington, which is a reasonable sign of service in the village, but coverage out on the long beaches and around the lagoon is thinner, so download maps before the ferry leaves.

None of the three operators has launched commercial 5G. Plan around 4G LTE, which is ample for navigation, video calls and uploading a day's photos from the Dockyard.

How to Choose the Right Plan

Decide first whether you will spend more than a week here. For a short stay at a Dickenson Bay or Jolly Harbour resort, Nomad at 19 dollars for 5 GB over thirty days is the simplest buy, and its 7 dollar gigabyte is enough for a two-night stopover. If your plans lean toward the east coast, the south-west hills or a night on Barbuda, Airalo puts you on Digicel, and its thirty-day 5 GB plan at 30 dollars is the only one of its six worth choosing. Holafly earns its price for a heavy user on a stay of up to about ten days, such as a Sailing Week visitor uploading footage every evening. For anything longer, or for yacht crews based at Nelson's Dockyard or Falmouth Harbour, the local plans win clearly: inet's All In 10 is EC$44 for 10 GB over a week and its All In 22 is EC$100 for 22 GB over a month, and Digicel's Prime Ultra bundles from the Redcliffe Street store are close behind. inet also sells on eSIM, so an eSIM-only phone is no barrier to buying local. The sensible hybrid is a small travel eSIM for landing day, then a local plan from St John's once you know how much data the trip really needs.

Frequently Asked Questions

Is it true that Antigua's government utility sells a visitor SIM with a free eSIM?

Yes, as of September 2026. inet Mobile, run by the Antigua Public Utilities Authority, advertises three visitor plans that each include a complimentary SIM or eSIM: 7 days with 10 GB and 500 local minutes for US$16, 14 days with 16 GB for US$31, and 30 days with 22 GB for US$37. You need government photo ID, and you can sign up by email, at the inet booth at V.C. Bird International Airport or at an inet branch. The plans are promoted around the Commonwealth summit the country hosts this year, so confirm they are still on sale before you rely on them.

Which is cheaper for a week in Antigua, a travel eSIM or a local plan?

The local plan, by roughly half. inet's All In 10 costs EC$44, about 16.30 US dollars, for 10 GB over seven days, and Digicel's 7 Day Prime Ultra costs EC$48, about 17.80 dollars, for 8.5 GB plus unlimited local calls. Nomad, the cheapest travel eSIM here, charges 34 dollars for 10 GB or 19 for 5 GB. The eSIM wins on convenience rather than price: nothing to queue for, no ID, and data working before you leave the plane.

Will my Antigua eSIM work on a day trip to Barbuda?

Yes. Barbuda is part of the same country, so every Antigua and Barbuda plan from Airalo, Nomad and Holafly covers it. Coverage is the limit rather than the plan: expect service around Codrington and patchy or no signal out on the beaches and the lagoon. The Sea Bridge Ferries crossing, formerly the Barbuda Express, takes about 90 minutes and runs daily, with one-way adult fares from US$65, and small planes and helicopters make the hop from V.C. Bird in minutes.

I am crewing a yacht out of Falmouth Harbour for a month. What should I buy?

A local monthly plan. inet's All In 22 is EC$100, about 37 US dollars, for 22 GB and 1,200 local minutes over thirty days, and its Big Data 30 GB bundle is EC$192.28. Digicel's 30 Day Prime Ultra is EC$132 for 20 GB of general data plus a large entertainment allowance and unlimited local calls. The biggest travel eSIM, Nomad's 20 GB, is 49 dollars. A local number also lets the marina office, provisioning suppliers and delivery drivers call you back.

Do any of the travel eSIMs cover Antigua and the next island on a charter?

The single-country plans do not. Montserrat, St Kitts and Guadeloupe each need their own coverage. Regional Caribbean plans from all three brands include Antigua and Barbuda, and our guide to an eSIM for Caribbean island hopping compares them against buying one country at a time. For a charter that stays inside Antigua and Barbuda waters, the single-country plan is enough.

Can I pay for a local SIM in US dollars?

Usually, and inet quotes its visitor plans in both currencies. Everything else is priced in East Caribbean dollars, which have been fixed at 2.70 to the US dollar since 1976. V.C. Bird has no money exchange counter according to the airport's own FAQ, so carry a card or some US notes if you plan to buy at the arrivals booth, and draw EC dollars from an ATM in St John's for store purchases.
