On the live Antigua-and-Barbuda-country ladder, the eligible 10 GB 30-day dest totals this pass are Nomad $34, Sim Local $44.50, GigSky $54.99 and Yesim $63.46. Dest has no Antigua-and-Barbuda-country 50 GB SKU; the printed dest 50 GB cheapest-at-size row is Ubigi Best World 50 GB 180-day at $99, so the 180-day out rule stays quiet and GigSky ranks third. Ubigi, Airalo and Saily publish no Antigua-and-Barbuda-country 10 GB 30-day SKU on dest (Ubigi Caribbean/World only; Airalo Antigua and Barbuda capped at 5 GB 30-day; Saily Antigua And Barbuda 1 GB 7-day plus Caribbean Islands regional). Roamless, aloSIM and ByteSim publish no Antigua-and-Barbuda-country SKU on dest. None of the four eligible 10 GB totals meet, so named-host tiebreak stays unused. Fifth and sixth stay empty.

Opensignal publishes no dedicated Antigua and Barbuda Mobile Network Experience operator report this pass. Opensignal's Global Network Excellence Index table retrieved this pass does not list Antigua and Barbuda as a reportable country row, so there is no GNEI overall / Availability / Excellent Consistent Quality / Download Speed cite for Antigua and Barbuda. Do not invent Opensignal awards for Flow, Digicel or APUA on this corridor.

DataReportal Digital 2026: Antigua And Barbuda (GSMA Intelligence figures) records 203 thousand cellular mobile connections active in Antigua and Barbuda in late 2025, equivalent to 216 per cent of the population, up 1,293 (+0.6 per cent) from end-2024, with 95.7 per cent of connections counted as broadband (3G/4G/5G). Those connection totals are market structure. They do not name a host for any pick.

ABS TV Radio on 18 June 2026 reported that Cabinet had confirmed local number portability was expected to take effect the following month, letting mobile users switch between Flow, Digicel and APUA INET while keeping their numbers under legislation first outlined in 2018. Number-portability coverage in the press is market structure, not a shop host string.

Antigua and Barbuda is not an EU member state and is not in the EEA. European Commission roam-like-at-home does not cover a visit on an Antigua-and-Barbuda-country travel eSIM. A prepaid Antigua-and-Barbuda-country travel eSIM is priced on the storefront's own terms. Do not invent RLAH for this corridor.

Barbuda-only coverage, Codrington, Montserrat, St Kitts, Guadeloupe and other Caribbean islands stay empty as coverage claims unless that shop names the place. No ranked shop named those places as separate coverage on an Antigua-and-Barbuda-country SKU this pass. The country product label is Antigua and Barbuda on the ranked shops; that is the country name, not a Barbuda-only latch. Nomad prints an overseas-territory hedge. Yesim names Saint John's on its city list. Sim Local ESFX-0048-SL1 coverage is Antigua & Barbuda with a generic rural hedge. Do not invent a Caribbean island-hop latch from Flow, Digicel or C & W presence alone.

The dest 10 GB, 30-day country order among the four ranked picks is Nomad, Sim Local, GigSky, Yesim. Once a plan registers on an Antiguan network, top-ups stay inside that provider's app.

St John's stay length plus a daily data budget for English Harbour sailing days or beach runs sets the size before the four ranked Antigua-and-Barbuda-country rows. Plan Match at /plan-match handles that sizing on this page when the GB figure is still open.

CodeDest prints ATESIM 20% on the 10 GB row. Programme excludes sale, unlimited, Thailand 50 GB, plans under USD 5

Nomad's Antigua and Barbuda shop names Network for Antigua and Barbuda: FLOW. The 10 GB 30-day SKU (Antigua and Barbuda_10GB_30Day) lists FLOW on mask_network with coverage AG (mccmnc 344920_AG, types 4G). The same shop FAQ prints: Yes, Nomad's eSIMs support tethering / hotspot. Coverage may not include overseas territories. Barbuda-only, Codrington, Montserrat, St Kitts and Guadeloupe are not on that shop as separate coverage claims. Do not treat the FLOW catalogue line as coverage for neighbouring Caribbean islands.

Live-table 10 GB 30-day is $34, ATESIM 20% where the dest table prints it. That $34 total is the cheapest ranked 10 GB country floor and dest cheapest at 10 GB. ATESIM 20% does not apply to unlimited, add-ons, business, sale, Thailand 50 GB, or plans under USD 5. The Antigua and Barbuda 10 GB 30-day shop offer sits above the USD 5 floor. Live-table 3 GB 30-day is $16 ATESIM, which is dest cheapest at 3 GB among Antigua-and-Barbuda-country rows. Live-table 5 GB 30-day is $19 ATESIM, the dest Antigua-and-Barbuda-country cheapest at 5 GB. Live-table 20 GB 30-day is $49 ATESIM, the dest Antigua-and-Barbuda-country cheapest at 20 GB. No dest 25 GB, 50 GB or 30-day unlimited Antigua-and-Barbuda-country row for Nomad this pass. Shorter dest rows include 1 GB / 7 days at $7 ATESIM.

Strengths

+Cheapest ranked 10 GB 30-day dest total ($34)
+Dest cheapest 3 GB, 5 GB, 10 GB and 20 GB 30-day country rows ($16 / $19 / $34 / $49)
+Shop names FLOW; 10 GB SKU mask_network names FLOW (344920_AG)

Limitations

−No dest 25 GB, 50 GB or unlimited 30-day country row
−Overseas-territory hedge only; neighbouring islands and Barbuda-only unnamed as coverage
−No cheapest-at-size win at 1 GB on the 30-day ladder (Yesim holds 1 GB)
−Ladder stops at 20 GB among country capped rows

Verdict · Nomad wins the ranked 10 GB floor at $34 with FLOW on the shop and 344920_AG on the 10 GB mask, and the same Local ladder also holds the 3 GB, 5 GB and 20 GB country floors at $16, $19 and $49.

HotspotYes on those SKUs

CodeATESIM 10% on the dest row

Sim Local's Antigua & Barbuda 10 GB / 30 days SKU (ESFX-0048-SL1) prints Networks Flow. Hotspot and tethering: Yes. Coverage is Antigua & Barbuda on that SKU. The same SKU coverage copy expects strong coverage in major cities and urban areas and notes that remote, rural or less populated regions such as mountains, deserts or countryside may see variable signal and speeds. Barbuda-only, Codrington, Montserrat, St Kitts and Guadeloupe stay unnamed as coverage claims. Do not treat Flow alone as proof of neighbouring-island coverage.

Live-table 10 GB 30-day is $44.50, ATESIM 10% where the dest table prints it. Live-table 5 GB 30-day is $25.75 ATESIM, behind Nomad $19. Live-table 20 GB 30-day is $74.25 ATESIM, behind Nomad $49. No dest 25 GB, 50 GB or 30-day unlimited Antigua-and-Barbuda-country row for Sim Local this pass. Shorter dest rows include 1 GB / 3 days at $7.50 ATESIM and 3 GB / 7 days at $17 ATESIM. Dest Sim Local regional comparison block prints Antigua and Barbuda only $74.25 / North America $35 / Global $35 for a 20 GB label with ATESIM; country is dearer than North America and Global on that printed block (Engineering flag on dest prose).

Strengths

Verdict · ESFX-0048-SL1 is second at $44.50, names Flow with hotspot yes, and its 20 GB country total ($74.25) trails Nomad $49 and the dest North America / Global $35 comparison rows.

CodeATESIM 15% on the dest row

GigSky's Antigua and Barbuda shop retrieved this pass does not name Flow, Digicel or APUA as host, so the MNO host is unpublished. HotspotBody: Unlimited use included. Barbuda-only, Codrington, Montserrat, St Kitts and Guadeloupe stay unnamed as coverage claims on that shop. Dest has no GigSky Antigua-and-Barbuda-country 50 GB SKU at any duration, so the 180-day out rule does not remove GigSky; the 10 GB total alone puts it third.

Live-table 10 GB 30-day is $54.99, ATESIM 15% where the dest table prints it. Live-table 5 GB 30-day is $29.99 ATESIM, behind Nomad $19 and Sim Local $25.75. Live-table unlimited 30-day is $103.49 ATESIM, which is the only ranked unlimited 30-day Antigua-and-Barbuda-country floor this pass (dest unlimited block prints GigSky fair-use 2.5 GB/day then reduced, not below 100 kbps). Shorter dest rows include 1 GB / 7 days at $6.49 ATESIM, 3 GB / 15 days at $19.49 ATESIM, and unlimited day-pass style rows from 1-day through 21-day. No dest 20 GB, 25 GB or 50 GB Antigua-and-Barbuda-country row for GigSky this pass.

Yesim's Antigua and Barbuda shop technical specs print Hotspot: Depends on operator. Hotspot marketing blocks are not treated as a yes cite. Network coverage city list: Saint John's, and other cities in Antigua and Barbuda. Destinations operators payload on the Antigua and Barbuda plan objects names C & W (3G/LTE). Editorial About copy that mentions Digicel and Flow is not a carrier cite. ID verification: Not required. Barbuda-only, Codrington, Montserrat, St Kitts and Guadeloupe stay unnamed on that city list.

The bottom line

Cheapest ranked 10 GB 30-day dest total is Nomad at $34, also dest cheapest at 3 GB, 5 GB, 10 GB and 20 GB. Second is Sim Local at $44.50 on ESFX-0048-SL1 (Flow, hotspot yes). Third is GigSky at $54.99 with unpublished host and the only ranked unlimited 30-day country floor at $103.49; the 180-day 50 GB rule does not remove it because dest has no Antigua-and-Barbuda-country 50 GB SKU. Fourth is Yesim at $63.46, dest cheapest at 1 GB, with C & W on destinations operators. Slots 5 and 6 stay empty. Maya is out. Host strings this pass: Nomad FLOW (shop + 10 GB mask); Sim Local Flow (ESFX-0048-SL1); GigSky unpublished; Yesim C & W. Hotspot: Nomad and Sim Local yes; GigSky Unlimited use included; Yesim Depends on operator.

Nomad prints an overseas-territory hedge. Yesim names Saint John's on the city list. Beyond the Antigua and Barbuda country label, Sim Local and GigSky leave cities and neighbouring islands unnamed as coverage; Sim Local alone prints its generic rural hedge. No Barbuda-only, Codrington, Montserrat, St Kitts or Guadeloupe latch on the ranked Antigua-and-Barbuda-country shops. Antigua and Barbuda is outside EU/EEA RLAH.

Frequently asked questions

Does an Antigua-and-Barbuda-country eSIM cover Barbuda-only, Codrington, Montserrat, St Kitts, Guadeloupe or other Caribbean islands?

Leave Barbuda-only and neighbouring-island coverage empty for all four ranked picks unless that shop names the place. The country product label is Antigua and Barbuda on Nomad, Sim Local, GigSky and Yesim; that is the country name, not a Barbuda-only claim. Nomad shop: overseas territories may be excluded; neighbouring islands and Barbuda-only unnamed. Yesim city list: Saint John's and other cities in Antigua and Barbuda; Barbuda-only / Codrington unnamed as a separate claim. Sim Local ESFX-0048-SL1: Networks Flow; coverage Antigua & Barbuda; rural mountains/deserts/countryside hedged as variable. GigSky Antigua and Barbuda shop: host unpublished; neighbouring islands unnamed. Do not invent Caribbean island coverage from Flow, Digicel or C & W presence alone.

Can I tether or use a hotspot?

Nomad Antigua and Barbuda shop FAQ: yes, tethering / hotspot. Sim Local ESFX-0048-SL1: Hotspot and tethering Yes. GigSky shop: hotspotBody Unlimited use included. Yesim specs: Depends on operator.

Which network will I actually use?

Nomad shop: FLOW (10 GB SKU mask_network FLOW only, Antigua MCCMNC 344920_AG). Sim Local ESFX-0048-SL1: Flow. GigSky: unpublished on the shop. Yesim: C & W on the destinations operators object (3G/LTE). Opensignal has no Antigua and Barbuda GNEI country row and no dedicated Antigua and Barbuda Mobile Network Experience report this pass. DataReportal / ABS number-portability sources describe the national market and are not a shop host.

Does ATESIM 20% apply to Nomad's Antigua and Barbuda 10 GB plan?

ATESIM 20% does not apply to unlimited, add-ons, business, sale, Thailand 50 GB, or plans under USD 5. The Antigua and Barbuda 10 GB 30-day dest/shop offer is $34 this pass, so it is not under the USD 5 floor. Dest prints ATESIM on that row and on the Antigua and Barbuda 3 GB / 5 GB / 20 GB and 7-day 1 GB rows. ATESIM 20% on the Nomad programme still excludes unlimited rows.

Why are only franked picks ranked?

Dest prints only four eligible Antigua-and-Barbuda-country 10 GB 30-day programme totals this pass (Nomad $34, Sim Local $44.50, GigSky $54.99, Yesim $63.46). Ubigi has no Antigua-and-Barbuda-country SKU. Airalo has no 10 GB Antigua-and-Barbuda-country row. Saily has no Antigua-and-Barbuda-country 10 GB 30-day row. Roamless, aloSIM and ByteSim are absent. Leave slots 5 and 6 empty; do not pad with Maya, Holafly or Caribbean regional rows.

Why is GigSky still ranked when the 180-day 50 GB rule exists?

The out rule fires only when dest's cheapest Antigua-and-Barbuda-country 50 GB SKU is a GigSky 180-day row. Dest has no Antigua-and-Barbuda-country 50 GB SKU at any duration. Dest's printed 50 GB cheapest-at-size winner stays Ubigi Best World 50 GB 180-day at $99: World regional, not Antigua-and-Barbuda-country. GigSky therefore stays and ranks third on its $54.99 10 GB total.
