eSIM for a Caribbean Island-Hopping Trip

For most Caribbean island-hopping trips, buy one regional eSIM before you leave, then plug the few gaps it misses. Airalo's Island Hopper eSIM covers 26 Caribbean and nearby destinations on a single profile, from 8 dollars for 1 GB over 7 days to 48 dollars for 10 GB over 30 days, and it is the best single buy for routes through Jamaica, the Bahamas, Puerto Rico, Barbados, St Lucia, Aruba and Curaçao. It does not cover the Dominican Republic, Martinique, Anguilla, the British or US Virgin Islands, or Cuba, so check your ports against the coverage table below and add a single-country eSIM where you need one. US travelers on T-Mobile's Experience More 2.0 or Experience Beyond 2.0 plans may not need to buy anything, because 5 GB or 15 GB of high-speed roaming is already included. On a cruise, switch to airplane mode when the ship leaves port and use your eSIM only on land.

The five ways to stay connected on a multi-island trip

A Caribbean itinerary is unusual because almost every stop is a different country or territory, each with its own networks and its own roaming rules. A week that takes in Nassau, St Maarten and St Thomas crosses three jurisdictions: one independent country, one Dutch constituent country and one US territory. That is why the choice matters more here than on a trip to a single destination. You have five realistic options, and most travelers end up combining two of them.

The regional eSIM wins for most people because it is the only option that keeps you online the moment you step off a plane, ferry or tender on each island without doing anything. The rest of this guide is about the exceptions: the islands the regional packs miss, the territories where your home plan already works, and the days at sea when nothing but ship Wi-Fi makes sense.

Regional Caribbean eSIMs in September 2026

Three large providers sell a Caribbean regional product, and their coverage lists are very different. Prices below were checked on 14 September 2026 and are in US dollars.

Airalo Island Hopper (26 destinations). This is the widest list. It includes Antigua and Barbuda, Aruba, the Bahamas, Barbados, Bermuda, Bonaire, the Cayman Islands, Curaçao, Dominica, Grenada, Guadeloupe, Haiti, Jamaica, Montserrat, Puerto Rico, Saint-Barthélemy, St Kitts and Nevis, St Lucia, Saint-Martin (French side), Sint Maarten (Dutch side), St Vincent and the Grenadines, Trinidad and Tobago and the Turks and Caicos, plus three mainland destinations: Panama, Guyana and French Guiana. Fixed-data plans run 1 GB for 7 days at 8 dollars, 2 GB for 15 days at 15 dollars, 3 GB for 7 or 30 days at 21 dollars, 5 GB for 7, 15 or 30 days at 30, 31 and 32.50 dollars, and 10 GB for 7, 15 or 30 days at 46, 47 and 48 dollars. Unlimited plans cost 19.50 dollars for 3 days, 33.50 for 5, 45 for 7, 60 for 10, 99 for 15 and 160 for 30, with full speed for the first 3 GB each day and 1 Mbps after that. It is a 4G, data-only eSIM that you can top up, needs no ID check, and its validity starts when it first connects in a covered country. See our Airalo review for how the app handles top-ups.

Nomad Caribbean (15 destinations). Nomad covers Anguilla, Antigua and Barbuda, the Bahamas, Barbados, the British Virgin Islands, the Cayman Islands, Dominica, Grenada, Jamaica, Montserrat, St Kitts and Nevis, St Lucia, St Vincent and the Grenadines, the Turks and Caicos, and a Netherlands Antilles entry that it does not break down by island. It runs mainly on Flow, with BTC in the Bahamas. Plans are 1 GB for 7 days at 8 dollars, then 3 GB, 5 GB, 10 GB and 20 GB for 30 days at 17, 21, 36 and 49 dollars. It is the cheapest per GB of the three and the only one that covers Anguilla and the BVI, but it skips Puerto Rico, the Dominican Republic, Trinidad and Tobago and every French island. See our Nomad review.

Holafly Caribbean (18 destinations, unlimited only). Holafly lists Antigua and Barbuda, Aruba, Barbados, Bermuda, the British Virgin Islands, the Cayman Islands, Curaçao, Dominica, the Dominican Republic, French Guiana, Haiti, Jamaica, Martinique, St Kitts and Nevis, St Lucia, St Vincent and the Grenadines, Trinidad and Tobago, and the Turks and Caicos. Prices are 19.90 dollars for 3 days, 33.90 for 5, 45.50 for 7, 60.50 for 10, 90.50 for 15 and 161.50 for 30, and you can share 1 GB a day as a hotspot. It is the only one of the three that covers both the Dominican Republic and Martinique, but it leaves out the Bahamas, Puerto Rico, Grenada, Guadeloupe and both halves of St Martin. Holafly also sells a separate Caribbean Cruise eSIM, covered in the cruise section below and in our Holafly review.

Which islands each regional eSIM actually covers

Before you buy, run your ports and airports down this table. Unclear means the provider lists a grouping rather than the island by name, so do not rely on it without asking support first.

The Dominican Republic is the biggest gap. It is one of the most visited countries in the region, yet Airalo's and Nomad's Caribbean packs both leave it out. If Punta Cana or Santo Domingo is one stop on a longer hop, pair a regional plan with a Dominican Republic eSIM, or pick Holafly if Puerto Rico and the Bahamas are not on your route.

Cuba is not covered by any mainstream regional pack. Airalo has not offered Cuba since mid-2024, and the only mobile network there is ETECSA's Cubacel. Plan Cuba as a separate purchase; our Cuba eSIM guide covers what currently works.

Bermuda is not in the Caribbean. It sits in the North Atlantic, roughly 1,000 km off the coast of North Carolina, but providers often bundle it into Caribbean products and it appears in both Airalo's and Holafly's lists. That helps if your cruise calls at Bermuda and then heads south; see our Bermuda page for the local picture.

The US Virgin Islands are missing from all three, but for US travelers that rarely matters, because US carriers treat St Thomas, St John and St Croix as domestic. Other visitors should buy a US eSIM or rely on port Wi-Fi.

Digicel and Flow: can one local SIM work across islands?

Two operator groups dominate the English-speaking Caribbean: Digicel and Flow (part of Liberty Latin America). Both run networks on many islands, so it is tempting to buy one SIM on your first island and carry it the whole way. It works, but only with a roaming add-on and only inside that operator's footprint.

Digicel. A Digicel prepaid SIM is not free to use on other Digicel islands; you buy a Caribbean roaming plan by dialing *153# or in the MyDigicel app. On Digicel Jamaica in September 2026, the combined USA, Canada and Caribbean plans are 3 GB for 3 days at JMD 800, 7 GB for 7 days at JMD 1,800 and 20 GB for 30 days at JMD 5,200, all before GCT tax. The Caribbean part of that plan works in Anguilla, Antigua and Barbuda, Aruba, Barbados, Bermuda, Bonaire, the BVI, the Cayman Islands, Curaçao, Dominica, the French West Indies, Grenada, Guyana, Haiti, Montserrat, St Kitts and Nevis, St Lucia, St Vincent and the Grenadines, Trinidad and Tobago and the Turks and Caicos. Digicel's Caribbean Roaming terms published for Bonaire (last updated October 2025) list 3-day and 7-day passes at 15 and 29 US dollars. Note what is missing: the Dominican Republic, Puerto Rico and the Bahamas.

Flow. Flow has promoted a Travel Pass feature that lets a prepaid data bundle bought in one Flow market be used in the others: Anguilla, Antigua, the BVI, the Cayman Islands, Curaçao, Dominica, Grenada, Jamaica, Montserrat, St Kitts and Nevis, St Lucia, St Vincent and the Grenadines, and the Turks and Caicos. We could not load Flow's current terms page to confirm the 2026 wording, so ask at the store before you rely on it. If it applies, it is a genuinely good deal for an Eastern Caribbean sailing, because you pay local bundle prices and roam at no extra cost.

US carriers: what AT&T, Verizon and T-Mobile include in 2026

Start with the easy part. Puerto Rico and the US Virgin Islands count as domestic on AT&T, Verizon and T-Mobile, so your normal plan works there with no pass and no roaming charge. Everywhere else in the Caribbean is international.

AT&T. No AT&T plan includes Caribbean islands for free. The International Day Pass costs 12 dollars a day on land, plus 6 dollars for each additional line used the same day, and requires an unlimited plan. Its destination list covers most of the region, including Antigua, the Bahamas, Barbados, Bermuda, the BVI, the Cayman Islands, Dominica, the Dominican Republic, Grenada, Guadeloupe, Haiti, Jamaica, Martinique, Montserrat, Saint-Barthélemy, St Kitts, St Lucia, both halves of St Martin, St Vincent, Trinidad and Tobago and the Turks and Caicos.

Verizon. Verizon's unlimited plans include Mexico and Canada, but not the Caribbean. TravelPass costs 12 dollars a day in the Caribbean (6 dollars in Mexico and Canada), and TravelPass days cannot be used on cruise ships.

T-Mobile. This is the one US plan that can replace an eSIM. Experience More 2.0 includes up to 5 GB of high-speed data in 215+ countries and destinations, and Experience Beyond 2.0 includes up to 15 GB, then unlimited data at up to 256 kbps. Calls cost 0.50 dollars a minute. The Caribbean list covers the English, Dutch and French islands but, as far as we can tell, not Cuba. Customers who need more high-speed data can buy an International Pass: 512 MB for 1 day at 5 dollars, 15 GB for 10 days at 50 dollars, or 30 GB for 30 days at 75 dollars.

French and Dutch islands: where EU roaming does and does not apply

European travelers often assume every French or Dutch island counts as Europe for roaming. It does not. EU Roam Like at Home rules apply to member states and their outermost regions, and in the Caribbean area those are Guadeloupe, Martinique, French Guiana and Saint-Martin. The Netherlands' six Caribbean islands and Saint-Barthélemy are Overseas Countries and Territories (OCTs). The European Commission states plainly that OCTs are not part of EU territory.

St Martin and Sint Maarten are one island but two territories. The French north is inside the EU; the Dutch south is not, and it has its own operators and its own prices. Phones pick whichever tower is strongest, and the border is an unmarked road, so an EU visitor staying in Marigot can easily end up billed at non-EU rates from a Dutch-side mast. Select a French-side network manually in your phone's settings if you rely on EU roaming. Travel eSIMs list the two halves separately too: Airalo covers both, Nomad and Holafly's Caribbean plan cover neither by name, and Holafly's Cruise eSIM lists Saint Martin.

Even inside the outermost regions, check your own tariff. Some European operators apply fair-use limits or treat the overseas departments differently from mainland France, and UK plans are not covered by EU rules at all.

Caribbean cruises: at sea versus in port

A cruise is really two different connectivity problems. In port, your phone connects to the island's networks exactly as it would on a land trip, so a regional eSIM or your carrier's day pass works normally. At sea, once the ship is in international waters, the only cellular signal comes from the ship's own maritime network, run by companies such as Cellular at Sea and Wireless Maritime Services and relayed by satellite. Your home carrier bills that usage on your next statement at cruise rates, and regional travel eSIMs do not work on it.

What the big three US carriers charge at sea in 2026:

AT&T offers International Day Pass on more than 400 cruise ships at 20 dollars a day, covering land and sea, with unlimited talk and text and 500 MB of high-speed data per day. Verizon's Cruise Daily Pass is 20 dollars per line for each day you use service on board. It starts about 12 miles after leaving the dock and includes 0.5 GB of high-speed data, then slower speeds. T-Mobile has no cruise data pass; the ship network is pay-per-use, and T-Mobile shows per-minute, per-text and per-MB rates for each ship on its cruise roaming page. Maritime pay-per-use data has historically cost several dollars per MB, so a phone left to refresh apps in the background can run up a large bill before you notice.

Holafly sells a Caribbean Cruise eSIM built around common ship routes: the USA, Mexico, the Bahamas, the Cayman Islands, Colombia, the Dominican Republic, Honduras, Jamaica, Panama, Puerto Rico and Saint Martin, at 17.90 dollars for 3 days, 39.50 for 7 and 97.90 for 30. It works on land only, and Holafly says it does not work in Freeport, CocoCay or Ocean Cay in the Bahamas, which matters because private cruise islands are among the most common stops. It suits Western Caribbean cruises, where ports such as Cozumel, Roatán and Cartagena fall outside Airalo's Island Hopper list; for Cozumel and Costa Maya, a Mexico eSIM is another option.

What to buy for common island-hopping routes

Eastern Caribbean cruise from Florida (Nassau, St Thomas, St Maarten, a private island). Airalo Island Hopper covers the Bahamas and Sint Maarten. St Thomas is domestic for US carriers, so American passengers need nothing extra there. Airplane mode at sea.

Southern or Windward Islands sailing (Antigua, St Kitts, St Lucia, Barbados, Grenada). Island Hopper and Nomad both cover every stop. Nomad is cheaper per GB; Island Hopper adds Trinidad and Tobago if the route continues south.

The ABC islands (Aruba, Bonaire, Curaçao). Island Hopper is the only regional plan that clearly names all three. Holafly covers Aruba and Curaçao but not Bonaire.

Greater Antilles (Jamaica, Dominican Republic, Puerto Rico). No single regional plan covers all three. US travelers can use Holafly Caribbean for Jamaica and the Dominican Republic and their home plan in Puerto Rico. Everyone else should combine Island Hopper, which covers Jamaica and Puerto Rico, with a Dominican Republic eSIM.

British Virgin Islands charter. Nomad or Holafly Caribbean covers the BVI; Airalo does not. If you cross to St John or St Thomas, US plans work as domestic.

French Antilles (Guadeloupe, Martinique, St Barts). EU residents can usually use their home plan in Guadeloupe and Martinique, but not in St Barts. Non-EU travelers should note that Airalo covers Guadeloupe and St Barts but not Martinique, while Holafly covers Martinique but not the other two.

Adding Cuba to any route. Buy a separate plan and expect patchy data; no regional eSIM will carry you there.

Set it up before you fly or board

Cruise port calls are short and island airports often have weak Wi-Fi, so do everything at home. First, check your phone is unlocked and supports eSIM; our what is an eSIM explainer covers the basics. Install the regional eSIM on home Wi-Fi a day or two before departure using our step-by-step install guide. Airalo's Island Hopper plans only start their validity when they first connect in a covered destination, so installing early costs you no days.

Then set your phone up as a dual-SIM traveler: the eSIM as the data line with data roaming switched on (regional eSIMs need it), and your home SIM kept on for calls and SMS codes with its own data roaming switched off. If you are unsure how much data to buy, how to choose a data plan walks through the sizing. To compare plans island by island, run your first stop through the eSIM Finder and check the country pages for Jamaica, the Bahamas, the Dominican Republic and Puerto Rico for local network detail.

Frequently Asked Questions

Is there one eSIM that covers every Caribbean island?

No. Airalo's Island Hopper has the widest list at 26 destinations, but it skips the Dominican Republic, Martinique, Anguilla, the British and US Virgin Islands, Saba, Sint Eustatius and Cuba. Nomad's Caribbean plan covers Anguilla and the BVI but misses Puerto Rico and the Dominican Republic, and Holafly's covers the Dominican Republic and Martinique but misses the Bahamas and Puerto Rico. Check your exact stops and pair a regional plan with a single-country eSIM for any gap.

Will my travel eSIM work on the cruise ship between islands?

No. At sea your phone can only connect to the ship's maritime network, such as Cellular at Sea, and that usage is billed by your home carrier at cruise rates, not by your eSIM. Put your phone in airplane mode when the ship leaves port, use ship Wi-Fi if you need to be online, and switch the eSIM back on when you dock. AT&T and Verizon sell 20 dollar a day cruise passes if you must use cellular at sea.

Do I need separate plans for St Martin and Sint Maarten?

Not with Airalo's Island Hopper, which lists both the French and Dutch sides and covers them on one plan. They are still different territories with different networks: French Saint-Martin is part of the EU and Dutch Sint Maarten is not. EU travelers relying on Roam Like at Home should manually select a French-side network, because phones often grab Dutch-side towers and bill at non-EU rates.

Can I use a Digicel SIM from Jamaica on other Caribbean islands?

Yes, but only with a roaming add-on. In September 2026, Digicel Jamaica sells combined USA, Canada and Caribbean plans from 3 GB for 3 days at JMD 800 before tax, valid in Digicel markets such as Barbados, St Lucia, Grenada, Antigua, the Cayman Islands, Curaçao and Aruba. The pass does not cover the Dominican Republic, Puerto Rico or the Bahamas.

Do US phone plans work in Puerto Rico and the US Virgin Islands on a Caribbean trip?

Yes. AT&T, Verizon and T-Mobile treat Puerto Rico and the US Virgin Islands as domestic, so your normal allowance works with no day pass. Every other Caribbean island is international: AT&T and Verizon charge about 12 dollars a day, while T-Mobile Experience More 2.0 and Experience Beyond 2.0 include 5 GB and 15 GB of high-speed roaming.

Does EU roaming work in Guadeloupe, Martinique and St Barts?

Guadeloupe and Martinique are EU outermost regions, so EU Roam Like at Home rules apply there, subject to your operator's fair-use terms. Saint-Barthélemy left the EU in 2012 and is now an Overseas Country and Territory, so EU roaming rules do not apply and most European operators bill it at non-EU rates. The same is true of Sint Maarten, Aruba, Curaçao and Bonaire.

Is Bermuda covered by Caribbean eSIM plans?

Often, yes. Bermuda is in the North Atlantic, not the Caribbean, but Airalo's Island Hopper and Holafly's Caribbean plan both include it, which helps on cruises that call at Bermuda before heading south. Nomad's Caribbean plan does not list Bermuda.
