Quick verdict by trip type
For a single resort stay, a country-specific eSIM (Dominican Republic, Jamaica, etc.) is cheapest. For island-hopping, a multi-island cruise, or a trip that touches several Caribbean nations, a regional bundle is the low-stress choice. One thing we should say plainly: the Caribbean is our weakest region on price. Checked in August 2026, Nomad's 15-country Caribbean bundle was far cheaper per gigabyte than ours, though it covers fewer islands than our 25-country plan. The unlimited alternatives are the most expensive passes either Airalo or Holafly sells anywhere — around $160 for 30 days. Compare the dated index below on both price and island coverage before you buy.
| Trip type | Best pick | Why |
|---|---|---|
| Single all-inclusive resort stay | Country-specific eSIM (e.g. Dominican Republic, Jamaica) | Cheaper than the 25-island bundle for a one-country trip |
| Multi-island cruise or island-hopping trip | Flysimio Caribbean 5–10 GB | Roams across islands automatically — no re-buying at each port |
| Short cruise stop, light data use | A 1 GB / 7-day regional plan | Any of them beats cruise-ship Wi-Fi — but compare the index above, Nomad was materially cheaper in August 2026 |
| Extended multi-island trip, heavy streaming | Flysimio Caribbean 10 GB or Airalo unlimited | Compare the fixed 10 GB price against Airalo's unlimited if you'll stream heavily |

How this table is priced. Flysimio prices are read live from our carrier catalog every time this page loads, so the figure here is the figure at checkout. Competitor prices are the US-dollar price shown on each provider's own site, read on the date in the last column and linked to the page we read it from; promotional prices are marked alongside the list price. Price per GB is the plan price divided by its included data — unlimited passes have no per-GB figure and are ranked by total price instead.

Which Caribbean islands are covered?
The bundle covers 25 islands and territories, including the Dominican Republic, Jamaica, the Bahamas, Barbados, Puerto Rico, Trinidad and Tobago, the Cayman Islands, Turks and Caicos, Aruba, Curaçao, Saint Lucia, and more — plus the South American mainland countries of Colombia, Brazil, Argentina, Peru, Bolivia, and Uruguay that ship with the same bundle.
Is this good for a Caribbean cruise?
Yes, with one important caveat: coverage is land-based. Your eSIM connects to a local carrier network whenever your ship is in port or close to shore — it does not work in open water between islands. That's still far cheaper and faster than cruise ship Wi-Fi packages, which are among the most expensive connectivity options anywhere. See our dedicated cruise ship eSIM guide for port-by-port detail.
Which Caribbean carriers your eSIM actually uses
- Dominican Republic: Altice, Claro — strong 4G/5G across the Punta Cana resort corridor and Santo Domingo.
- Jamaica: Digicel, Flow — solid coverage in Montego Bay, Negril, and Kingston.
- Bahamas: BTC, Aliv — good coverage in Nassau and the main cruise ports.
- Puerto Rico: AT&T, Claro — US-standard 4G/LTE network quality.
Caribbean eSIM coverage by island
- Dominican Republic — Altice and Claro cover the entire Punta Cana resort corridor and Santo Domingo's Zona Colonial. See the Dominican Republic country guide for a single-island plan.
- Jamaica — Digicel and Flow cover Montego Bay, Negril, and Kingston with reliable 4G.
- Bahamas — BTC and Aliv cover Nassau and the main cruise terminal areas.
- Barbados, Puerto Rico, Trinidad and Tobago — each has solid 4G in the main tourist and resort zones under the regional bundle.
Frequently asked questions
What is the best eSIM for a Caribbean cruise?
A Flysimio Caribbean regional eSIM covers 25 islands on one line, connecting automatically in port. It's far cheaper than cruise ship Wi-Fi packages, though it only works on land or close to shore, not in open water.
Does this work for island-hopping between countries?
Yes — the eSIM roams across the 25 covered islands and countries automatically. Coverage depends on being in range of a partner network on land; open-water crossings between islands have no signal.
Is a single-island eSIM cheaper than the regional bundle?
Yes, for a one-country stay. Country-specific plans for the Dominican Republic, Jamaica, or the Bahamas are cheaper per GB than the 25-island regional bundle. The regional plan makes sense once you're visiting two or more islands.
How does this compare to cruise ship Wi-Fi?
Far cheaper. Cruise Wi-Fi packages are among the most expensive connectivity options at sea, often charging per day for slow, capped access. A land-based eSIM costs a fraction of that whenever you're in port.
Do I need to activate before I travel?
No. You have six months from purchase to activate — the validity period only starts counting down when your eSIM first connects to a network in the region.
Can I top up if I run out of data mid-cruise?
Yes. Top up from your Flysimio account dashboard at any port with signal — it applies instantly without needing a new eSIM.
