The short answer
Many Caribbean cruises call at Nassau, a port in Jamaica, one in the Dominican Republic and San Juan, in some order. I priced the Caribbean plans for those four on the same day, for the days the ship is docked. I would buy Ringo Light, because it is the only plan I read that lists all four. For a cruise of a week or less, a rival is cheaper.
Unlimited data at full speed in 7 countries for 2 weeks at $47.99 or 30 days at $90.99, nothing renews. The cheapest rival asks $75 for 15 days and $160 for the month.
7 days of unlimited at $44 with 20 GB at full speed, and 10 GB for 30 days at $34, across 27 countries including the Dominican Republic. It leaves out Puerto Rico.
Its Island Hopper plan covers 26 countries, Puerto Rico included, the Dominican Republic not. 3 days of unlimited at $19.50.
10 GB for 30 days at $30 and 20 GB at $42 on FLOW and BTC, but only 15 countries, without Puerto Rico or the Dominican Republic.

The prices, charted
US dollars, 11 November 2026. Ringo Light sells 14 days, the others 15. Ubigi's 15 days is 30 GB at full speed, then 2 Mbps. Nomad sells no unlimited plan here. Saily could not be read on the day.
The 30-day unlimited plan at each brand that sells one. Ringo Light is unlimited data at full speed. Ubigi's Caribbean plan stops at 15 days.
Holafly sells no buckets. Saily could not be read on the day. Ringo Light sells no bucket either: its 2 weeks is unlimited and lasts 2 weeks, not 30 days.

Where a Caribbean cruise calls, and what your phone needs at each port
Eight places that cruise days in the Bahamas, Jamaica, the Dominican Republic and Puerto Rico often include, with the one thing your phone does for you at each. One regional eSIM works in every port the ship docks at.
One plan for the whole cruise: Ringo Light
A cruise ship wakes up in a different country every day or two. With country eSIMs you would install one per port and remember which line to switch on before you step off the ship. One regional eSIM is installed at home, and the phone joins a local network in each port when the ship docks. Ringo Light's Caribbean trips cost $47.99 for 2 weeks and $90.99 for 30 days, unlimited data at full speed, and nothing renews. On the same day I read Ubigi at $75 for 15 days, Holafly at $91.90 and Airalo at $99. For a month, Airalo asks $160 and Holafly $165.50.
I added up Ringo Light's own plans for four ports. The Bahamas' 2 weeks is $44.99, Jamaica's $51.99, the Dominican Republic's $44.99 and Puerto Rico's $18.99 on their own pages, $160.96 together, against $47.99 for the Caribbean trip that covers all four. For a month, the Bahamas is $86.99, Jamaica $101.99, the Dominican Republic $56.99 and Puerto Rico $33.99, $279.96 together, against $90.99.
Two cases favour something else. If one port is the whole reason for the eSIM, a country plan can be cheaper, and Puerto Rico's 2 weeks at $18.99 is the cheapest of all. For a cruise of a week or less, Ringo Light sells no 7-day plan. Ubigi's 7 days at $44 and Airalo's at $45 cost $3.99 and $2.99 less than Ringo Light's 2 weeks, if your ports are on their lists.
Which plans cover the ports, and what happens at sea
I checked the four ports against the coverage row of the Caribbean page. Ringo Light covers all four, the Bahamas, Jamaica, the Dominican Republic and Puerto Rico. Airalo covers the Bahamas, Jamaica and Puerto Rico but not the Dominican Republic. Ubigi covers the Bahamas, the Dominican Republic and Jamaica but not Puerto Rico. Holafly covers Jamaica and the Dominican Republic but not the Bahamas or Puerto Rico. Nomad covers the Bahamas and Jamaica but not the Dominican Republic or Puerto Rico. I could not read Saily on the day.
Ringo Light has the shortest island list, 7 countries. If your ship also calls at Barbados, St Lucia, Antigua, Aruba or the French islands, the Ringo Light Caribbean trip does not cover them. For a cruise with those ports I would pick Airalo or Ubigi, whose lists run to 26 and 27 countries. Digicel and Flow run most of the English-speaking islands, Aliv and BTC the Bahamas, Altice and Claro the Dominican Republic, and Puerto Rico runs on the big American networks.
Now the part no eSIM can fix. At sea your phone is on the ship's own network or on nothing. An eSIM works in each port when the ship docks, and on shore excursions. Roaming on the ship's satellite network is billed by the ship, not by any eSIM brand. I would turn data roaming off at sea, so the phone does not join that network by itself.
If you want a data bucket: Nomad or Ubigi
- Nomad, $30 for 10 GB. The cheapest 10 GB and the only 20 GB bucket, at $42. Its list of 15 countries leaves out Puerto Rico and the Dominican Republic.
- Ubigi, $34 for 10 GB. The next cheapest 10 GB for 30 days, across 27 countries including the Dominican Republic, but not Puerto Rico. Enough for maps and ticket QR codes on port days.
- Airalo, $48 for 10 GB. Its Island Hopper plan, with buckets from $8 for 1 GB over 3 days.
- ✓Ringo Light, no buckets. The 2 weeks is unlimited for $47.99 and the 30 days unlimited for $90.99. For a fixed amount of data on a short cruise, I would buy Nomad or Ubigi, since both cost less. Buy Ringo Light for unlimited, not for a bucket.
What Ringo Light is
I write for Ringo, so read the Ringo Light rows with that in mind. Ringo Light is the data eSIM Ringo sells to fund the full Ringo, one plan that works everywhere with your own number ported onto it. For the Caribbean it sells two trips on one eSIM across 7 countries, both unlimited data at full speed: 2 weeks at $47.99 and 30 days at $90.99. Nothing renews. The eSIM arrives by email in seconds and installs in one scan, no app.
The card to buy it is further up this page, just after the side-by-side table.
Pick by trip
Airalo unlimited, 3 days, $19.50, if the Dominican Republic is not a port. Ringo Light sells no 3 days.
Ubigi, 7 days at $44, if Puerto Rico is not a port, or Airalo at $45, if the Dominican Republic is not. Ringo Light's 2 weeks at $47.99 covers all four.
Ringo Light unlimited, 2 weeks, $47.99, against $75 for 15 days at Ubigi.
Ringo Light unlimited, 30 days, $90.99, a little over half of Airalo's $160.
Nomad 10 GB for 30 days at $30, or Ubigi at $34, if your ports are on their list.
The country plan. Puerto Rico's 2 weeks is $18.99, and a phone plan from the USA may need nothing there.
