The short answer
Ringo Light is the cheapest unlimited eSIM for the Caribbean: $47.99 for 2 weeks and $90.99 for 30 days, unlimited data at full speed on local partner networks in 7 countries, the Bahamas, the Cayman Islands, the Dominican Republic, Jamaica, Puerto Rico, Sint Maarten and Nicaragua, priced 11 November 2026. Next are Ubigi at $75 for 15 days with 30 GB at full speed and Airalo at $160 for 30 days, and Airalo and Ubigi cover more islands, so I would check your island before anything else.
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.
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 today.
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 today. Ringo Light sells no bucket either: its 2 weeks is unlimited and lasts 2 weeks, not 30 days.

What to do in the Caribbean, and what your phone needs for it
Eight places on the islands Ringo Light covers, from San Juan to Sint Maarten, with the one thing your data does for you at each. Towns and resort coasts have good 4G; the cays, reefs and rainforests much less, so a few tips are about going offline.
If you want unlimited for two weeks or a month: Ringo Light
For two weeks or a month of unlimited data in the Caribbean, Ringo Light is the cheapest of the five I could price: $47.99 for 2 weeks and $90.99 for 30 days, if your islands are on its list. A Caribbean trip is often a week or two on one island, or a cruise that stops at four. For about two weeks of unlimited, I found Ubigi at $75 for 30 GB at full speed, Holafly at $91.90 and Airalo at $99. For a month, Airalo asks $160 and Holafly $165.50; Ubigi sells no month of unlimited here, and Nomad sells no unlimited at all. Nothing renews on Ringo Light.
I always read what unlimited means before I pick a plan. Airalo gives 3 GB a day at full speed, then 1 Mbps. Ubigi gives 20 GB for 7 days or 30 GB for 15 days, then 2 Mbps. Holafly states no daily cap for your own phone and limits sharing to 1 GB a day. Ringo Light is unlimited data at full speed for the whole 2 weeks or 30 days.
For a short trip I would not pick Ringo Light, which sells no 3-day or 7-day plan. Airalo sells 3 days of unlimited at $19.50, and Ubigi a week at $44, $3.99 under the 2 weeks on Ringo Light.
Check your island first: Caribbean plans cover different lists
The Caribbean is thirty-odd countries and territories, and no plan covers them all. This is where the brands differ most, more than on price, and it is the row I check first. Ringo Light covers 7: the Bahamas, the Cayman Islands, the Dominican Republic, Jamaica, Puerto Rico and Sint Maarten, plus Nicaragua on the mainland. It is the only plan in this table that covers both the Dominican Republic and Puerto Rico, two of the most visited places in the region.
It is also the shortest list. Airalo's Island Hopper covers 26 countries, Ubigi 27, Holafly 18 and Nomad 15. If your trip is Barbados, St Lucia, Aruba, Antigua, Turks and Caicos or the French islands, the Ringo Light Caribbean trip does not cover it: I would buy that island's own Ringo Light trip, or one of these regional plans. For an eastern Caribbean cruise, I would pick Airalo or Ubigi. I would rather you read that here than at checkout.
Networks differ island by island. 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 US networks. Every plan here roams on one or two local networks per island; cities and resort coasts are well covered, the small cays and national parks much less.

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, the Dominican Republic and Sint Maarten.
- Ubigi, $34 for 10 GB. The next cheapest 10 GB for 30 days, across 27 countries including the Dominican Republic and Sint Maarten, but not Puerto Rico.
- Airalo, $48 for 10 GB. Its Island Hopper plan, 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, I would buy Nomad or Ubigi in the Caribbean, as both are cheaper. 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 with no speed cap: 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. Ringo Light sells no 3 days.
Ringo Light unlimited, 2 weeks, $47.99, the one plan here that covers both, and less than any rival charges for two weeks.
I would pick Airalo Island Hopper or Ubigi: their lists include Barbados, St Lucia, Antigua and Aruba, which the Ringo Light Caribbean trip does not cover (each has its own Ringo Light trip).
Nomad 10 GB for 30 days at $30, or Ubigi at $34, if your island is on their list.
Ringo Light unlimited, 30 days, $90.99. A little over half what Airalo and Holafly ask.
None of these travel plans does that. The full Ringo, which Ringo Light funds, ports the number you have.
