41 of these 539 plans were checked against the seller's own shop on 17 October 2026. The rest come from the seller's own feed or plan pages and are not yet independently checked.
The Watchdog Pick is the lowest real price per GB of the 539 plans in this view. Bulk data pools above 50 GB cannot win it, because their per GB rate only exists if you use data no traveller uses. Providers cannot pay for it. Unlimited plans show their fair use allowance instead of a per GB rate, because there is no per GB rate to compare.
Price per GB counts only data you can use inside the validity, at most 3 GB a day, so a big pool on a short validity cannot buy the top spot. Every provider's best two plans come first, then the rest. A plan marked Unverified price undercuts every other provider here by more than half and waits at the end until we have checked it on the seller's site. How we rank
Unlimited rows show the daily amount at full speed. Some rows also show the speed after that amount. A row with no speed does not mean the plan stays fast, so check the plan on the seller's site.
Some links here earn us a commission. It never changes the order. How we make money The row marked Sponsored is a paid placement shown above the ranking, not part of it. Advertise here.
Short answer. The cheapest Caribbean eSIM we track right now is MobiMatter, 25 GB for 30 Days at $19.99, which is $0.80 per GB, covering 3 countries on one eSIM. Checked 17 October 2026, 06:01 GMT.
The Caribbean is dozens of small markets rather than one, so a regional plan here does more work than in most regions. It is also the region where a plan name tells you the least about what is actually covered.
What the cheapest Caribbean eSIM costs right now
As of 17 October 2026, 06:01 GMT, the best rate on a Caribbean plan is MobiMatter at $0.80 per GB: 25 GB for 30 Days at $19.99, across 3 countries. The median across all 539 plans is $7.41, so half of what is sold in this region costs more than that.
- Smallest ticket price GigSky, 1 GB for 7 Days at $2.99. Useful for a short hop, rarely the best value per GB.
- Best rate on a large plan MobiMatter, 25 GB for 30 Days at $19.99, $0.80 per GB. Buying bigger is almost always cheaper per GB than topping up twice.
- Longest validity Roamix, 365 Days on one plan. Long itineraries lose money on short plans that have to be replaced.
- Features across these plans 197 can be topped up, 270 advertise 5G, 461 allow hotspot use, and 272 are sold as unlimited.
Which is the best eSIM for Caribbean?
Best depends on the trip, so here are the winners on today's numbers rather than one name. Each line is the first row of a different sort on the 539 live plans above:
- Best value MobiMatter, 25 GB for 30 Days at $19.99: $0.80 per GB across 3 countries.
- Widest coverage GigSky, 48 countries on one eSIM, 512 MB for 1 Day at $10.99.
- Best for a long trip Roamix, 365 Days on one plan, Unlimited500 MB/day at $2,018.45.
- Highest daily cap on an unlimited plan Roamix, 365 Days at $26,904.10, full speed up to 10 GB a day. Set that daily cap against the fixed plans before you pay for the word unlimited.
A Caribbean eSIM only earns its keep once you cross a border. If the whole trip stays in one country, the single country plan usually wins, and the next section prices both sides.
Is a Caribbean eSIM worth it, or is one plan per country cheaper?
This is the comparison that decides the purchase, and nobody publishes it, so here it is from our own catalogue. We price both sides on the same basket: a plan of 5 to 50 GB lasting at least 15 days, which is what a real trip needs. Bulk data pools are excluded from both sides, because nobody buys 500 GB for a fortnight.
That regional figure is MobiMatter, 25 GB for 30 Days at $19.99, covering 3 countries. The country figure is the average of the cheapest comparable plan in each of the 28 countries we have prices for in this region.
The regional plan wins outright here, and it is not close. It comes in around 63% under the average country's own best plan at the same size. In a region where single country data is expensive, buying the regional plan is the default choice rather than the convenience option.
The averages hide a wide spread, and the spread is where the decision actually lives. The cheapest country in this region is St Barthelemy at $0.40 per GB on its own plan, well under the regional rate. The dearest is Cuba at $10.00. If your itinerary leans towards the expensive end, the regional plan is worth more than the averages suggest. If it leans cheap, buy per country.
How many countries does a Caribbean eSIM actually cover?
There is no standard. Across the 539 plans on this page the country lists differ enormously, and the name on the plan tells you almost nothing. These are the widest plans each provider currently sells in this region.
| Provider | Widest plan | Plans here | Best per GB |
|---|---|---|---|
| GigSky | 48 countries | 22 | $1.20 |
| Tourist eSIM | 39 countries | 55 | $4.63 |
| FlyEsim | 39 countries | 50 | $5.62 |
| MobiMatter | 37 countries | 30 | $0.80 |
| eSIModo | 31 countries | 89 | $3.24 |
| Saily | 29 countries | 3 | $5.20 |

Island hopping, cruises and Cuba
Country lists vary wildly between providers here. Two plans both called Caribbean can differ by more than a dozen islands, and the one you want may be on neither. The live figures above show the current state for the islands people ask about most.
Cuba is its own case. It is not on the regional packs we track at all, and travellers going there should plan for local options rather than expect a regional eSIM to work.
Cruises are the other trap. At sea your phone connects to a maritime network on the ship, which no travel eSIM covers and which bills at satellite rates. Turn data off until you are back on land, and buy the eSIM for the islands you actually walk on.
Are the unlimited Caribbean plans really unlimited?
No, and they are not sold as a trick either. 267 of the 539 plans here are unlimited in the fair use sense: full speed up to a daily allowance, then slower until the clock resets. A further 5 plans are unlimited in a different way: one capped speed for the whole plan, shown next to the word Unlimited in the table. The published daily allowances on these plans currently run from 0.5 GB to 10 GB a day. Past the cap the speed drops, often to 1 Mbps or less, which is fine for messages and maps and painful for video.
That is why unlimited plans carry no price per GB in our table. There is no honest per gigabyte number to print, so we show the daily allowance instead and leave the value verdict blank rather than invent one. At $0.80 per GB from the cheapest fixed plan here, unlimited only pays off if you genuinely burn several gigabytes a day.
How to pick the right Caribbean plan
Check the country list, not the plan nameOpen the plan and read which countries it covers. The table above shows the country count for every plan, and the shares further up show how often the tricky ones are actually included.
Compare against the single country pagesThe cheapest plan for your main stop may beat the regional plan outright. Here the regional plan is far cheaper than the average country plan, so check both before you pay.
Size it for the trip, not the weekA week of island travel rarely needs more than 3 to 5 GB unless you are working. Resort wifi covers most of the rest. Use the filters on this page to set a minimum size and length, then compare only what clears the bar.
Install before you flyScan the QR code on wifi at home. Installing needs a working connection, which is the one thing you will not have when you land.
Every destination covered by a Caribbean plan
These 27 destinations are covered by at least one of the plans on this page. No single plan covers them all, so treat this as the list of places worth checking rather than a promise. Several of these plans also reach countries outside the region, which is worth knowing if your trip crosses into one. Each name links to its own price comparison.

The questions people actually ask before buying a multi country plan
What is the cheapest Caribbean eSIM right now?
Ranked by real price per GB, the cheapest is MobiMatter at $19.99 for 25 GB over 30 Days, which works out to $0.80 per GB across 3 countries. Prices move, and the table on this page is re-ranked every time our catalogue refreshes.
How many countries does a Caribbean eSIM cover?
It varies by plan, which is the single most important thing to check. Across the 539 plans we track, the widest is GigSky at 48 countries on one eSIM. Others cover far fewer. Always open the plan and read its country list before you pay.
Which is the best Caribbean eSIM?
Best depends on the trip, so we rank rather than pick one name. On today's prices the best value is MobiMatter at $0.80 per GB, while the widest coverage is GigSky with 48 countries on one eSIM. For heavy daily use there are 267 unlimited plans with daily fair use caps. Every pick is the first row of a sort on live prices, and no provider can pay for it.
Is a Caribbean eSIM cheaper than buying one eSIM per country?
On a normal trip size, which we take as 5 to 50 GB over at least 15 days, the cheapest Caribbean regional plan works out at $0.80 per GB (MobiMatter, 25 GB for 30 Days at $19.99). The average of the cheapest single country plan at that same size, across the 28 countries we price here, is $2.15 per GB. The regional plan is the clear winner here, by a wide margin, even before you count the convenience. The countries at the cheap end of the region still undercut it, so check your main stop before you decide.
Do Caribbean eSIM plans offer unlimited data?
267 of the 539 plans here are sold as unlimited. In practice almost all of them are fair use: full speed up to a daily allowance, then slower for the rest of the day. The daily allowances on these plans currently run from 0.5 GB to 10 GB. That is why unlimited plans carry no price per GB in our table: there is no per GB rate to compare.
Does a Caribbean eSIM work on a cruise ship?
No. At sea the ship runs its own maritime network, which travel eSIMs do not cover and which charges satellite rates. Keep data switched off on board and use the eSIM in port.
Is Cuba covered by Caribbean eSIM plans?
Not on the plans we track. Cuba sits outside these regional packs, so plan for local options if it is on your route.
Which islands are most likely to be included?
The larger markets, and the ones with the most tourism, are on the widest range of plans. The coverage figures on this page are read from the live plan lists, so they show which islands are safe to assume and which need checking.
Can I top up if I run out mid trip?
197 of the 539 plans here can be topped up, so you add data instead of buying a second eSIM. The rest need a fresh plan. Topping up is normally dearer per GB than sizing the plan correctly at the start.
How much data will I actually need?
A week of island travel rarely needs more than 3 to 5 GB unless you are working. Resort wifi covers most of the rest. Use the filters on this page to set a minimum size and compare only the plans that clear it.
Will I keep my own number and still get bank codes?
Yes, as long as you leave your home SIM active. These are data only eSIMs and your phone can run both at once. Keep the home line on for SMS and one time codes, switch its roaming data off, and use the eSIM for everything else.
Do these plans include calls or a phone number?
No. The plans we compare are data only, so there is no local number to give out. Calls work normally over WhatsApp, FaceTime or any app that runs on data. If you need a real local number, a local SIM is the right tool.
Compare another region
Every region we track, ranked by the cheapest real price per GB, sits on the regional and global eSIM hub. If your trip stays in one country, the country by country comparison will nearly always be cheaper.
