Brands do not own Caribbean networks
Travel eSIM brands are resellers. They buy access to local mobile networks in each country rather than running their own masts across Caribbean.

Islands inside Caribbean
A regional Caribbean plan covers a defined set of islands, and the list varies by brand. The destinations below appear in the sourced coverage lists; dedicated per-country rankings are in progress, so these are shown as text for now, not links. Some regional plans exclude one or two islands, so always check the brand's own coverage list before relying on a single eSIM.

How coverage works
Why Caribbean eSIM coverage changes by country
A regional eSIM does not own a single Caribbean-wide network. In each country it connects through a local carrier, so the same brand can perform well in one country and weaker in another. Simscanner checks country-level networks where data is available.
They connect through local carriers
In each Caribbean country a regional plan routes onto one or more local carriers. The local network , not the brand badge , decides real-world reach and speed.
Carrier mapping pending verification.Performance varies country to country
A brand can perform well in one country and weaker in a neighbouring one. That is why a regional ranking is paired with country-level pages, where the detail lives.

Unlimited and FUP
Unlimited data and fair use policy for Caribbean
Many regional eSIMs label plans as unlimited, but apply a fair use policy that reduces speed after a daily or total allowance. The table below compares the allowance, throttle, and hotspot rule for each brand's Caribbean plan.
FUP means fair use policy. It is the limit after which speed may be reduced. A clear FUP lists the allowance, the throttle speed, and whether hotspot is allowed.
| Brand | Unlimited offered? | High-speed allowance | Throttle after FUP | Hotspot allowed? | Policy clarity | Confidence |
|---|
Policy clarity scores how clearly each brand publishes its FUP allowance, throttle speed, and hotspot rule. No FUP threshold is shown until it is sourced.
Speed and reliability
Speed and reliability across Caribbean
Speed differs by country and by city. A regional plan that is fast in one capital can be slower in another, depending on the local network it connects to. The table below shows speed and reliability per brand, scoped to a chosen city.
| Brand | Avg download | Avg upload | Latency | 4G / 5G | City confidence | Reliability |
|---|
Speed data comes from public network performance sources, scoped per city. City-level data is required before any speed claim is shown.

FAQ
Frequently asked questions about Caribbean eSIMs
Common traveller questions answered directly. Full FAQ content stays in the HTML so search and AI crawlers can read it.
What is the best eSIM for the Caribbean?
The best Caribbean travel eSIM is the brand whose regional plan covers the islands on your route with clear fair use terms. All seven brands Simscanner tracks sell a Caribbean regional eSIM that island-hops on one plan, covering 18 to 29 islands by brand. Only Holafly's Caribbean plan is unlimited; the rest are fixed-data tiers from about $8.00. A named overall winner publishes once per-brand coverage, speed, and review scores are verified.
Is one Caribbean eSIM enough for multiple islands?
A regional Caribbean plan covers a defined set of islands under one purchase, so for many trips a single eSIM is enough. The exact list varies by brand: Nomad and Saily reach 29 islands, Airalo 26, HelloRoam 25, Jetpac 21, and Holafly 18. Some plans exclude one or two islands inside the region, so always check the coverage list before relying on it.
Do Caribbean eSIMs work the same on every island?
Not always. A regional eSIM rides on different local networks on different islands, and brands set their own coverage lists. A brand can perform well on one island and weaker on another. Simscanner verifies the local network behind each island before showing it, rather than inventing carrier mappings.
Which Caribbean eSIM has unlimited data?
Of the brands Simscanner tracks, Holafly's Caribbean regional plan is the clearest unlimited option: high-speed data to about 90 GB a month, then a temporary reduction to 256-1024 kbps under fair use. Ubigi sells a separate unlimited Caribbean tier alongside fixed-data plans, and Airalo offers an unlimited tier giving 3 GB a day before throttling to 1 Mbps. The other tracked brands sell fixed-data Caribbean plans only.
What is FUP on a Caribbean eSIM?
FUP means fair use policy. It is the limit after which a brand may reduce the speed of an unlimited plan. A clear FUP lists the high-speed allowance, the throttle speed after the cap, and whether hotspot is allowed. Holafly, for example, runs high-speed to about 90 GB a month then 256-1024 kbps; Airalo's unlimited tier gives 3 GB a day before 1 Mbps. The FUP table on this page lists these per brand.
Can I use hotspot with a Caribbean eSIM?
Hotspot and tethering rules vary by brand. Airalo, Nomad, Saily and Ubigi allow hotspot on their Caribbean plans, and Holafly allows sharing of about 1 GB a day. Jetpac's hotspot rule for the Caribbean is pending verification. The unlimited and FUP table on this page shows the hotspot rule for each brand.
Why do per-country details still matter for the Caribbean?
A regional eSIM is convenient, but performance still varies by island and by the local network the eSIM connects to. Coverage, speed, and reliability can differ between a major resort area and a quieter island. Simscanner has no dedicated Caribbean country page yet, so per-island detail is shown as text until those pages ship.
Does Simscanner accept payment from a brand to rank higher in Caribbean?
No. Region rankings come only from sourced data measured against published methodology. No brand pays for ranking position, inclusion, language, or visibility. Editorial decisions are independent of any commercial relationship. The full policy lives at the zero paid placements page.
