Caribbean eSIM
The complete guide.
Best eSIM for the Caribbean
A regional Caribbean eSIM lets you roam between islands on one plan — ideal for island-hopping, a multi-stop holiday, or a cruise that calls at several ports. One Flysimio QR keeps you online across the major Caribbean destinations, from the Dominican Republic to Jamaica, the Bahamas, and Barbados, with no swapping SIMs at each island. Plans are prepaid with no contract and no roaming surprises, and every plan includes free mobile hotspot and a 7-day money-back guarantee. It's a far cheaper, faster alternative to resort and cruise Wi-Fi packages, which are among the most expensive connectivity you can buy.
Regional Caribbean plan vs. buying per island
For a single-island stay — a week in the Dominican Republic, say — our dedicated country eSIM is usually the cheapest option. But for a trip touching multiple islands, the regional bundle wins on convenience: one eSIM roams across the coverage list, so you don't need a new plan on every island. It's especially valuable on a cruise or a multi-island honeymoon, where buying a local SIM at each stop is impractical. Note that coverage is on land — you connect when you're in range of a partner network at each destination, not in open water.
How to set up your Caribbean eSIM
Setup takes about two minutes. Confirm your phone supports eSIM (iPhone XS from 2018 and newer, most Android flagships from 2020), choose your Caribbean plan, and pay with card, Apple Pay, or Google Pay — your QR code arrives by email within seconds. Install it on Wi-Fi before you fly via Settings → Cellular → Add eSIM (iPhone) or Network & Internet → SIMs → Add eSIM (Android). It connects automatically when you reach your first island and works across the others on the coverage list — no reinstalling at each stop. Install it at home so you're ready the moment you land.
How much data do you need for a Caribbean trip
Most beach holidays are light on data. For maps, messaging, and email, around 300 MB a day is plenty, so a 3–5 GB plan covers a week comfortably. Add social media, beach photos, and music and you'll want closer to 700 MB a day; a 10 GB plan suits a longer or multi-island trip. Heavy streamers and anyone tethering a laptop should size up. On a cruise, remember you'll only have coverage while in range of land, so plan data around your port days — and you can top up mid-trip if you run low.
Hotspot, calls, and island-hopping
Your Caribbean eSIM roams across the coverage list, so you stay connected as you move between islands — no swapping SIMs at each stop. Every plan includes free mobile hotspot, so you can tether a laptop or share with travel companions, usually far faster than resort Wi-Fi. As a data-only eSIM there's no local number, but that rarely matters: WhatsApp, FaceTime, Messenger, and Google Meet handle calls and messages over data, and your home number stays reachable on your primary SIM. One plan covers the whole island run instead of a new SIM — or pricey Wi-Fi — at every stop.
Short trips vs. longer Caribbean journeys
For a week at one resort, a small 3–5 GB plan on a 7-day validity is usually plenty. For a multi-island trip or a longer stay, a 10 GB or larger plan gives you room to navigate and share freely across every stop. Because Flysimio plans give you six months to activate, you can buy before you leave and the validity only starts when your eSIM first connects in the region. There's no contract and nothing to cancel — the plan simply ends when it's done, and you can top up or rebuy for your next island escape.
