The Caribbean is outside UK and EU roaming bundles. Recently published UK rates are about £7 a day on O2, £7.50 for a 24-hour pass on EE and £8 a day on Vodafone. Rogers lists a Travel Pass for Mexico and the Caribbean from CA$50 for 3 days to CA$190 for 14 days. On a cruise ship it is worse: ships use their own maritime network, which sits outside roaming allowances and day passes. A local eSIM installed before you fly gives you fixed-price data on land and in port. GleeSim sells one plan per island, managed in one WhatsApp chat.
Each GleeSim Caribbean plan covers one island, such as Barbados, St Lucia or the Bahamas. We do not sell a single plan for every island, so you only pay for where you are going.
An eSIM works on land and in port, not at sea. Ships run their own maritime network, so we tell you when to switch the eSIM on and when to switch roaming off.
Flying with BA to Barbados, or on a TUI or Flair package? Install the eSIM at home and switch it on when you land. Your flight and hotel do not affect it.
A local SIM means finding a shop and handing over your passport. Your eSIM is installed at home and ready when you arrive.
GleeSim runs as a second data line. Your own SIM stays in the phone, so your WhatsApp number, bank codes and family groups stay the same.
Low on data on St Lucia or in Nassau? Send one message and we add data to the same eSIM. No new QR code and no shop visit.
Each plan works on one island only. Pick your island first. Use code GLEE10 when you order on WhatsApp for an extra 10% off. Not sure which island plans you need for a multi-island trip? Send us your route on WhatsApp.

Answers to the questions travellers ask us most before a Caribbean trip or cruise.
The best Caribbean eSIM 2026 is one you install at home that matches the island you are visiting. GleeSim sells one plan per island, from $37.36 for Jamaica to $53.24 for the Bahamas for 5GB. Pick the island, scan the QR code before you fly and switch it on when you land. For a multi-island trip, see the answers below on how to cover more than one island.
Not at the moment. GleeSim Caribbean plans are per island, so there is no multi-island Caribbean eSIM one plan that covers every island. If you are visiting two or three islands, tell us your route on WhatsApp and we will suggest the cheapest set of plans, all managed in the same chat.
No. Each GleeSim plan works on one island only, for example Barbados, St Lucia, the Bahamas or Grenada. Coverage does not carry across the sea to the next island. If you are island hopping, buy a plan for each island where you need data and install them before you fly.
For the best eSIM for island hopping Caribbean routes, buy a plan for each island where you will spend more than a day. You can install several eSIMs on one phone and switch between them in settings. On islands where you only stop for a few hours, use offline maps and WiFi in cafes to save money.
The best eSIM for Caribbean cruise 2026 trips is a plan for the island where you spend your longest port day, plus offline maps for the others. The eSIM works on land and in port, but not at sea. Buy a plan only for ports where you plan to use data, because plans are per island.
For the hours you are on shore, a Caribbean eSIM vs cruise ship WiFi comparison favours the eSIM, because ship WiFi only works on board. On board, only the ship's WiFi works. Published ship WiFi packages cost about £14 to £20 a day on P&O Cruises and around $33 a day on Royal Caribbean, and prices vary by sailing.
A Caribbean eSIM is far cheaper than roaming at sea. Ships use a satellite or maritime network that sits outside roaming allowances and day passes, and some UK networks charge about £5 per MB there. A GleeSim eSIM only connects to local networks on land and in port, so it can never run up a maritime bill.
To avoid maritime roaming charges, turn on airplane mode or switch off data roaming on your home SIM before the ship leaves port. Then use the ship's WiFi package if you need it. Phones can latch on to the ship's own network at sea without warning, so check that roaming is off for every sea day.
No. Ships use their own maritime network, and an eSIM works in port only. Once the ship is out of range of the island networks, your eSIM has no signal. Use the ship's WiFi package at sea and switch your eSIM back on when you dock.
Yes. Turn off data roaming on your home SIM, and switch your GleeSim eSIM line off as well, before the ship leaves port. That stops your phone connecting to the ship's maritime network and charging you at sea rates. Turn the eSIM back on when you dock at the next island.
On a 7-night Caribbean cruise you only use the eSIM on port days, so 1GB to 2GB per port day covers maps, messages and photos. Plans are per island, and the 5GB plan suits the island where you spend your longest day. Download offline maps for the other ports and use the ship's WiFi package at sea.
Yes, for the ports. An eSIM for Marella Caribbean cruise itineraries or an eSIM for MSC Caribbean cruise sailings works the same way. It connects on land and in port, not at sea. Tell us your ports on WhatsApp and we will say which islands have a plan.
A Caribbean eSIM is usually cheaper than roaming for a week or more. EE lists a 24-hour pass at about £7.50 in its Zone 3, which includes Jamaica, and the data is capped at 500MB a day. Seven days of EE roaming is about £52. A GleeSim 5GB island plan costs $37 to $53 once. Check your own plan's country list, because prices change.
A Caribbean eSIM is usually cheaper than Rogers roaming for a week or more. The Rogers Travel Pass for Mexico and the Caribbean is listed at CA$50 for 3 days, CA$100 for 7 days and CA$190 for 14 days. A GleeSim 5GB island plan costs $37 to $53 once and lasts up to 30 days. Check Rogers for the current price.
Yes. A Caribbean eSIM Christmas New Year 2026 order works the same as at any other time of year. Order a few days before you fly, install it at home, and switch it on when you land. Flights are busy at Christmas, so order early if you need several QR codes for family.
Yes. A Caribbean eSIM buy on WhatsApp works like any other order. Message us, pick your island, and your QR code arrives in the chat in about 60 seconds. Install it at home before you fly. You don't need an app or an account.
The best eSIM for Barbados 2026 is one you install at home. The Barbados 5GB, 30 Days plan at $37.71 suits most people. An eSIM for Barbados BA holiday packages works the same as on any trip. Install it before you fly and switch it on when you land at Grantley Adams Airport.
Yes. The St Lucia eSIM plan costs $39.42 for 5GB and $78.85 for 10GB, both for 30 days. The Grenada eSIM plan costs $41.14 for 5GB and $82.27 for 10GB. Install your QR code before you fly and switch it on when you land.
Yes. The Bahamas eSIM plan costs $53.24 for 5GB and $106.49 for 10GB, both for 30 days. It works on land and in port, so it suits a Nassau port day or a stay on Paradise Island. It does not work at sea.
Yes. A Jamaica eSIM from UK holidaymakers works like an order from anywhere else. The Jamaica 5GB, 15 Days plan costs $37.36. You can see the details on our Jamaica eSIM page. Order on WhatsApp, install the QR code at home and switch it on when you land.
For a week or more, a Punta Cana eSIM is usually cheaper than the Rogers Roam Like Home Travel Pass. The Rogers pass for Mexico and the Caribbean is listed at CA$100 for 7 days. The GleeSim Dominican Republic 5GB, 30 Days plan costs $47.44 once. Check Rogers for the current price.
Most Punta Cana resorts include free WiFi, but it is often limited to the lobby and rooms and can be slow in the evening. It rarely reaches the beach. An eSIM gives you your own connection wherever there is a mobile signal.
Yes. A Punta Cana eSIM from Canada works like an order from anywhere else. The Dominican Republic 5GB, 30 Days plan costs $47.44. Order on WhatsApp, install the QR code before you fly from Toronto or Montreal, and switch it on when you land.
Digicel and Flow are the two main mobile networks across many Caribbean islands. Coverage differs by island and by beach, and some islands, such as the Bahamas, have other local operators. Your eSIM connects to the network available to it, and you can ask us on WhatsApp which one your island plan uses.
Send us a WhatsApp message and we add more data to the same eSIM within minutes. You don't need a new QR code or a shop.
