The best eSIM for Dominica is a data plan sized to your days on the island, installed on Wi-Fi before you fly. A SimOptions Dominica eSIM does that: it runs on the Flow network in 4G/LTE, activates when you arrive in Dominica and comes in sizes from 1 GB for 3 days to 20 GB for 15 days. It has no phone number, so you call through WhatsApp or FaceTime. Staying longer or hopping to Guadeloupe or Saint Lucia? Our Caribbean eSIM covers Dominica too, with plans of up to 30 days.

Dominica or the Dominican Republic?
Many people searching for a Dominica eSIM are really going to the Dominican Republic. They are two different countries. Dominica, officially the Commonwealth of Dominica, is an island in the Eastern Caribbean known as the Nature Island (Discover Dominica: travel Dominica). Its phone area code is 767 (Discover Dominica: additional information).
A Dominica plan works in Dominica only. If your trip is to the Dominican Republic, buy a Dominican Republic eSIM instead.

What to look for in an eSIM for Dominica
- Coverage: check that Dominica is on the plan's country list. A Dominica plan suits a trip that stays on the island. Arriving by ferry from Guadeloupe or Saint Lucia? See the section on island hopping below.
- Data and days: both are on the plan page. A small plan fits a few days in Roseau. For a week or two with maps, booking apps and video calls, look at a bigger one.
- Speed: our Dominica plan details list 4G/LTE speed.
- A local number: our travel eSIMs are data-only. If you must call guides, taxis or guesthouses on a normal Dominican number, a local carrier fits better.
- Setup before you fly: you get a QR code by email and install it on Wi-Fi at home. Your phone must support eSIM and be unlocked (see how to check eSIM compatibility).
How much data do you need in Dominica?
These are the sizes on our Dominica eSIM page, with what each one lasts:
- Dominica 1GB and 3GB: 1 GB or 3 GB for 3 days. A cruise stop or a short visit.
- Dominica 5GB and 10GB: 5 GB or 10 GB for 7 days. A week with maps, messages and photos.
- Dominica 20GB: 20 GB for 15 days. Two weeks, with some video.
Staying longer than 15 days? The Caribbean plans with Dominica in their coverage last 30 days (3 GB, 5 GB or 10 GB). If you run out of data, top-ups are available. Not sure how much you need? Pick the bigger size. Our guide to eSIM data plans shows how to estimate it, and how to reduce data usage abroad helps you make it last.
Which network does a Dominica eSIM use?
Our Dominica plans run on Flow. You don't pick the network yourself: the plan's settings use automatic network selection, with data roaming turned on for the eSIM. The eSIM activates by itself when you reach Dominica, and you have 1 year to start using it.
Signal still varies by place, whichever eSIM you use. Dominica is mountainous and covered in rainforest, so expect weak or no signal on some trails. The hike to the Boiling Lake, for example, takes 3 to 4 hours each way through the Valley of Desolation, and it must be done with a licensed local guide (Discover Dominica: the Boiling Lake). Download offline maps before you head out (Google Maps: download areas offline).
Local SIM or travel eSIM?
Dominica's tourism board names two major mobile providers on the island: FLOW and Digicel (Discover Dominica: additional information).
- Digicel lists prepaid bundles with data and local calls on its prepaid page. To switch to Digicel, its page asks you to visit a store with a valid government-issued ID (Digicel Dominica: prepaid plans). The page does not mention eSIM, so ask in the store if your phone has no SIM tray.
- Flow is the network our Dominica eSIM uses. For a Flow line with a local number, see Flow Dominica and its stores.
A local line gives you a Dominican number, but you set it up in a store after you land. A travel eSIM is different: you buy it online, scan a QR code at home and have data as soon as you arrive.
Choose a local line if you stay a long time and need a Dominican number for calls. Choose a travel eSIM if you want data the moment you land at Douglas-Charles or step off the ferry in Roseau. You can keep your home number active next to it (Apple: Using Dual SIM with an eSIM), see how to set up a dual eSIM.
Travel eSIM or roaming with your home carrier?
Most readers of this guide come from the USA, the UK and Canada. Before you travel, check whether your home plan includes Dominica and what it costs per day or per gigabyte. Apple's advice is the same: check with your carrier whether international roaming is included or sold as a travel pass (Apple: Use eSIM while traveling). If it isn't included, a data-only travel eSIM is usually the simpler choice. We compare both in international roaming vs travel eSIM.
Which eSIM for Roseau, Portsmouth or the rainforest?
You don't need a different eSIM for each place. A Dominica plan covers the whole island, from the capital Roseau to Portsmouth on the northern coast and the trails of Morne Trois Pitons National Park, a UNESCO World Heritage Site (Discover Dominica). It activates when you arrive, so it works the same whether you land at Douglas-Charles Airport (DOM) in the northeast, about an hour from the capital, or at Canefield Airport (DCF), 15 minutes from Roseau (Discover Dominica: arriving by air).
The usual data uses on a Dominica trip are maps, messages, booking guides and tours, and checking the weather before a hike. These need little data, so a 10 GB plan may be enough for a week. Video calls, streaming and uploading waterfall videos use much more, so go for 20 GB on a two-week trip.
Island hopping to Guadeloupe, Martinique or Saint Lucia?
Ferries link Dominica with Guadeloupe, Martinique and Saint Lucia (Discover Dominica: arriving by sea). For a trip like that, look at our Caribbean eSIM. Its coverage list includes Dominica, Guadeloupe, Saint Lucia, Barbados, Antigua and Barbuda, Grenada, the Dominican Republic and more, and it uses Flow in Dominica too. Martinique is not on its list, so check the country list before you buy.

How do you get an eSIM for Dominica?
- Check your phone: it must support eSIM and be carrier unlocked. On iPhone, go to Settings > General > About and look for "No SIM restrictions" next to Carrier Lock (Apple: Unlock your iPhone).
- Buy and install on Wi-Fi: you get a QR code by email. Our install guide walks you through it.
- Turn on the eSIM when you land: turn on data roaming for the Dominica eSIM, and use it as your data line so your home line doesn't run up roaming charges. Our guide to the correct roaming settings for an eSIM shows how.
