Let PlanPilot™ AI Find Your Best 5G eSIM for Dominica

Official Languages: English

English Is the Official Language and Is Used Everywhere in Government, Business and Daily Life. Kwéyòl, a French-Based Creole, Is Also Widely Spoken, Especially among Older and Rural Residents, but Every Visitor-Facing Situation Works Fine in English Alone

Mobile Network: 4G Coverage Is Solid along the Populated West Coast, in Roseau, Portsmouth and around the Main Airport, but the Mountainous Interior — Rainforest, National Parks, the Cross-Island Roads — Drops to Patchy 3G or No Signal at All for Long Stretches. Plan Any Hike Assuming You Will Lose Signal

Roaming/SIM/eSIM: Roaming Is Convenient for a Short Trip If Your Home Plan Covers the Eastern Caribbean, Though Rates Can Be Steep Otherwise. A Local Physical SIM Is Usually Cheapest for a Longer Stay and Gets You a Local Number, but Needs an Unlocked Phone and an in-Person ID Check. An eSIM Is the Easiest Way to Land Already Connected. Whichever You Choose, Download Offline Maps before Heading into the Rainforest, Because Coverage Fades Fast Once You Leave the Coast

Cards Are Accepted at Hotels, Larger Restaurants, Supermarkets and Tour Operators, Especially around Roseau. Cash Is Still Needed for Small Shops, Roadside Vendors, Rural Guesthouses and Local Transport. US Dollars Are Widely Accepted Too, but Change Usually Comes Back in East Caribbean Dollars, so Carrying Some Local Cash Is Practical

Some Hotels and Restaurants Already Add a 10 Percent Service Charge, so Check the Bill before Tipping Again. Where No Service Charge Is Added, 10 to 15 Percent for Good Restaurant Service Is Standard. Small Tips for Taxi Drivers, Hiking Guides and Hotel Staff Are Appreciated and Often Make Up a Meaningful Part of Their Income

Plug Type: Type D and Type G

Voltage: 230 V, 50 Hz

Adapter: Visitors from North America Need a Plug Adapter, and Often a Step-Down Transformer Too, since the Island Runs on 230 V. Phone and Laptop Chargers Are Usually Fine Because They Auto-Switch, but Check the Label on Any Hairdryer, Shaver or Kettle — Most North American Ones Will Not Work Here at All
