eSIM Coverage Guide for Irish Travellers in the Caribbean
The Caribbean's mobile connectivity is dominated by two operators: Digicel and Flow (Liberty Latin America). Larger islands have solid urban 4G. Small uninhabited cays and remote beaches have no coverage.
Jamaica has reliable 4G from Digicel and Flow in Kingston, Montego Bay, Negril, and Ocho Rios. Tourist resort areas along the north coast are well-covered.
Barbados has good 4G in Bridgetown and south and west coast resort areas. Digicel and Flow are the main operators.
Trinidad and Tobago has solid 4G in Port of Spain from Digicel and bmobile. Tobago's main areas have functional coverage.
French Caribbean territories including Martinique and Guadeloupe have EU-standard 4G and 5G from Orange and SFR. These are among the best-connected islands in the Caribbean.
Note: EU Roaming Regulation does not apply in the Caribbean, including in Martinique and Guadeloupe despite being French territories. Your Irish carrier charges standard international rates in the Caribbean.

eSIM Travel Tips for Caribbean
Install Before Leaving Dublin
The Caribbean is a very long-haul destination from Dublin, typically connecting through London Heathrow, Amsterdam, or New York. Install your HelloRoam Caribbean eSIM before you depart. You land at your Caribbean destination and your phone connects straight away. No SIM shop, no fuss.
Download Offline Maps for Island Driving
Rental cars are common across the Caribbean and island roads can be remote. Download offline Google Maps or Maps.me for each island before you leave your accommodation. GPS works without signal so you can navigate coastal and mountain roads even without data.
EU Roaming Doesn't Apply in the Caribbean
Your Three IE, Vodafone Ireland, Eir, or GoMo plan's EU Roaming allowance applies only within the EEA. In Jamaica, Barbados, or any Caribbean island, standard international roaming rates apply. A HelloRoam Caribbean eSIM is a much more cost-effective option for your holiday data.
French Caribbean Islands Have Premium Coverage
Martinique and Guadeloupe are French overseas territories with Orange and SFR operating EU-standard 4G and 5G. Coverage quality is excellent. Despite being French territories, your Irish carrier's EU Roaming benefit does not apply here as they are outside the EEA roaming zone.
Emergency Numbers Vary by Territory
Emergency numbers vary across Caribbean territories. Jamaica: 119 police. Barbados: 211 police. Trinidad and Tobago: 999. The Bahamas: 919. Research and save the correct numbers for each island before leaving Dublin.
Network Coverage Across the Caribbean
The Caribbean mobile market is led by Digicel and Flow (Liberty Latin America). Both operate regional networks covering most populated islands.
Jamaica's Digicel and Flow compete with solid 4G in Kingston, Montego Bay, and resort areas. Barbados has Digicel and Flow on a small island with fairly complete tourist area coverage.
Trinidad and Tobago has Digicel and bmobile. Port of Spain has strong 4G. Tobago has adequate coverage in Scarborough.
The Bahamas has BTC and Aliv. Nassau has strong 4G. Out Islands have limited coverage.
French territories including Martinique and Guadeloupe have Orange and SFR operating EU-standard networks. US territories including Puerto Rico connect through AT&T and T-Mobile.

Cat
On a trip to Europe, my hotel Wi-Fi was so slow and outside Wi-Fi was unreliable. I couldn’t take it anymore so I got helloroam for a few days. It was tricky to set up correctly because of the primary settings (with my original number). But I reached out to their customer service via WhatsApp. Super responsive and helpful, with specific and clear steps to troubleshoot. Appreciate having 4G roaming instead of being stuck with in and out Wi-Fi during my trip!!
Rated 5 out of 5 by this reviewer
Very good experience! The eSIM was easy to set up and worked great in London. It was much cheaper than it would have been to use my own operator there.
