Saint Vincent and the Grenadines eSIM

No. Carriacou and Petite Martinique sit at the southern end of the Grenadines chain, but they belong to Grenada, a separate country, and the boundary runs just south of Union Island and Petit St Vincent. Charter yachts and ferries often cross it, sometimes on the same day as a Tobago Cays visit, and there is a customs and immigration step at the border. Read the destination list on the offer, and either choose one that names both countries, or carry a separate plan for the Grenada leg.

By ferry or small plane. Passenger and car ferries run from Kingstown to Bequia several times a day, taking about an hour, and other services continue further south to Canouan, Mayreau and Union Island on less frequent schedules. Small planes link St Vincent with Bequia, Canouan, Mustique and Union Island. Timetables change with the season and the weather, so confirm departures close to the date and save tickets, piers and the next accommodation address offline.

When access is open, yes, with a guide. The volcano last erupted in April 2021, and access to the summit trails has since depended on the current alert level and on repairs to the routes. The classic hike climbs from the windward side through forest and over loose volcanic ground to the crater rim, and it takes a good part of a day. Check the current status with local authorities and guides before planning, start early and save the guide's contact offline.

Expect it to vary. Near the larger islands and busy anchorages a phone may find a signal, but between islands and at remote anchorages such as the Tobago Cays it may not, and the result depends on the handset, the plan and the exact location. Treat data as a convenience rather than a safety tool on the water: download the itinerary, port contacts and weather information before leaving the marina, and use the yacht's own navigation and communication equipment for anything that matters.

Mustique is a privately managed island known for its villas, and access is controlled. Most guests arrive by small plane or yacht as part of a villa or hotel booking, and visiting yachts can usually come ashore at Britannia Bay under the island's rules. There are only a few public places, so plan your visit through your charter skipper or accommodation. Because services are limited, save the arrangements, contacts and return details offline before leaving the main islands.

The Atlantic season runs from 1 June to 30 November, and Hurricane Beryl in July 2024 showed that storms can strike early, causing severe damage on Union Island and other southern Grenadines. Many charter companies and hotels adjust their seasons around this period. Choose flexible bookings for summer and autumn, follow official forecasts in the days before travel, and check that the businesses on your route are open, especially on the smaller islands.

The open water between the Grenadines, the far side of the reefs and the steep valleys of St Vincent are where reception is most likely to fade, and what a handset finds varies with the device, the plan and the exact spot. When you are ashore again, check that the travel line is switched on, selected for mobile data and has data roaming enabled, then restart the phone if it stays offline. Save ferry tickets, charter plans and accommodation details offline before each crossing.

No. Horizon fixed-data plans have no throttling. There is no daily limit that slows you down, so you can use your whole plan in one day if you need to. Your speed depends on the local network, your signal and how busy the network is. When your data allowance is used up, the plan stops rather than slowing down.

Yes. We always refund the full amount you paid when you request it, whether your eSIM is unused, partly used or fully used. There is no time limit for requesting a refund.
