eSIM Saint Vincent and the Grenadines

• St Vincent: Kingstown, the leeward coast towards Layou and the windward side around Argyle International have FLOW 4G/LTE. Heading north up either coast, it gets quieter past Georgetown or Chateaubelair, and the slopes of La Soufrière are unreliable.
• Bequia: good around Port Elizabeth and Admiralty Bay, with Lower Bay and Princess Margaret Beach mostly covered.
• Mustique and Canouan: signal around the settlements and resorts; villas tend to lean on their own Wi-Fi.
• Union Island: Clifton is covered, including the harbour where charter boats clear in and out.
• Tobago Cays: a protected marine park of uninhabited cays and reef. One bar is the best you’ll see, and often there’s nothing.

Connects to FLOW, operated by Cable & Wireless in St Vincent and the Grenadines, on fast 4G/LTE. No other network is used. Esimy doesn’t throttle, so real speed comes from the signal and the handset. Down the Grenadines, that signal comes from masts on the inhabited islands. Between them, or at anchor off an empty cay, it weakens and then drops, and out on open water you should plan on having nothing.

Data is dearer in the Caribbean than in Europe, so don’t overbuy for a short trip.
• 1–3 GB: a cruise call in Kingstown, or a week on a charter yacht, where you’ll be out of range a fair bit anyway
• 5–10 GB: one or two weeks between St Vincent and Bequia, with maps, WhatsApp and calls home in the evenings
• 20 GB: a month or more, or a long villa stay with the hotspot running your laptop

Kingstown’s Botanic Gardens are among the oldest in the Americas, and one breadfruit tree there descends from the plants Captain Bligh brought in 1793. La Soufrière, which last erupted in 2021, is a proper climb from the windward trailhead near Rabacca. Over on the leeward coast are Dark View Falls and Wallilabou Bay, where Pirates of the Caribbean was filmed. Then come the islands. Bequia has Port Elizabeth and Princess Margaret Beach, Mustique has sundowners at Basil’s Bar, and Mayreau has Salt Whistle Bay. Off Baradal in the Tobago Cays, you can snorkel with turtles.

Google Maps covers St Vincent’s roads well enough, but they’re narrow and steep and you drive on the left, so save the map offline before heading north. Minibuses leave from the Kingstown terminal and run along both coasts, usually with the music turned up. Fix taxi prices before you get in, as there are no meters. Ferries to Bequia leave Kingstown several times a day and take about an hour, and it’s best to check the day’s sailings locally rather than trust an old timetable. Charter skippers, water taxis and the vendors who come alongside in the anchorages mostly work by WhatsApp or VHF. You’ll pay in Eastern Caribbean dollars, though US cash is widely taken.

Roam-like-at-home deals don’t stretch this far, so a UK or EU tariff will charge roaming here, and US carriers usually bill by the day. Install the Esimy eSIM at home. On arrival, switch Data Roaming on for the eSIM (not for your home SIM) and pick the eSIM for mobile data. Many flights to Argyle connect in Barbados; our Barbados eSIM is the separate plan for that stop. Sailing south from Union Island to Carriacou means entering Grenada, which this plan doesn’t cover.
