No. The Tobago Cays Marine Park has no cellular coverage from any carrier. Guides carry VHF radio for safety. Download offline maps, tide charts, and any sailing waypoints before leaving Union Island, and plan to reconnect when you return to a covered anchorage.

Yes near each port, intermittent mid-channel. Admiralty Transport and Bequia Express routes hold cellular for the first few minutes out of Kingstown and the last few minutes approaching Port Elizabeth. The middle stretch fades to 3G or drops entirely. Send messages before you lose signal.

Yes. Flow and Digicel both cover the main village, Basil's Bar, and the airstrip with 4G. Most villa properties stay within range, though the northern beaches (Endeavour Bay, Britannia Bay) can drop to 3G. Coverage is reliable enough for rideshare apps and restaurant bookings.

Three to five gigabytes covers maps, WhatsApp, ferry schedules, and occasional photo uploads. If you plan to video-call or stream music on every ferry ride, budget seven to ten gigabytes. Offline map downloads and cached playlists cut usage significantly on the outer Grenadines where coverage is patchy.

Yes, wherever you have 4G or 3G coverage. WhatsApp voice and video calls work across Kingstown, Bequia, and Mustique. The outer Grenadines and mid-ferry stretches may drop calls when signal fades. Regular cellular voice calls cost more, so stick to WhatsApp or Signal when data is available.

Both carriers offer 3G in Clifton (the main settlement) and near the airstrip. Coverage thins quickly outside the village, and neither network reaches the Tobago Cays. The eSIM hands off between them automatically, so you get whichever signal is stronger at your location without manual switching.

Yes. SVG Taxi Co-op and informal rideshare groups use WhatsApp for bookings, so any data connection lets you arrange pickups in Kingstown or Bequia. The app needs live data to confirm your location and share driver details. Coverage is reliable in town; pre-arrange rides if heading to remote beaches.

Weak signal at the parking area, none at the crater rim. Both Flow and Digicel fade as you climb above the trailhead. Download trail maps, share your itinerary with your hotel, and carry a charged phone for emergencies. The eSIM reconnects automatically when you return to the parking zone.

Log into your esima account (web or app) and purchase an additional data bundle. The top-up applies to your existing eSIM profile within minutes, no need to install a new QR code. You can top up from anywhere with Wi-Fi — hotel, café, or airport lounge.

A local Flow or Digicel SIM costs roughly the same in data terms, but you need to visit a shop in Kingstown with your passport, wait for activation, and top up in XCD cash if the plan expires. The eSIM installs before you leave home, activates on landing, and lets you keep your primary number active for banking codes and two-factor texts.

Yes, 3G in the main village and near the airport. The Canouan Estate resort area has coverage, but the windward beaches and the interior lose signal. Download offline maps before exploring beyond the main road. The eSIM reconnects when you return to a covered zone.

Yes. Hotspot tethering is enabled by default on esima eSIMs, so you can share your connection with a laptop, tablet, or travel companion. No extra fee, no throttling on the first few gigabytes. Useful when hotel Wi-Fi is slow or you need to work from a villa on Bequia.

Yes. Flow and Digicel both run 4G along the Leeward Highway resort corridor, including Buccament Bay and the properties south toward Layou. Signal holds steady at the beach clubs and dive centers. Coverage fades inland toward the Vermont Nature Trail, so download maps before hiking.
