Yes, but expect 3G speeds across most of both islands. Digicel has slightly better interior coverage on Carriacou; Flow is stronger near the Hillsborough ferry dock. Petite Martinique has patchy 3G with occasional dropouts. Download maps and any large files before the ferry from the main island.

The sculpture park is within 4G range from shore, so the eSIM works if you are snorkelling independently. Premium dive-boat operators sometimes carry on-board Wi-Fi for the trip out, but most smaller boats do not — the eSIM is your reliable option.

The visitor centre and the lake viewpoint have LTE from both networks. The hiking trails deeper into the rainforest — especially the route to Concord Falls — drop to single-bar coverage or lose signal entirely. Download offline maps before you leave Grand Anse.

A typical week — Google Maps navigation around the island, WhatsApp chats and voice calls, occasional photo uploads — runs about three to five gigabytes. If you are streaming video back to your hotel each evening or uploading dive footage, budget eight to ten gigabytes. Carriacou's 3G speeds make streaming impractical.

Yes. The eSIM is data-only, so traditional voice calls through the phone dialler will not work, but WhatsApp voice and video calls run over the data connection at no extra cost. Quality is reliable across St. George's and Grand Anse; expect occasional chop on Carriacou's 3G.

Both deliver 4G across St. George's, Grand Anse, and the cruise port. Digicel has slightly better reach into the interior hills and on Carriacou; Flow is stronger along the main coastal roads and near the airport. The eSIM switches between them automatically, so you get the stronger signal at each location.

Yes. Both networks handle the August Carnival surge, though you may see brief congestion in St. George's during peak parade hours. Having the eSIM live before you arrive means you can confirm accommodation and transport through WhatsApp rather than hunting for hotel Wi-Fi when every guesthouse is full.

Yes, across the main island. St. George's, Grand Anse, Grenville, and the coastal roads all have reliable 4G for turn-by-turn navigation. The interior mountain roads between Grand Etang and Concord Falls thin out to single-bar LTE — download an offline map before heading inland.

Grenada has no app-based rideshare — taxis are negotiated in person or by phone. Most Grand Anse restaurants accept card, but smaller vendors near Grenville and the Saturday market in St. George's prefer cash in Eastern Caribbean dollars. The eSIM keeps you online to confirm bookings and check exchange rates.

A physical SIM from the Digicel or Flow counter at Maurice Bishop International costs roughly the same per gigabyte but requires a passport photocopy, a registration form, and a trip back to the shop or a top-up kiosk if you run dry mid-week. The eSIM activates in the arrivals hall and lets you add data from the app without leaving your beach chair.

You will have 4G signal for the first fifteen minutes out of St. George's, then coverage drops to 3G or disappears entirely mid-crossing. Signal returns as you approach Hillsborough on Carriacou. The ferry trip is about ninety minutes — download any maps or content before boarding.

Yes. Hotspot is enabled by default with no extra fees. Useful if you are working remotely from a Grand Anse hotel or sharing the connection with a travel partner whose phone does not support eSIM. Expect slower tethering speeds on Carriacou's 3G network.

Yes. Both Digicel and Flow have full 4G coverage across Maurice Bishop International. Scan the QR code in the arrivals hall; by the time you reach the taxi rank, the profile will be live and you can pull up maps for the drive to your hotel.
