Grenada eSIM guide: mobile data for travellers
Grenada, the "Spice Isle", lies at the southern end of the Windward Islands, not far north of Trinidad. The country is made up of three inhabited islands: Grenada itself, with the harbour capital of St George's and the long sweep of Grand Anse Beach; Carriacou, quieter and smaller, to the north; and tiny Petite Martinique beside it. Visitors come for beaches, snorkelling and diving at the underwater sculpture park, rainforest hikes around Grand Etang, waterfalls, nutmeg and cocoa estates, and sailing through the Grenadines.
A Spidot eSIM gives you mobile data in Grenada without buying a local SIM. You install it before you travel, switch it on when you land and keep your own SIM for calls and texts. This guide explains the options, how much data to plan for, and what to expect from coverage on the main island, in the interior and on Carriacou.
eSIM, roaming or a local SIM in Grenada
Most visitors to Grenada arrive from the UK, North America or other Caribbean islands. Each of these groups faces a slightly different roaming picture.
Roaming with your home SIM
Some operators include parts of the Caribbean in their travel add-ons, while others charge separately for each island. Grenada is not covered by EU roaming rules, and US and Canadian plans differ widely in what they include. Check your operator's terms for Grenada specifically before you go, particularly if you are island-hopping, because terms can vary from one island nation to the next.
A Grenadian prepaid SIM
Local SIMs are sold in St George's, at shops and sometimes at the airport. They can make sense for long stays or sailors spending a season in the area. For a short holiday, buying and registering a SIM takes time you might rather spend on the beach.
A Spidot eSIM for Grenada
A Spidot eSIM adds a separate data line. You buy a Grenada plan online, receive the QR code by email straight after payment and install it at home. Plans start from $14.90. Most plans are data-only, without a local number; if you need to call restaurants, taxi drivers or tour operators on local numbers, see our Data + calls plans.
How much data to plan for
A Grenada holiday usually involves maps, messaging and lots of photos, with heavier use if you work or stream in the evenings. Rough estimates:
- Maps and navigation: a few megabytes per hour, useful on winding island roads.
- Messaging: light; taxi drivers, dive shops and guides commonly arrange things by WhatsApp.
- Photo and video sharing: moderate to heavy, especially underwater footage and sunset videos.
- Video calls: typically several hundred megabytes per hour.
- Streaming: heavy, often a gigabyte or more per hour of HD video.
Typical choices
A week at Grand Anse or Morne Rouge with good hotel Wi-Fi fits a small fixed data plan. A longer trip, a self-drive holiday around the island, or a visit to Carriacou where Wi-Fi may be simpler, is more comfortable with a larger plan.
Remote workers and long-stay sailors may prefer an unlimited plan, keeping in mind that speed may slow after heavy use, or a no-expiry plan for repeat visits. You can check how much data is left and add more data whenever you need.
Before you go
Install your eSIM at home over Wi-Fi. First check your phone supports eSIM and is carrier-unlocked. Then follow the install guide for iPhone, Samsung or Pixel. Label the line "Grenada", keep your home SIM as default for calls and texts, and set the Spidot line for mobile data.
- Install the eSIM a day or two before departure.
- Download offline maps of Grenada and Carriacou.
- If you are island-hopping, install a plan for each island nation you will visit and label each one clearly.
- Bring a waterproof pouch for boat trips and beach days.
- Turn off data roaming on your home SIM before you land.
Arriving in Grenada
International flights land at Maurice Bishop International Airport at Point Salines, on the south-western tip of the island. It is close to Grand Anse, Lance aux Épines, True Blue and other hotel areas, and a short drive from St George's. Cruise ships dock in St George's, and yachts arrive at marinas around the south coast and in Carriacou.
On arrival, select the Spidot line for mobile data and turn on data roaming for it; our data roaming guide shows where the setting is. It can take a minute or two to register. If it does not connect, switch flight mode on and off.
Leaving the airport
Taxis wait outside arrivals, and many hotels arrange transfers. Having data lets you message your host, check the route and confirm the price of the taxi before you set off. If you are renting a car, data also helps you find your way out of the airport onto the south coast roads.
Arriving by yacht
Sailors often arrive from St Vincent and the Grenadines in the north or from Trinidad in the south. Switch your mobile data line to the Grenada plan once you have arrived, and keep the previous island's plan installed for the return leg.
Coverage on the island, in the interior and on Carriacou
In St George's, Grand Anse, the south coast and the larger towns such as Grenville, Gouyave and Sauteurs, mobile data generally works as you would expect. The main coastal road around the island is usually covered for much of its length.
Grenada's interior is mountainous and forested, which creates some weaker areas:
- Grand Etang Forest Reserve: the road through the centre of the island climbs into rainforest, and signal can fade on the bends and on hiking trails.
- Waterfalls: trails to the Seven Sisters falls and other inland waterfalls run through valleys where signal may be weak.
- The north and east coasts: quieter areas around Levera and parts of the windward coast can have patchier coverage between villages.
- Carriacou and Petite Martinique: the main settlements are usually covered, but quiet beaches and hills may have weaker signal.
- At sea: on boat trips and sailing passages between islands, signal fades as you move away from the coast.
Near neighbouring islands
Carriacou and Petite Martinique are close to Union Island and other islands of St Vincent and the Grenadines. Near the northern islands, your phone may occasionally see a network from across the water. If data behaves unexpectedly, check which network you are on.
Flow are among the networks your Spidot plan can use in Grenada.
Data on buses, ferries and road trips
Grenada's public transport is mainly by minibus. The buses are numbered by route, start from the bus terminal in St George's and stop on request along the way. They are an easy and lively way to travel, and a map helps you know when to ask the driver to stop.
Driving
Driving is on the left. Roads are narrow, steep and winding, especially in the interior and the north. Navigation apps are useful, but local drivers often know faster or easier routes. Download offline maps and set your route before entering the mountains.
Ferries and short flights to Carriacou
Carriacou is reached by ferry from St George's or by a short flight. On the ferry, signal usually holds near both coasts and may drop in between. Download music, podcasts or maps before you board.
Sharing data with a hotspot
If your villa or apartment has slow Wi-Fi, your phone's personal hotspot can share your Spidot data with a laptop or tablet. It uses whichever line is set for mobile data, so make sure that is the Spidot line.
Pause automatic updates and photo backups on connected devices, and check your remaining data now and then. If you plan to tether every day, consider a larger or unlimited plan.
Using public Wi-Fi safely
Hotels, beach bars and restaurants often offer Wi-Fi. It is convenient but not always secure.
- Use your eSIM data for banking, card payments and important logins.
- Ask staff for the exact network name.
- Turn off automatic joining of open networks.
- Update your phone and apps before travelling.
Practical tips for Grenada
A few details that make a data connection more useful:
- Currency: Grenada uses the Eastern Caribbean dollar (XCD). US dollars are widely accepted in tourist areas, often with change given in local currency. Cards are accepted at hotels and many restaurants; carry cash for buses, markets and small shops.
- Language: English is the official language.
- Taxis: agree the fare before you set off, and keep the driver's number for the return trip.
- Diving and snorkelling: the underwater sculpture park at Molinere Bay is a popular trip. Keep your phone in a waterproof pouch on the boat.
- Weather: the Caribbean hurricane season runs roughly from June to November. Keep weather apps installed and follow local advice if a storm is forecast.
- Spice estates: visits to nutmeg processing stations, chocolate makers and rum distilleries are popular. Many are in the countryside, so download maps before you set off.
Grenada on a multi-country trip
Grenada is often combined with St Vincent and the Grenadines to the north, especially by sailors, and with Trinidad and Tobago to the south. Flights also connect Grenada with Barbados and St Lucia.
The simplest approach is one eSIM per country. Most eSIM phones store several eSIMs, so install a plan for each island nation before your trip, label each clearly, and switch the mobile data line when you arrive. Only the selected line uses data.
