eSIM for Grenada

The Spice Isle scents itself with nutmeg drying along roadsides in Gouyave, while Grand Anse beach curves toward St. George's pastel harbor and Annandale Falls pools beneath rainforest. Divers drop into the Underwater Sculpture Park off Molinere Bay. You'll use data to book catamaran trips to Carriacou, message guesthouse owners in Lance aux Epines, and pull up navigation for the serpentine drive across the island's interior.

How to install your Grenada eSIM in 3 steps

Setting up data for the Spice Isle takes less time than clearing immigration at Maurice Bishop International.

1. Buy and receive your QR code. Choose a plan sized to your trip - from a short 1GB/7-day top-up to a fuller 20GB/30-day plan - and the eSIM QR code lands in your email within minutes of checkout.
2. Install while you still have wifi. Before you fly, open your phone's eSIM settings, scan the QR code, and let the profile install. Label it "Grenada" so it's easy to pick out from your home line once you're on the ground.
3. Land and switch on data roaming. Once you touch down, enable the Grenada eSIM as your data line and turn on data roaming. Your phone should pick up a Flow or Digicel LTE signal around St George's or Grand Anse within moments, no kiosk queue required.

Coverage in Grenada

Two networks handle mobile data on the island: Flow (Cable & Wireless) and Digicel. Flow has the wider reputation for reach, particularly strong through St George's and the coastal tourist zones, while Digicel runs a broadly similar urban footprint with competitive pricing. Neither operator has launched 5G in Grenada; 4G LTE is the working standard for data, and it's concentrated in urban centres and populated coastal stretches.

The main island's coverage is strongest right where most visitors spend their time: the Grand Anse resort corridor, the St George's Carenage waterfront, and the main transport routes linking them. Coverage thins out quickly once you head inland or up into the mountains, and it can be patchy around remote spice estates. Carriacou and Petite Martinique, the dependency islands reached by a roughly 90-minute ferry from the mainland, have notably more limited mobile coverage than the main island, so treat data there as a bonus rather than a guarantee.

For day-to-day sightseeing, an LTE connection around St George's, Grand Anse, and the main coastal road should feel dependable. It's the plantation tours and outer-island excursions where you'll want to plan around potential gaps rather than assume a constant signal.

Data needs by trip type

Usage level	Typical daily use	Suggested plan
Light	Around 300 MB/day - maps, messaging, occasional browsing between the beach and the Carenage	1GB / 7 days
Moderate	Around 750 MB/day - social media, navigation, some music or video calls home	3GB / 30 days or 10GB / 30 days
Heavy	1.5 GB/day or more - video streaming, video calls, working remotely from the resort corridor	20GB / 30 days

eSIM vs roaming vs local SIM in Grenada

Option	Cost	What to know
eSIM (data-only)	From £4.76, or £7.48 for the cheapest 1GB option	Installed before you fly, active the moment you land, no shop visit or ID check needed
Home carrier roaming	Around £7 a day with major US day-pass plans; T-Mobile's included global roaming plans tend to work out better value	Simplest option if you're only online for messages and maps, but daily fees add up over a week-long stay
Local Flow or Digicel SIM	A small purchase fee (roughly £3-£5 in local currency terms), plus a prepaid data bundle - Digicel's own roaming-style bundles run about £11 for 3 days or £21 for 7 days, and local prepaid data packages are typically priced from around £8 up to about £27	Passport or valid photo ID is required at purchase; no biometric fingerprint or device IMEI registration is needed. Available at the airport, retail stores, and operator kiosks island-wide

Practical connectivity tips

If your itinerary includes the ferry to Carriacou or Petite Martinique, download offline maps and messages in advance - mobile coverage on those islands is noticeably more limited than on the mainland, and travellers who need to stay reachable often carry a second SIM or line as backup for the crossing. The same applies to nutmeg plantation visits: estates like Belmont Estate and Dougaldston Spice Estate sit in rural areas where LTE can drop out, so don't rely on real-time navigation once you leave the main coastal roads.

Grenada's internet backbone runs through a single undersea cable, so a rare cable outage can affect connectivity island-wide, which is worth knowing if you need to stay online for work. Around St George's and Grand Anse, both Flow and Digicel LTE hold up well for everyday browsing, calls, and social media, so there's rarely a need to seek out wifi in the main tourist areas.
