The Isle of Spice is actually three islands — Grenada, Carriacou, and Petite Martinique — and coverage is not the same across all of them. Two solid carriers on the mainland, and a genuinely useful split emergency number worth knowing.

⚡ POWER TIP
Also visiting Barbados, Saint Lucia, or Trinidad and Tobago on the same trip? A regional Caribbean eSIM covers all of them under one plan, which works out simpler than buying single-island eSIMs for each stop.
✅ VPN FULLY LEGAL
No restrictions on personal VPN use in Grenada. Use one freely on public WiFi, in hotels, or anywhere else — it is simply good practice, not a legal grey area. See our travel security note below.

// Network operators
Digicel
The stronger of the two networks, with wider reach across the island including St. George's, Grand Anse, and Grenville. Most travel eSIM providers route through Digicel in Grenada.
Flow
The other operator on the island, with solid 4G in the main towns and tourist areas. A perfectly reasonable choice if you are sticking mainly to St. George's and the southwest coast.
// Coverage by area
St. George's, Grand Anse & Grenville
4G coverage is strong and consistent around the capital, the famous Grand Anse beach strip, and Grenville on the east coast. This is where most visitors spend the majority of their trip.
Carriacou & Petite Martinique
Grenada's two sister islands have noticeably thinner coverage than the mainland, given their small populations. Both are covered, but do not expect the same consistency you get around St. George's.
💡 Why Grenada is really three islands
The State of Grenada consists of Grenada itself plus Carriacou and Petite Martinique, part of the Grenadines chain. Digicel and Flow both serve all three, but tower density naturally follows population — so the mainland gets the strongest, most consistent signal, while the smaller islands see more variability.
// Practical tips
The underwater sculpture park has great surface signal
Molinere Bay, home to the world's first underwater sculpture park, sits close enough to St. George's that boats and the shoreline keep solid 4G. Obviously nothing works below the surface, but topside connectivity is not an issue.
911, except for ambulance
911 covers police and fire, but ambulance in Grenada is a separate, older-style number: 434. Coast guard can also be reached on VHF Channel 16. Worth saving 434 specifically, since 911 will not route you to an ambulance here.
Physical SIMs need a passport
Buying a physical Digicel or Flow SIM at Maurice Bishop International or a retail store means bringing your passport for ID. eSIM tourist plans skip this entirely — install before you fly and land already connected.
// Travel security
Protect your identity abroad
Hotel and resort WiFi in Grenada carries the same everyday risk as anywhere else. Avoid logging into banking or sensitive accounts on public networks. Use your eSIM data instead where you can — and since VPNs are unrestricted here, running one on public WiFi is genuinely worth doing.
Alternative ID for travel
When signing up to local apps and services — convenience store WiFi portals, rail booking sites, loyalty apps — consider using a disposable identity and email address to keep your real details private. Surfshark Alternative ID is built for exactly this use case.
