Network coverage in Grenada
FLOW (part of Liberty Latin America) is Grenada's primary mobile carrier, providing 4G LTE in St George's, Grand Anse, and along the main tourist roads. Digicel operates on the island but has lower market penetration for eSIM-compatible plans. FLOW serves the wider Eastern Caribbean region with consistent infrastructure across Grenada's three islands.
Most international eSIM plans use FLOW for Grenada.
Coverage analysis
FLOW 4G LTE covers St George's capital including the Carenage harbor, Grand Anse Beach (Grenada's main resort strip), and Maurice Bishop International Airport. The southwest tourist corridor from Grand Anse to Lance aux Épines has solid 4G. Concord waterfall and the Grand Etang rainforest interior have variable 3G.
The northern spice-growing parishes see 3G to 4G depending on elevation. Carriacou island (accessible by ferry from St George's) has FLOW coverage in Hillsborough but weaker signal in the interior.
Activation
Install your eSIM QR code before flying into Maurice Bishop International Airport (GND). FLOW registers your plan within minutes of landing. No SIM card queue needed.
Grenada is an English-speaking island making communication easy for most international visitors. iPhone XS or newer, Pixel 3a or newer, and Galaxy S20 or newer support eSIM. Device must be carrier-unlocked.
Data usage tips
Budget 400-500 MB per day for diving booking apps, beach maps, WhatsApp coordination with tour operators, and social media. The underwater sculpture park at Molinière Bay is accessed by boat — upload photos when back at the marina on 4G. Grand Anse Beach resort areas have consistent signal.
Download offline maps for the rainforest interior and Carriacou ferry routes. A 7-day plan covers a typical Grenada island holiday with buffer.
