FLOW coverage across the Grenadines
FLOW is the primary 4G carrier in Saint Vincent and the Grenadines, operating across the main island and all major Grenadine cays. Coverage extends from Kingstown on Saint Vincent south through Bequia, Mustique, Canouan, Mayreau, and the Tobago Cays. FLOW provides the only reliable eSIM-compatible 4G service throughout the archipelago.
Remote Grenadine cays and outer anchorages have reduced signal.
Coverage analysis
FLOW 4G covers Kingstown city and port, Argyle International Airport, and the Windward and Leeward highway systems on Saint Vincent. Bequia's Admiralty Bay and Port Elizabeth have solid 4G. Mustique has reliable coverage in Britannia Bay and the airport area.
Canouan has coverage near the marina and Raffles resort. The Tobago Cays (uninhabited marine park) and remote anchorages have intermittent 2G-4G coverage. Young Island and Palm Island maintain FLOW signal.
Activation
Install your eSIM QR code before flying into Argyle International Airport (SVD) on Saint Vincent. FLOW activates automatically on landing. Enable data roaming in your phone settings.
No counter registration or SIM shop required. iPhone XS or newer, Pixel 3a or newer, and Galaxy S20 or newer support eSIM. Carrier-unlock your device before departure.
Data usage tips
Kingstown visitors use 400-600 MB per day for navigation, restaurant apps, and social media. Sailors on Grenadines charter routes need connectivity for marine weather apps (PredictWind uses 100-200 MB per day), marina booking via WhatsApp, and route planning. The unlimited plan suits yacht charters where usage varies daily.
Download offline charts as backup for the Tobago Cays and remote anchorages where signal is intermittent.
