FLOW coverage across the Grenadines
Thirty-plus islands and one network is the whole story here, which is why the carrier decides the trip: HelloRoam runs its Saint Vincent and the Grenadines eSIM on FLOW, the only operator with 4G across the archipelago. FLOW reaches Kingstown and the Argyle airport corridor on Saint Vincent, then runs south through Bequia, Mustique, Canouan, Mayreau and the Tobago Cays marine park. Digicel operates in the region as well but is not a partner network for the visitor plans reviewed here.
Remote cays and outer anchorages carry reduced signal on every network.
通信範囲の分析
FLOW 4G covers Kingstown city and port, Argyle International Airport, and both the Windward and Leeward highway systems on Saint Vincent. Bequia holds solid 4G at Admiralty Bay and Port Elizabeth. Mustique carries reliable coverage at Britannia Bay and around the airstrip.
Canouan holds signal near the marina and the Raffles resort. The Tobago Cays, an uninhabited marine park, run intermittent 2G to 4G in the anchorage. Young Island and Palm Island both keep FLOW service.
The volcanic interior around La Soufriere thins out sharply above the coastal road, and the northern Windward coast beyond Georgetown drops in places.
開通方法
Install the eSIM QR code before you fly into Argyle International Airport (SVD) on Saint Vincent. FLOW registers the profile on arrival with no counter visit and no paperwork. Switch on data roaming in your phone settings. iPhone XS or newer, Pixel 3a or newer, and Galaxy S20 or newer all support eSIM.
Carrier-unlock your device before departure, because a locked handset will not attach to FLOW at any price. Kingstown has no airport SIM counter worth queueing for, so the SIM decision is made before you fly.
データ通信の活用のコツ
Kingstown visitors use 400 to 600 MB a day for navigation, restaurant apps and social media. Charter crews on the Grenadines route need marine weather, and PredictWind runs 100 to 200 MB a day on its own. Marina booking over WhatsApp and route planning add another 100 MB.
At $9.11/GB the 1 GB plan at $13.50 covers a short charter week when the boat has its own Wi-Fi. Download offline charts as backup for the Tobago Cays and the outer anchorages.
Saint Vincent and the GrenadinesのeSIMプラン料金
Saint Vincent and the Grenadines eSIM data reflects the cost of covering 30-plus islands. The 1 GB plan costs $13.50 for 7 days, 3 GB costs $31.80, 5 GB costs $49.50, 10 GB costs $91.13, and 20 GB costs $200.65. A 1-day plan costs $20.98 and carries a 2 GB daily allowance with a fair-use speed reduction past it.
Across all 6 plans the rate bottoms out at $9.11/GB, which is far above the $2.20/GB catalogue median.
