Grenada network coverage on FLOW

HelloRoam runs its Grenada plans on FLOW, part of Liberty Latin America, which is why the recommendation here follows the southwest tourist corridor: FLOW is the carrier holding 4G from St George's through Grand Anse to Lance aux Épines. Digicel operates on the island but has lower penetration for eSIM-compatible plans. FLOW serves the wider Eastern Caribbean region with consistent infrastructure across Grenada's three islands, and it is the single network listed for all 6 Grenada plans on file.

通信範囲の分析

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.

開通方法

Install your eSIM QR code before flying into Maurice Bishop International Airport (GND). FLOW registers the profile on arrival, with no SIM counter to queue at. Grenada is English-speaking, which keeps support straightforward for most international visitors. iPhone XS or newer, Pixel 3a or newer, and Galaxy S20 or newer support eSIM.

Your device must be carrier-unlocked.

データ通信の活用のコツ

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.

GrenadaのeSIMプラン料金

Grenada eSIM plans start at $10.98 for 1 GB over 7 days on FLOW. The 3 GB plan costs $26.10 and the 5 GB plan $40.80, both over 30 days. The 10 GB plan at $74.66 is the value step at $7.47/GB.

A 20 GB plan runs $164.45 for long stays. A 2 GB per day plan costs $18.00, with a fair-use speed reduction once the daily allowance is spent. Caribbean eSIM pricing reflects the region's higher per-capita data costs.

Verdict: HelloRoam prices Grenada from $10.98 for 1 GB on FLOW 4G, on the only network the territory offers an eSIM buyer.
