Network coverage in Antigua and Barbuda
All 6 HelloRoam Antigua and Barbuda plans sit on FLOW, which is why the coverage picture is one network rather than two: FLOW runs 4G across Antigua, English Harbour, Dickenson Bay, Jolly Beach and the resort strip included, and drops to 3G around Codrington on Barbuda. Digicel is the second operator on Antigua and is not sold through international eSIM providers. Remote northern Barbuda sits off-network.
Coverage analysis
FLOW 4G covers the entire main island of Antigua including St. John's, English Harbour, Dickenson Bay, Jolly Harbour, Jolly Beach, and Half Moon Bay. V.C.
Bird International Airport has 4G in both terminals. Barbuda receives 3G/4G near Codrington and the main beach landing zones. Remote northern beaches on Barbuda are off-network.
Sailing in Falmouth Harbour and English Harbour maintains 4G for weather apps and race tracking during Sailing Week.
Activation
Install the eSIM QR code before your flight to V.C. Bird International Airport. FLOW registers the line in the arrivals hall.
No SIM card purchase and no registration counter. Your device must be carrier-unlocked. iPhone XS or newer, Pixel 3a or newer, and Galaxy S20 or newer all support eSIM.
Data usage tips
Budget 400-600 MB per day for beach bar and restaurant lookups, Google Maps around the island, and daily photo uploads. Sailing Week visitors pulling race results, weather GRIB files and marine apps use 800 MB to 1 GB per day, which points at the 10 GB plan at $68.52. Download offline maps before the Barbuda ferry: signal near the frigate bird sanctuary thins out.
Video calls from English Harbour use 400-600 MB per hour.

Antigua and Barbuda prices reflect small-island infrastructure costs. The 1 GB plan costs $10.13 over 7 days. The 3 GB plan costs $23.94 and the 5 GB plan $37.55, which is $7.51 per GB.
