Frequently Asked Questions
Is there coverage on Barbuda?
Barbuda has basic 4G in Codrington village. The beach areas, Frigate Bird Sanctuary, and much of the island's interior have no coverage. Download offline maps and book accommodation details before taking the ferry.
Does FLOW cover English Harbour and the marina area?
Yes — English Harbour and Falmouth Harbour have reliable FLOW 4G. These are the sailing hubs and connectivity is good for marina logistics, weather apps, and social media.
Does Uber operate in Antigua?
Uber does not operate in Antigua. Licensed taxis are metered — the government sets rates from the airport. Having data allows you to look up the official fare schedule and contact specific taxi drivers.
Is the Barbuda ferry reliable?
The ferry from St. John's to Barbuda (1.5 hours) operates several days per week but is subject to weather cancellations. Always check the schedule and confirm your reservation the day before travel.
What's the best way to navigate around Antigua?
Google Maps has good Antigua coverage. Car rental is the most practical way to explore — the island has over 150 beaches and many are down unmarked tracks. Data is essential for navigation.
Are there internet restrictions in Antigua?
No internet censorship operates in Antigua. All standard apps and services work without restriction.
What speeds can I expect in St. John's?
FLOW delivers 15–35 Mbps on 4G in St. John's and the main resort areas.
Does this eSIM cover other Caribbean islands nearby?
No — this plan covers Antigua and Barbuda only. A Caribbean regional plan would be needed for coverage across multiple islands.

eSIM Guide for Antigua & Barbuda
Your eSIM connects to major carriers in Antigua & Barbuda:
Available networks: 4G
Antigua and Barbuda is a dual-island Caribbean nation known for its 365 beaches and as a world-class sailing destination. FLOW provides 4G coverage across Antigua, the main island, which supports most travel needs — navigation to Barbuda by ferry, checking weather and wind forecasts for sailing, and booking activities through resort concierge apps. Antigua Sailing Week and the Classic Yacht Regatta draw serious sailors who rely on data for weather routing and VHF channel updates.
FLOW's 4G is solid across Antigua's main populated areas — St. John's, English Harbour, Falmouth Harbour, and Dickenson Bay. English Harbour is the hub of Antigua's sailing scene and has reliable connectivity for marina logistics. Barbuda, the sister island, has basic coverage in Codrington village but the island is largely rural — the famous Frigate Bird Sanctuary and pink sand beaches have no signal.
The ferry to Barbuda takes about 1.5 hours from St. John's. Schedule apps are useful but service is sometimes cancelled due to weather — check before heading to the terminal. Barbuda was largely destroyed by Hurricane Irma in 2017 and is still rebuilding; accommodation options are limited and reservations should be confirmed via WhatsApp.
Antigua's Shirley Heights viewpoint, Nelson's Dockyard (a UNESCO World Heritage site), and Devil's Bridge are must-see spots. Google Maps works well across the island. Uber does not operate — local taxis are metered and data helps with fare estimates and driver contact.
An eSIM is much simpler than buying a local FLOW SIM, particularly given the short visit durations that most Antigua travelers have.
