FLOW across both islands
Your eSIM connects to FLOW on 4G, covering Antigua and Barbuda on one plan. St John's, English Harbour, Falmouth, Jolly Harbour and Dickenson Bay are all well covered, as is most of Antigua's road network.
Barbuda, an hour and a half away by ferry, is far less developed and coverage there is concentrated around Codrington. The famous pink sand beach on the west side is patchy.
Sailing, and where the signal stops
Antigua is a serious sailing destination — English Harbour and Falmouth fill with yachts, and Sailing Week in spring brings the fleet in. Coverage around the harbours and the leeward coast is good.
Once you're properly offshore, or crossing to Barbuda, expect gaps. The ferry drops signal mid-crossing. If you're chartering, sort your provisioning and mooring arrangements from shore.
How much data
1 GB at £8.99 covers a week for most resort-based visitors, with hotel Wi-Fi handling the rest. If you're sailing or splitting time with Barbuda, 3 GB gives more room — though you'll be out of coverage for parts of it anyway.
Good to know
Questions, answered
Does the plan cover Barbuda as well?+
Yes, both islands are on the same plan. Barbuda is far less developed though — coverage concentrates around Codrington and is patchy at the pink sand beach.
Will I have signal sailing around the coast?+
Near shore and around English Harbour and Falmouth, yes. Properly offshore or on the Barbuda crossing, expect to lose it. Arrange moorings and provisioning from land.
How do I install it?+
After checkout we email your eSIM and a QR code. Scan it in your phone's settings, switch the line on, and you're ready — do it before you fly and it activates when you land.
Will it work on my phone?+
Most phones from the last few years support eSIM (iPhone XS and newer, recent Samsung/Pixel). Check your phone in Settings, or use our compatibility checker.
When does my plan start?+
Validity counts from first connection in the destination, not from purchase — so you can buy and install early without wasting days.
Can I keep using my normal number?+
Yes. The eSIM is data-only and runs alongside your usual SIM, so calls and texts on your main number still work.
