How to choose the right plan
- Light use — maps, messaging and browsing — needs about 1 GB per day.
- Heavy use — social video, streaming or hotspotting a laptop — plan for 2-3 GB per day or pick the largest plan.
- Match the validity to your trip length, with a day or two of buffer for delays.
How activation works
- Buy the plan and receive your eSIM by email within minutes.
- Install it from your phone settings while still at home — no store visit, no plastic SIM.
- Land in Antigua and Barbuda, enable the eSIM line, and you are online before leaving the airport.
All Antigua and Barbuda eSIM plans
V.C. Bird (ANU) after a Carnival weekend is a queue, not a relaxing SIM counter. Install an eSIM before you fly and the Dockyard taxi, the villa WhatsApp, and the Barbuda hop are already on the phone.
Flow and Digicel shops in St. John's can add a local number later. For a week that splits English Harbour and a Barbuda night, prepaid data that works on both islands — when the towers do — is the piece you want before you leave home.
