Good to know
Coverage is strong across Antigua's resort coast and St. John's, but thins on Barbuda — download offline maps before the ferry over to the frigate bird sanctuary and pink-sand beaches.
Prepaid, honestly.

Fixed-data bundles have no daily cap — the gigabytes are yours until they're used or the plan ends. Every plan is prepaid: the checkout total is the whole bill, and we never add overage charges.

Hotspot support varies by plan and destination — where it's available for your plan in Antigua and Barbuda, it's shown in the plan details before you pay.

The Antigua and Barbuda eSIM guide.

Antigua and Barbuda packs 365 beaches, a UNESCO-listed Georgian dockyard and two very different islands into one Caribbean holiday. Between St. John's markets, catamaran day trips and Shirley Heights sundowners, an eSIM keeps you posted — booking excursions, sharing beach photos, mapping the drive and video-calling home without hunting for resort Wi-Fi.

How it works on the day

Install your eSIM before you fly and it connects to Flow or Digicel the moment you land at V.C. Bird International. Scan the QR at home over Wi-Fi, keep your usual number for calls and messages, and skip the arrivals-hall SIM queue entirely.

Choosing your days

Most visitors stay five to ten days across a beach week or a sailing charter. Pick a plan that matches — a lighter data bundle for maps and messaging, or a larger one if you're streaming and posting daily. Day-rate plans suit a single cruise stop.

The short version.

A travel eSIM is data only. It sits next to your home SIM, so your number, texts and WhatsApp carry on as normal. Pick a bundle of GB sized to the trip. Install it on Wi-Fi before you fly — the days only start once it first connects in Antigua and Barbuda, and it finds a partner network on its own.
