eSimfly eSIM Data Plans for Antigua and Barbuda

eSimfly does not provide a true unlimited data eSIM for Antigua and Barbuda. All of its current plans list a specific data allowance, such as 20GB for 30 or 365 days, or 3GB per day with reduced speed after the daily limit is reached. The plan named “Caribbean Islands Unlimited 7 Days” is limited to 3GB per day; once that cap is met, the speed drops to 1024 kbps, so it is not an unlimited high‑speed offering.

For travelers who need a larger data allowance without the restrictions of a daily cap, eSimfly’s fixed‑data plans—like the 20GB 30‑day or 365‑day options—may be more economical. These plans give a clear, predictable amount of high‑speed data, and can be cost‑effective unless you are an extremely heavy data consumer.

eSimfly does not offer eSIM plans with a local phone number or SMS capability for Antigua and Barbuda. Only data‑only eSIMs are available. Travelers can use internet‑based messaging and calling apps such as WhatsApp, Telegram or iMessage over the data connection to make calls and send messages.

eSimfly lists 9 single‑country data plans and 27 multi‑country plans that cover Antigua and Barbuda, for a total of 36 options. The plans range in price from about $4.38 to $100.19, with data caps between 1 GB and 25 GB. Among the offerings, one daily‑data‑cap plan limits usage each day, while the majority, 35 in total, provide a fixed data amount.
