4S eSIM eSIM Data Plans for Antigua and Barbuda

4S eSIM does not provide a truly unlimited data eSIM for Antigua and Barbuda. All plans listed for this destination have a specific data cap, and the term “Unlimited” in the plan name refers only to high‑speed data allocation until that cap is reached. After the limit is hit, the data speed is reduced to 1000kbps.

Travelers can instead choose from fixed‑data plans that offer large allowances. For example, the Global 50GB eSIM is available for 5, 7, 15, 30, or 90 days, and the Global 20GB eSIM is sold for 5 or 7 days. These options provide a sizable amount of data before throttling and can be more cost‑effective for users who need substantial data during their stay.

4S eSIM does not provide an Antigua and Barbuda eSIM plan that includes a local phone number or SMS capability. The provider offers only data‑only eSIMs for this destination. Travelers who wish to make calls or send messages may rely on VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, though access to these services can sometimes be restricted or blocked in Antigua and Barbuda, so it is advisable to confirm that the apps you need are available before purchasing a plan.
