Airalo does not offer a truly unlimited data eSIM plan for Antigua and Barbuda. The plans that carry the word “Unlimited” in their name provide a capped amount of high‑speed data—3GB per day for a set validity period—and after that amount the speed is throttled to 1000kbps.
If a traveler wants a larger high‑speed data allowance, Airalo provides fixed data plans such as the 20GB Discover–20GB plan, valid for 365 days, or the 10GB Island Hopper plans, which range from 7 to 30 days of validity. These fixed plans offer a clear data limit but no throttle penalty once the data is exhausted, making them a more cost‑effective choice for heavy‑data users who need a predictable amount of high‑speed connectivity in Antigua and Barbuda.
