ZenSim does not provide a truly unlimited data eSIM for Anguilla.
Although some plans are labeled as “Unlimited” in their name, they contain a hard cap of 3 GB per day and a reduced speed of 1000 kbps after that limit is reached, so the data is not unlimited.
Travelers can choose fixed data plans instead. For example, ZenSim offers Anguilla 20 GB for 15 days at $59.40 USD and for 30 days at $67.50 USD, as well as an Anguilla 10 GB plan for 15 days at $37.80 USD. These options provide a larger data allowance on a set validity period and may be more cost‑effective for most travelers.
