eSIMatrix does not provide an unlimited data eSIM for Anguilla. All of its plans for the island carry a fixed data allowance of 20GB, with validity ranging from 5 days to 30 days.
The provider offers several 20GB options, such as Anguilla 20 GB – 5 days for $84.50 USD, Anguilla 20 GB – 10 days for $94.00 USD, Anguilla 20 GB – 15 days for $99.00 USD, and Anguilla 20 GB – 30 days for $103.50 USD. These plans are examples of the fixed‑data offerings available and may be more cost‑effective for most travelers unless the user requires an extremely high data consumption that would otherwise warrant an unlimited plan.
