eSIM4Travel does not provide an unlimited data eSIM for Antigua and Barbuda. The provider offers fixed data plans that are capped at specific amounts; the largest listed plan supplies 10GB of data for a validity of 30 days at a price of $66.11 USD, while a 5GB/30 days plan costs $33.46 USD and a 3GB/30 days plan costs $20.40 USD. All of these plans come with tethering allowed and are unthrottled.
Choosing a fixed data plan can be more cost‑effective for most travelers unless the user is a very heavy data consumer who would benefit from a Pay‑as‑you‑go model. Examples of the available fixed plans are the 10GB/30 days plan and the 5GB/30 days plan, which provide larger data allowances compared to the 1GB daily or weekly options.
