simpleSIM does not provide any unlimited data eSIM plan for Antigua and Barbuda. Instead, the provider offers fixed data plans with a clear data cap. For example, the eSIM Antigua and Barbuda 20GB plan gives 20GB of data for 30 days at $67.24 USD, and the eSIM Antigua and Barbuda 10GB plan offers 10GB of data for 30 days at $56.03 USD. There is also a wider‑coverage option, the eSIM Caribbean 10GB plan, which includes Antigua and Barbuda along with 23 other Caribbean countries. Choosing a fixed data plan can be more cost‑effective, especially for most travelers, unless the user is an extremely heavy data consumer.
