No, nextSIM does not provide a truly unlimited data eSIM for Antigua and Barbuda. Every plan that uses the word “Unlimited” in its name actually has a data cap of 1GB or 2GB per day and, after the cap is reached, the speed is reduced to 512 kbps or 2000 kbps.
Travelers who need more data without the speed drop can choose among fixed‑data plans such as the 50GB, 40GB, or 30GB Global 30‑day Premium plans, or the 20GB 30‑day plans for Antigua and Barbuda. These plans give a larger, flat data allowance and, for most users, are more cost‑effective when a steady level of data is required.
