NextSIM’s eSIM plans for Antigua and Barbuda that carry “Unlimited” in the name actually provide a limited data allowance. Each of those plans is capped at 1GB per day or 1GB total, after which the speed is reduced to 512kbps or 2000kbps. Therefore, nextSIM does not offer a truly unlimited data eSIM for Antigua and Barbuda.
Travelers who need higher data volumes can choose from nextSIM’s fixed‑data plans. For example, a 50GB plan is available for 30 days at $1,282.64 USD, a 40GB plan for $1,026.11 USD, a 30GB plan for $769.59 USD, and a 20GB plan for $73.25 USD. These plans provide large data allowances without the speed reduction that applies to the “Unlimited” named plans, making them more cost‑effective for users who consume more data.
