eSIMCard does not provide a truly unlimited high‑speed data plan for New Zealand. Every plan that carries “Unlimited” in its name is capped at 1 GB of high‑speed data (or 1 GB per day for multi‑day subscriptions). Once the cap is reached, the speed is throttled to 500 kbps or 512 kbps, depending on the specific package.
Travelers who need more data can choose from several fixed‑data options. For example, eSIMCard offers a 100 GB plan that is valid for 180 days and remains unthrottled, as well as a 100 GB plan valid for 90 days and a 50 GB plan for 90 days. These fixed plans are often more cost‑effective for users who consume large amounts of data over an extended period.
