eSIM Cards does not provide a truly unlimited data eSIM for New Zealand. The only North‑American‑style “Unlimited” plans that appear in its catalogue for this destination come with a fixed data quota of 1,000GB, after which the speed is throttled. For example, the New Zealand Unlimited data with calls Travel eSIM for 15 days costs $32.05 USD and the 30‑day variant costs $41.39 USD; both offer tethering and may reduce speed once the 1,000GB limit has been reached.
If a user needs very large amounts of high‑speed data without a strict cap, choosing a fixed‑data plan may be more cost‑effective. Plans such as a 1,000GB package for 15 or 30 days provide substantial capacity, and after the quota is used the connection is still available at a reduced speed instead of being cut off entirely. This allows travelers to keep their data available for essential usage while still incurring a low cost compared to unlimited plans that lock in perpetual speed.
