eSIMsData does not provide a true unlimited‑data eSIM for New Zealand.
The plans that carry the word “Unlimited” in the name actually offer a daily high‑speed allowance (1 GB or 2 GB per day) and switch to a reduced speed once that limit is reached.
Travelers who need a larger amount of data before any throttling can choose from eSIMsData’s fixed data plans, for example the 100 GB 30 day plan available only in New Zealand, or similar long‑term fixed plans that provide a set data allowance for the duration of the validity period.
