MTX Connect does not provide an unlimited data eSIM plan for New Zealand. The service offers fixed‑data plans that have a hard data cap and a specified validity period, such as a 10 GB plan valid for 30 days or a 4 GB plan valid for 14 days. These plans give travelers a clear maximum amount of data that must be used before the plan expires, and any additional data can be added later through Pay‑as‑you‑go top‑ups, but the standard packages themselves are capped, not unlimited.
