nextSIM does not provide a truly unlimited data eSIM for travel in New Zealand. The plans that carry “Unlimited” in their names all have listed data caps, such as 1 GB for the eSIM New Zealand Unlimited 1Days Standard plan or 2 GB for the eSIM New Zealand Unlimited Plus 1Days Standard plan. After the cap is reached, the speed is throttled to a reduced rate (512 kbps or 2000 kbps respectively).
If a higher data allowance is needed, nextSIM offers fixed‑data alternatives, for example the eSIM Pro New Zealand 200GB 90Days Mobile Data + SMS Number plan, which gives 200 GB for 90 days, or the various eSIM New Zealand Unlimited 3Days or 7Days Standard plans that provide 1 GB per day. These fixed plans can be more cost‑effective for users who are heavy data consumers.
