ZenSim does not provide a truly unlimited data eSIM for New Zealand. Their plans that carry the word “Unlimited” actually allow 3 GB of high‑speed data each day for the plan’s validity period, after which no additional data is delivered at the bandwidth specified for the plan.
If a larger data allowance is needed, ZenSim offers flat‑rate plans such as the 20 GB options valid for 10 or 30 days, which deliver the full 20 GB of high‑speed data during the validity window. For travelers who use a moderate amount of data, a fixed‑data plan can be more cost‑effective than the 3 GB/day “Unlimited” packages.
