nextSIM does not provide a truly unlimited data eSIM for Oceania. The plans that carry the “Unlimited” label give a fixed data allowance—such as 1 GB per day or 2 GB per day—and once that limit is reached the connection speed drops to a reduced rate of 512 kbps or 2000 kbps. Therefore, the high‑speed data is not unlimited.
If you need a larger amount of high‑speed data, nextSIM offers fixed‑capacity options. For example, the eSIM 20 GB 30 days Oceania plan gives 20 GB of data for 30 days, and there are several higher‑capacity plans such as the 30 GB, 40 GB, and 50 GB 30‑day options that cover Australia, New Zealand, and other nearby markets. Choosing a fixed data plan can be more cost‑effective, especially for travelers who consume a lot of data.
