MobiMatter does not provide an unlimited‑data eSIM for Oceania. All of its plans for Australia, Fiji, New Zealand and other Oceanic countries are fixed data bundles. For example, the “Best World 50 GB 180 Days” plan gives 50 GB of high‑speed data that can be used for 180 days, and the “APAC 34 GB Yearly” plan offers 34 GB for 365 days. These plans are priced as one‑time purchases, and the data allowance is a hard cap that must be exhausted within the validity period. Choosing a fixed data plan can be more cost‑effective unless a traveler is an extremely heavy data user who would otherwise spend more on pay‑as‑you‑go credits.
