eSIMsData does not offer a true unlimited‑data eSIM for Oceania. All plans that bear the “Unlimited” label in their name actually provide a fixed amount of high‑speed data each day, after which the speed is throttled to 1250 kbps for the “Essential” tier or 2000 kbps for the “Plus” tier. For travelers who need higher data volumes, eSIMsData offers fixed‑data plans such as the Oceania 100 GB 30 days plan, which delivers 100 GB of high‑speed data for a month, or the Oceania Unlimited Plus 30 days plan, which supplies 2 GB of high‑speed data per day for 30 days, totalling 60 GB. These fixed bundles can be more cost‑effective for those who consume significant data without the need for a truly unlimited data allowance.
