Stellar eSim does not offer a true unlimited‑data eSIM for Oceania. All of its plans for Australia and New Zealand contain a fixed data cap ranging from 1 GB to 3 GB, or larger bundled plans such as 20 GB for 20 or 30 days, 50 GB for 180 days, and 50 GB for 365 days. These fixed data plans are generally more cost‑effective for most travelers, while a Pay‑as‑you‑go option is also available for those who prefer to purchase credit that can be topped up as needed.
