Jetpac does not provide a truly unlimited data eSIM for Australia. All plans that include “Unlimited” in the name give a fixed 3 GB per day allowance, and after that limit the speed is throttled to 1024 kbps.
If a high‑data plan is preferable, Jetpac offers several fixed‑data options with larger caps that can be more cost‑effective for heavy users. For example, the 40 GB plans (Australia 40GB, 40 GB available for 30 days) and the 50 GB Global plan (available for 365 days) give a larger bandwidth budget and keep high‑speed data throughout the validity. These plans allow unlimited usage within the set data cap without the reduced speed that applies after the 3 GB/day limit of the “Unlimited” plans.
