mobineX does not offer a truly unlimited data eSIM for Australia. Every plan listed has a fixed data limit, such as 28 GB for 3 days, 42 GB for 5 days, 52 GB for 7 days, 65 GB for 10 days, 91 GB for 15 days, and 169 GB for 30 days; after reaching the cap, the speed is reduced (for the lower‑cap options the speed drops to 128 kbps after 1 GB or to 1024 kbps after 5 GB).
Travelers who need a larger data allowance can choose one of the fixed‑data plans, for example the 28 GB 3‑day or the 169 GB 30‑day options. These provide a cost‑effective way to access high‑speed data for a set period while still being subject to a clear data limit.
