eSIMsData does not provide a true unlimited data eSIM for Australia. The plans that include “Unlimited” in their names only give a fixed high‑speed allowance each day—1 GB or 2 GB per day—after which the speed is reduced to 1250 kbps or 2000 kbps, respectively. Because the data cap is a hard limit, the plans are considered fixed data plans, not unlimited.
Travelers who want a larger data allowance can choose fixed plans such as the Australia 100GB 30 days plan for $51.69 USD or the Australia Unlimited Plus 30 Days plan that provides 2 GB of high‑speed data per day for $93.60 USD. These plans offer larger total data and can be more cost effective for high‑usage travelers.
