No. eSIMCard does not offer any plan with a true unlimited data cap for Australia. All of the Australian plans listed by eSIMCard have a finite data allowance, such as 100GB for 30 days or the various fixed‑data “Unlimited” names that actually provide a capped amount of high‑speed data before speed throttling occurs.
If a traveler needs a large amount of data, the fixed data plans are the alternatives to consider. For example, eSIMCard’s 100GB eSIM Data for 30 days for Australia is available for $87.02 USD, and the Orange 100GB bundle – which also includes talk time and text – is offered for $56.47 USD. These fixed data plans give a clear data ceiling but can be more cost‑effective for most users compared to repeatedly topping up a pay‑as‑you‑go balance.
