Stellar eSim does not offer a true unlimited‑data eSIM for Australia. All of its plans that carry the “Unlimited” name provide a capped amount of high‑speed data, ranging from 2GB to 3GB for the specified validity period. After that data is used, the plan’s speed would be reduced, as per the provider’s own description.
Travelers can choose from fixed data plans instead. For example, the 100GB plan for 60 days and the 50GB plans for periods ranging from 15 to 180 days provide much larger data allowances. These fixed plans allow users to pay for a definite data amount without a hard data cap, making them a more cost‑effective choice for those who need more data during their stay in Australia.
