ZenSim does not currently provide any truly unlimited data eSIM plans for Australia. The packages that list โUnlimitedโ in their name, such as the Asia+ Unlimited STANDARD โ 10 Days and โ 30 Days, actually offer 3โฏGB of highโspeed data per day; once this daily limit is reached the connection speed is throttled. For travelers who need a larger fixed amount of data without the daily restriction, ZenSim offers 20โฏGB plans such as Oceaniaโฏ20GB โ 10 Days and Australiaโฏ20GB โ 30 Days, which provide a single data block that can be used over the entire validity period before any speed reduction applies. Selecting a fixed data plan may be more economical unless a user requires very heavy, continuous data usage.
