MobineX does not sell a truly unlimited high‑speed data eSIM for Australia. The plans that carry the “Unlimited” name all have a fixed data allowance, after which the network speed drops—examples include the Unlimited Gold plan with 5GB at 1024kbps after the limit and the Unlimited Standard plan with 1GB at 128kbps after the limit.
Travelers who need more generous data can choose from fixed‑data options. For instance, a 169GB plan valid for 30 days costs $61.50 USD, and a 52GB plan for 7 days is available for $25.50 USD. A 100GB plan for 60 days is also offered for $120.00 USD. These fixed plans may provide better value for those who consume large amounts of data during their stay in Australia.
