AirDataLink does not provide an unlimited data eSIM plan for Oceania. All of its available offerings for Australia and New Zealand have a defined data cap, the largest of which is 50 GB.
AirDataLink’s fixed data plans give several high‑allowance options. For example, the 50 GB eSIM lasts 15 days or 30 days, and there are also 30 GB plans with the same validity options. These fixed plans expire after their stated period and can be more cost‑effective for average travelers, but they are not unlimited and will require a new purchase if more data is needed.
