Astaroam eSIM Data Plans for Australia

Astaroam does not provide a plan that delivers truly unlimited high‑speed data for Australia. The plans that carry the “Unlimited” name actually offer 3GB of high‑speed data per day and, once the daily quota is reached, the speed is throttled to 1000kbps.

Instead, Astaroam offers fixed‑data options for travelers in Australia. A 20GB plan valid for 30 days costs $10.90 USD and allows tethering, giving a straightforward way to cover most usage needs. These fixed‑data packages can be more cost‑effective for regular travelers, while heavy‑data users may still find the 20GB or 10GB plans sufficient.

Astaroam does not offer an eSIM for Australia that includes a phone number or SMS capability. Their Australian eSIMs are data‑only plans.

If you need voice or text functionality you can use VoIP services such as WhatsApp, Telegram or iMessage over the data connection, but the accessibility of those apps can vary in different regions. Travelers should confirm that the apps they rely on are available in Australia before purchasing the eSIM.

Astaroam lists 14 single‑country data plans and 16 multi‑country data plans that are available for use in Australia. The cost of each plan ranges from roughly $2.15 to $35.89 USD, with data allowances spanning from 1 GB up to 20 GB and validity periods between 3 and 30 days. Plans are divided into two main types: fixed data cap plans, in which a set amount of data is purchased for the duration of the validity, and daily data cap plans, where the data allowance is reset each day. This structure provides travelers who need consistent data usage as well as those who only require small amounts of data for short periods.
