Astaroam eSIM Data Plans for Australia

Astaroam does not offer any plan with an unrestricted data allowance for Australia. Every plan that uses the word “Unlimited” in its name actually provides 3GB of high‑speed data each day; once this amount is reached the speed is throttled to 1000kbps.

If a higher data allotment is required, Astaroam’s fixed‑data plans are an option. For example, the 20GB plan for 30 days is available for $11.04 USD for Australia, and a 10GB plan for 30 days costs $9.33 USD. These plans give access to the full buyer‑chosen data amount within the validity period without any speed reduction.

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.
