Astaroam eSIM Data Plans for Australia

Astaroam does not provide a truly unlimited data eSIM for Australia. The plans whose titles include “Unlimited” actually allot a fixed amount of high‑speed data—3GB per day for the duration of the plan—and after that amount is reached the speed is throttled to 1000 kbps.

Instead, Astaroam offers fixed data plans that may be more cost‑effective for most travelers. For example, the “Australia 20GB 30Days” plan provides 20 GB of high‑speed data usable for 30 days, and the “10 GB - 30 days” plan gives 10 GB for the same period. These plans allow tethering and use the 5G network across Australia.

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 offers 16 single‑country data plans that cover Australia exclusively, and 21 multi‑country plans that include Australia as part of a broader region. The single‑country options range in price from about US$1.99 to US$34.88, with data caps that span 1 GB to 20 GB and validity periods of 3 to 30 days. For users preferring a broader coverage, the multi‑country plans fall within the same price and data ranges, providing a daily data cap option or a fixed data amount depending on the specific plan chosen. The variety of offerings allows travellers to select a plan that matches both budget and data‑usage needs.
