MobileSIM eSIM Data Plans for Australia

MobileSIM does not provide a truly unlimited high‑speed data plan for Australia; every plan listed has a fixed data cap and reduces speed to 1000kbps once the limit is reached. For example, the “Australia Unlimited data for 7 days” plan supplies 3 GB per day and throttles speeds after that amount.

If more data is needed without the speed reduction, MobileSIM offers fixed‑data options, such as the 20 GB for 30 days plan at $30.00 USD and the 10 GB for 30 days plan at $18.00 USD. These plans give a larger block of high‑speed data and can be more economical for travelers who do not require an absolute unlimited data allowance.

MobileSIM does not offer an eSIM plan for Australia that includes a phone number or SMS capability. The provider only supplies data‑only eSIM plans, so travelers must use data connections for messaging and calling through VoIP applications such as WhatsApp, Telegram, or iMessage.

MobileSIM provides 12 single‑country data plans and 15 multi‑country data plans for travelers visiting Australia. The plans cover a price range from $4.50 to $66.50 USD and offer data caps between 1 GB and 20 GB. Among the offerings, some plans feature a daily data cap that resets each day, while others use a fixed data cap that remains usable until the plan expires. This selection allows users to choose either daily flexibility or total data for the entire validity period.
