MobileSIM eSIM Data Plans for Australia

MobileSIM does not provide a truly unlimited data eSIM for Australia. All plans that carry “Unlimited” in the name actually have a capped data allowance of 3 GB per day; once the 3 GB limit is reached the speed is reduced to 1000 kbps.

Plan options that use a fixed data capacity are available instead. For example, a 20 GB plan for 30 days costs $30.00 USD, and a 10 GB plan for 30 days is $18.00 USD. These fixed‑data plans give a higher overall data allowance and can be more cost‑effective for travelers who need more than the 3 GB/day limit.

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 lists 12 single‑country plans and 20 multi‑country plans for Australia. The available plans range from $2.30 to $165.00 in price and provide between 200 MB and 60 GB of data, with validity periods spanning 3 to 125 days. MobileSIM offers both daily‑cap and fixed‑cap data models; daily‑cap plans reset their data allowance each day, whereas fixed‑cap plans provide a total data quota for the entire validity period, and some plans include reduced speed once the cap is reached.
