MobileSIM eSIM Data Plans for Australia

MobileSIM does not sell a truly unlimited high‑speed data package for Australia. The plans with “Unlimited” in the name actually provide only 3GB/day of full‑speed data; once that limit is reached the speed drops to 1000kbps. These plans are therefore capped rather than unlimited.

If you need more unrestricted data, MobileSIM offers fixed‑data options that may be more cost‑effective. For instance, an Australia 10GB plan for 30 days costs $18 USD, and an Australia 20GB plan for 30 days costs $30 USD. These plans offer a larger total data allowance without the daily cap that the “Unlimited” plans impose.

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.
