MobileSIM eSIM Data Plans for Australia

MobileSIM does not provide a truly unlimited data eSIM for Australia. The plans that carry “Unlimited” in their name actually give 3 GB per day of high‑speed data and, once that daily limit is reached, the speed is throttled to 1000 kbps.

Travelers who need more data can choose MobileSIM’s fixed data plans. For example, the Australia 20 GB for 30 days plan costs $30 USD, the Australia 10 GB for 30 days plan costs $18 USD, and the Global 60 GB for 125 days plan costs $165 USD. These fixed data plans offer larger data allowances and can be more cost‑effective unless the user is an extremely heavy data consumer.

MobileSIM does not provide eSIM plans for Australia that include a phone number or SMS capability. Travelers who need a local line in Australia will only find data‑only eSIM options from MobileSIM, which use a VoIP or messaging app for communication.

If calls and text messages are required, users can rely on internet‑based services such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict access to these apps, so it is advisable to confirm that the messaging or calling apps you rely on are available in Australia before purchasing an eSIM.

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.
