ZenSim eSIM Data Plans for Australia

ZenSim does not offer a true unlimited high‑speed data eSIM for Australia. The plans that carry “Unlimited” in the name, such as the Asia+ Unlimited STANDARD – 10 days and – 30 days, actually provide a cap of 3 GB of data per day, after which the speed would be reduced. For travelers who need more data, ZenSim provides fixed‑data options that are more cost‑effective. A 20 GB plan is available for 10 days at $27.00 USD and another 20 GB plan for 30 days at $30.00 USD, both of which give a set amount of high‑speed data that can be used throughout the validity period.

ZenSim does not provide an Australia eSIM that includes a phone number or SMS capability. All of the available plans for Australia are data‑only, meaning users cannot receive or send voice calls and text messages directly via a local SIM number. However, travelers can still use data‑based messaging and calling apps such as WhatsApp, Telegram, and iMessage over the eSIM connection.

ZenSim offers 6 single‑country plans and 14 multi‑country plans that include coverage in Australia. The plans are grouped into two main types: fixed data‑cap plans provide a set amount of data for the entire validity period, whereas daily data‑cap plans spread the data allowance across each day of the plan. Overall, the available offers range in price from about $13 to $70 and in data allowance from 3 GB to 20 GB, with validity windows between 10 and 30 days.
