ZenSim eSIM Data Plans for Australia

ZenSim does not currently provide any truly unlimited data eSIM plans for Australia. The packages that list “Unlimited” in their name, such as the Asia+ Unlimited STANDARD – 10 Days and – 30 Days, actually offer 3 GB of high‑speed data per day; once this daily limit is reached the connection speed is throttled. For travelers who need a larger fixed amount of data without the daily restriction, ZenSim offers 20 GB plans such as Oceania 20GB – 10 Days and Australia 20GB – 30 Days, which provide a single data block that can be used over the entire validity period before any speed reduction applies. Selecting a fixed data plan may be more economical unless a user requires very heavy, continuous data usage.

ZenSim does not provide an Australia eSIM that includes a local phone number or SMS capability. Travelers who use ZenSim can select a data‑only plan and then rely on VoIP services such as WhatsApp, Telegram, or iMessage to make calls and send messages over the data 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.
