JamboSim eSIM Data Plans for Australia

JamboSim does not provide a truly unlimited data eSIM for Australia. The plans that carry “Unlimited” in their name actually allow 3 GB of high‑speed data each day; after that limit the speed is reduced to 1 Mbps. Because the high‑speed allowance is capped, the name is misleading if interpreted as unlimited access.

Travelers who need a larger, fixed data amount can choose one of JamboSim’s fixed data plans. For example, the eSIM Australia 20GB / 30 days plan costs $11.99 USD and permits 20 GB of high‑speed data for a month, while a similar 20GB / 30 days plan is available for Australia + 7 countries at $13.99 USD. These fixed plans can be more cost‑effective for those who consume more data than the daily 3 GB limit.

JamboSim provides eSIM plans for Australia that include a phone number and the ability to send SMS, though the number uses the dialing code +1 and only supports outbound voice and outbound SMS. Prices start at $11.99 USD for 1GB with 7 days of validity and go up to $105.99 USD for 20GB with 365 days of validity, covering a range of data caps from 1GB to 20GB and validity lengths from 7 days to 365 days. Users who need specific inbound voice or SMS capabilities should confirm the details directly with JamboSim.

JamboSim offers 12 single‑country plans and 28 multi‑country plans for Australia. Some plans feature a fixed data amount while others allow a daily data cap. Prices for the options fall between $1.99 and $105.99, with data caps ranging from 200 MB to 20 GB and validity periods spanning from 3 to 365 days.
