JamboSim eSIM Data Plans for Australia

JamboSim does not provide a truly unlimited data eSIM for Australia. Plans that carry the word “Unlimited” in their name give 3 GB of high‑speed data each day. Once that daily allotment is reached, the speed is reduced to 1000 kbps, so the data is not unlimited in the sense of continuous, unrestricted high‑speed connectivity.

Travelers can instead choose from fixed‑data options. For example, the eSIM Australia 20GB / 30 days plan offers 20 GB of high‑speed data for a month, and a similar 20 GB / 30 days plan is available for the broader Oceania coverage. These fixed plans provide a known data allowance and can be more cost‑effective for most users unless very heavy data consumption is anticipated.

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 data plans for Australia. The company does not list any separate multi‑country plans that are specifically for Australia; all cross‑border options are included in the broader multi‑country package. Prices for the Australian plans range from $1.99 to $94.99, data caps span from 200 MB up to 20 GB, and validity periods can be as short as 3 days or as long as 365 days.
