JamboSim eSIM Data Plans for Australia

JamboSim does not provide a truly unlimited high‑speed data eSIM for Australia. The plans labeled “Unlimited” give 3GB per day and after that threshold the speed is reduced to 1000 kbps; this is a capped amount of high‑speed data rather than an unlimited allowance. Travelers who need more high‑speed data can choose one of JamboSim’s fixed data plans, such as the 20 GB 30‑day plan that offers a larger high‑speed data allowance before any throttling occurs.

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 that cover Australia and 43 multi‑country plans that include the country. The plans are split between fixed‑data‐cap options—where a set amount of data is available for the validity period—and daily‑data‑cap options, which limit usage to a maximum amount per day. Pricing ranges from $1.99 to $125.99, while data caps vary from 200 MB up to 20 GB.
