RoameSIM eSIM Data Plans for Australia

RoameSIM does not provide a truly unlimited high‑speed data eSIM for Australia. All plans labelled “Unlimited” give a fixed allowance of 3 GB per day; after that threshold the connection speed is reduced to 1000 kbps, so the data itself is not unlimited.

RoameSIM offers fixed data plans that can be used for longer periods in Australia, such as 20 GB for 30 days (US$42) or 60 GB for 125 days (US$208.60). These fixed‑data options may be more cost‑effective than the daily‑limit plans for travelers who need a predictable amount of data.

RoameSIM provides Australia eSIM plans that include a phone number and SMS functionality. The available plans range in data capacity from 1GB to 20GB, validity from 7 days up to 365 days, and prices between $21.00 USD and $124.60 USD. Each plan assigns a phone number with the dialing code +1, meaning the number is not locally Australian but is usable abroad. Calls can be received and made, and SMS messages can be both received and sent using these SIMs. Users should verify specific details directly with RoameSIM in case they need particular telephony features.

RoameSIM provides 12 single‑country plans that include Australia and 29 multi‑country plans that also cover Australia. The available plans span a price range of approximately $2.40 to $208.60 and offer data caps from 200 MB up to 60 GB. Among the plans, some are fixed‑data packages—where a set amount of data is allocated for the entire validity period—while others employ daily data caps, allowing users to consume up to a specified amount each day until the plan expires.
