Simsima for Australia FAQ
Does Simsima offer unlimited data eSIM for Australia?
Simsima does not provide a truly unlimited high‑speed data eSIM for Australia. All plans that carry the word “Unlimited” in their name give 3 GB per day and reduce speed to 1000 kbps once the daily allowance is reached, so they are not unlimited in the sense of offering high‑speed data without limits.
Travelers looking for large data amounts can choose fixed‑data plans instead. For example, a 50 GB 30 day plan costs $31.54 USD, and a 20 GB 30 day plan is available for $18.52 USD. These plans offer high‑speed 5G data for the entire validity period and may be more cost‑effective for heavy users.
Does Simsima offer Australia eSIM with phone number and SMS?
Simsima does not offer eSIM plans in Australia that include a local phone number or SMS capability. The provider offers only data‑only eSIMs for the destination, so travelers will not receive a traditional Australian phone number with the plan.
If a traveler needs to make calls or send messages, VoIP applications such as WhatsApp, Telegram, or iMessage can be used over the data connection. Because some destinations may block or limit access to certain apps or VoIP services, it is advisable to verify that the apps required are available in Australia before purchasing a data‑only plan from Simsima.
How many data plans does Simsima offer for Australia?
Simsima lists 12 single‑country plans for Australia and 16 multi‑country plans that include Australia. The available plans span a price range from about $0.40 to $61.74 and offer data caps between 100 MB and 50 GB over validity periods of 5 to 180 days. Some plans provide a fixed data allowance, which delivers a set amount of data for the entire validity period, while others operate on a daily data cap, limiting how much data can be used each day.
