Simsima eSIM Data Plans for Australia

Simsima does not provide genuine unlimited‑data eSIM plans for Australia. The plans that carry the label “Unlimited” actually allow 3 GB per day and then throttle traffic to 1000 kbps; the data amount is capped, so the plan is not unlimited. Travelers who want more data can choose from Simsima’s fixed data plans, such as the Australia 50GB 30Days plan or the 20 GB 30‑day or 20 GB 365‑day bundles, which offer larger data allowances over their validity periods.

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.

Simsima provides 12 single‑country data plans that cover Australia alongside 14 multi‑country options that include the country in their coverage. The plans differ mainly in how data is allocated: daily data cap plans reset each day, limiting usage for any single day, whereas fixed data cap plans allow the entire data allotment to be used over the plan’s validity period, which ranges from 5 to 365 days. Across all offerings the price spectrum extends from about $1.50 to $84.83, while the data caps vary between 100 MB and 50 GB, giving travelers a wide range of budget and usage options for their stay in Australia.
