TailSim eSIM Data Plans for Australia

TailSim does not provide a truly unlimited data eSIM for Australia. The plans under the “Unlimited” name give 2GB per day and, once that amount is reached, traffic is throttled to 1000 kbps, so the data is not unlimited.

Travelers who need more data may choose one of TailSim’s fixed‑data plans, such as the 50 GB bundle for 30 days or the 20 GB plan for 30 days. These options offer large data allowances without the daily limits and can be more cost‑effective for most users.

TailSim does not provide an Australia eSIM that includes a phone number or SMS capability. The provider offers only data‑only plans for travelers in Australia. Users who need voice or messaging can rely on VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should verify that these services are accessible in Australia before purchasing, as some destinations may block or restrict certain apps.

TailSim offers 14 single‑country data plans for Australia, with no multi‑country options. The plans range in price from $3.99 to $82.50 and provide data amounts between 1 GB and 50 GB over 3 to 30 days. Among the offerings, eight plans have a daily data cap, giving you a fixed amount of data each day, while six plans feature a fixed data cap that is available for the entire validity period. All plans allow tethering, and some include a reduced speed option of 1000 kbps.
