Select a plan

Looking for an Australia total-data eSIM, a Sydney eSIM, or one pack for the whole trip? Optus total data is Australia roaming with a Singapore IP and one shared allowance for the validity period. It suits multi-day trips when you want to manage total usage.
Why choose Australia total data?
•
The simple way: Scan the QR code and go—no physical SIM swap. Most phones fill in APN e-ideas automatically. Just choose the days and the total allowance.
•
One shared allowance: Choose 1GB, 3GB, 5GB, 10GB, 20GB, 30GB, or 50GB. After the high-speed data, service continues at about . Messaging still barely works; video and hotspot use slow down.
•
Optus coverage: 4G/5G is steadier in Sydney, Melbourne, Brisbane, the Gold Coast, and Perth; it drops inland and on remote roads.
•
Exit IP: Traffic goes out through a Singapore IP, so ChatGPT, TikTok, and Gemini generally work.
•
Hotspot and common apps: Hotspot, ChatGPT, TikTok, and Gemini are supported. Sharing is smoother within the high-speed allowance.
•
Days: Choose 3, 5, 7, 10, 15, 20, 25, or 30 days, as shown on the page.
•
Who should choose this / switch: Choose this to share one pack across several days. For an allowance that resets daily, switch to Australia daily. To stay online all day without counting data, switch to Australia unlimited. For study or business of 20 days or more, see Australia long stay.
•
Activation: You can install it on Wi‑Fi in Taiwan, then turn this line and mobile data on after arriving in Australia. The validity period starts then.

Real-world experience

Within the high-speed allowance, urban 4G/5G speed tests in Sydney, Melbourne, and Brisbane commonly reach tens of Mbps. Afterward, about is barely enough for messaging and light pages; video and hotspot use become difficult. For reference only.
