Select a plan

Looking for an Australia daily eSIM, a Sydney eSIM, or an easy daily cap? Optus daily is Australia roaming with a Singapore IP and a high-speed allowance that resets each day. It suits short trips when you want to manage daily usage.
Why choose Australia daily?
•
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 daily allowance.
•
Daily allowance resets the next day: Choose 500MB, 1GB, 2GB, or 3GB per day. After that day's high-speed data, service continues at about and returns to high speed the next day. 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 1–10, 15, 20, 25, or 30 days, as shown on the page.
•
Who should choose this / switch: Choose this to pick your own daily allowance. For one shared allowance, switch to Australia total data. 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.
