Sydney eSIM: Arriving at Kingsford Smith
Australian identity checks come before a local prepaid line activates, and a roaming profile is not one of those. Your Sydney eSIM runs on the Optus network and carries data only. You turn its data roaming on yourself after landing.
12 plans for Australia, from 1 GB at $4.49 to 20 GB at $20.99, plus 6 unlimited-data tiers. 5 GB for 30 days costs $8.99 — the cheapest of 7 in Oceania, against a $28.99 median. Our retail prices from the operator catalogue, checked 13 September 2026.

Landing at Sydney Kingsford Smith Airport
The phone will not connect on its own after you land at Sydney Kingsford Smith Airport. You install the eSIM over Wi-Fi before departure, scanning the QR code just once. On the ground, you switch data roaming on for that eSIM line in settings. The control sits in the eSIM settings, under the label the line already carries. You then pick the eSIM as the line for mobile data, and Optus takes the phone. Installing a week early changes nothing, because the clock waits for first use abroad.
Which plan for Sydney
Sydney's list runs two ladders, and neither of them expires while the profile sits unused. Metered plans start at 1 GB over seven days and reach 20 GB over thirty days. The 5 GB plan runs for thirty days and cost $8.99, checked 5 September 2026. Unlimited plans span three days to thirty, and a fifteen-day plan was priced at $44.99 on that date. Every profile recharges online, and the credit you add to it carries no expiry. A top-up therefore extends the trip without installing a second profile on the phone.
The Australian rule that reaches you
Australia's identity rules stop short of the roaming profile sitting in your phone. Identity checks are mandatory in Australia before a local prepaid line will activate. A roaming profile is not a local prepaid line, so that check never starts for you. The country page found no confirmed trap that reaches a traveller's data eSIM here. You buy the profile abroad, and no local registration follows it into Sydney.
An empty APN field, and Optus behind it
No access point name is recorded for Australia on either platform. Optus takes the phone without a typed value of any kind. So an Android handset needs nothing entered that an iPhone does not. If data stays dead, the roaming switch is where to look first. There is no second Australian partner network on this profile. Both facts were read on the Australia entry, checked 5 September 2026.
