Buy eSIM data plans for Australia
Your Australia eSIM is a prepaid data plan that connects your phone to local Australia networks at full speed the moment you land — a digital SIM you install before you fly, with no queues, no SIM swap and no roaming fees.
Landing at Sydney Kingsford Smith Airport after a long-haul flight? A Australia eSIM is a data-only profile that activates the moment you reach the terminal, connecting you to the Optus (5G) network without swapping a physical SIM. Skip the roaming charges and the airport SIM queues, and step out already online. From the arrivals hall you can pull up maps, message family back home, book a ride into the city, and check your hotel before your bags reach the carousel. It is the simplest way to stay connected across a country built on long distances.

Frequently asked questions
Which mobile networks does the Australia eSIM use?
The Australia eSIM connects to the Optus (5G) network, giving you 5G data where it is available and falling back to fast 4G elsewhere. You get a local connection automatically, with no need to choose or configure a carrier yourself.
Will I have coverage outside the big cities and in the Outback?
Australia is a continent of long distances. Coverage is strong in the cities and along the populated coast, but signal naturally thins out across the Outback and the remote interior. For city stays and coastal road trips you will be well connected; if you plan to head deep inland, download maps offline before you go.
Does this plan work in other countries too?
No, this is an Australia-only plan and works within Australia. If your trip also includes other destinations, choose a regional eSIM that covers multiple countries instead of a single-country plan.
When should I set up the eSIM before arriving in Australia?
Install the eSIM while you still have Wi-Fi, ideally a day or two before you fly. The profile then activates automatically as you reach Sydney Kingsford Smith Airport, so you are online the moment you switch off airplane mode at the terminal.
Will my phone work with an Australia eSIM?
Most modern, unlocked phones support eSIM. If your device is eSIM-compatible and not network-locked, you can install the profile by scanning a QR code and keep your usual apps and settings. It is worth checking your phone's settings for an eSIM or 'add mobile plan' option before you travel.
Can I keep my own number and use a hotspot in Australia?
Yes. The eSIM runs alongside your home SIM, so you can keep your own number active for calls and texts while using the eSIM for data. You can also share that data as a personal hotspot, which is handy for a laptop or for relatives travelling with you.
