English
An eSIM for Australia is a digital data plan for the phone you already own. There is no physical SIM card, no airport lines, and no passport needed. Your plan is ready on your SIMAREA account before you even leave home.
It works safely alongside your normal SIM. You keep your own number for calls and important text messages. Your data goes through the SIMAREA plan. Just turn off data roaming on your home SIM to avoid high bills.
Coverage comes from Optus and Telstra, depending on the plan. Your phone connects when you arrive and, on a plan with more than one network, moves to the stronger signal.
If you stay longer, top up your current plan with more data. You do not need to buy a new one.
What it is not: a local phone number. If you need one for verification codes, see virtual numbers for Australia.
Travel eSIM for Australia
5GAn eSIM for Australia gives your phone mobile data on Optus, or on Telstra and Optus together on the plans with an Australian IP address. Install it before the flight; most plans start counting days only once you connect in Australia.
The unlimited plan is the day pass we feature for Australia: after its daily full-speed allowance it keeps you connected at a lower speed, and it is billed per day for the days you choose. Fixed plans are one price for the term shown. Nothing on this page is an estimate.
How to get mobile data in Australia
Install it at home before you go. Some plans here start counting at installation, so check the line under the price for the plan you pick.
Pick eSIM plan
Choose how long you are there. The day pass is billed per day, so the term is yours to set.
Pay, then scan
Charged from your balance, which you top up with crypto. Your QR code is in your dashboard once the order is paid.
Turn it on when you arrive
Turn on data roaming for your SIMAREA plan when you arrive, and it joins a partner network.
What to know about an eSIM for Australia
The specifics that decide whether a travel eSIM is useful once you're actually there.
More than one network on some plans
Plans here use Optus and Telstra. Some plans have more than one, and your phone switches to the stronger signal; the technical specs show the networks of the plan you select.
Set up before you go
No SIM card store, no passport check. Install it at home, then turn on data roaming for it when you arrive.
Hotspot sharing
Share your internet with a laptop or a friend, if your plan and phone allow it.
Keep your own number
The eSIM is just for internet. Your normal SIM still receives calls and important bank codes. You can use both at once.
Keep using the same eSIM
Staying longer? Top up the same plan with more data from your dashboard. No need for a new QR code.
If it does not work
Not installed or connected yet? Ask for a refund within 30 days of buying it. Installed but not working on any of its networks? Support helps, and refunds you if it cannot be fixed.
Optus or Telstra: the networks behind each Australia eSIM
The Australia plans on this page fall into two groups, and the network is what sets them apart:
- Telstra and Optus. Most of the fixed plans: 1 GB for a week, 3 GB for 15 days, and 3, 5, 10, or 20 GB for a month. They list both operators, so your phone can register on whichever it finds where you are. These are also the plans with an Australian IP address, covered in the next section.
- Optus only. The smallest plans (100 MB and 500 MB for a week), the two 50 GB plans, one for a month and one for 180 days, and the day pass.
On these plans both Optus and Telstra are listed as 5G, so you get 5G where the operator has built it and 4G/LTE everywhere else. To confirm which group a plan belongs to, select it and read the Networks row under Technical specs. Questions before you pay go to support, any hour of the day.
Australian IP or a Singapore exit
Each Australia plan sends its traffic to the internet either from Australia or from Singapore, and the exit decides the IP address that websites and apps see. A plan that exits in Australia gives you an Australian IP; a plan that routes through Singapore shows a Singapore address instead.
The split follows the networks. The Telstra and Optus plans, from 1 GB for a week up to 20 GB for a month, exit in Australia and give you an Australian IP. The Optus-only plans route through Singapore: the 100 MB and 500 MB plans, both 50 GB plans, and the day pass.
Which exit you need depends on your apps. Navigation, chat, and email work the same from either. An Australian banking app, a local streaming service, or a store that prices by country may behave differently with a Singapore address, so if you use those, choose a plan whose IP address row under Technical specs says Australia.
How to choose an eSIM for Australia travel
Start from the kind of trip, then confirm the network and IP of the plan you land on.
A holiday of two or three weeks
A 15-day or 30-day fixed plan covers it, and every one of them up to 20 GB comes with Telstra, Optus, and an Australian IP. Size it by how you use your phone: the smaller sizes suit maps and messaging, while 10 GB and above leaves room for video calls and photo backups. The trip data calculator turns your habits into a number. If you'd rather not count at all, the day pass resets its allowance every day; the next section explains what happens in between.
A working holiday or a study term
The long option is 50 GB for 180 days. It runs on Optus, routes through Singapore, and tops up on the same eSIM when the data is gone. If an Australian IP matters more to you than one long term, take a 30-day plan with an Australian IP and top it up month by month instead.
A road trip away from the cities
Out of town, signal depends on which networks your plan can use. The fixed plans that list both Telstra and Optus give your phone a second network to try when the first has no coverage; the Optus-only plans and the day pass don't. Save offline maps before long drives either way: where no network reaches, no plan has signal.
Unlimited data in Australia: how the day pass works
The Australia day pass is the nearest thing to unlimited data here, with a daily limit you should know about. You get 1 GB a day at full speed. Go past it and the connection drops to 1 Mbps until the day resets, and then full speed comes back. 1 Mbps keeps maps, messaging, and email working, but it's slow for video.
You choose the number of days at checkout, and they start at your first connection in Australia. The pass runs on Optus, exits in Singapore, and can be topped up on the same eSIM.
If you need Telstra or an Australian IP as well, take a fixed plan instead. A 30-day plan of 10 or 20 GB has both, has no daily cap, and tops up when it runs low.
Australia and New Zealand on one eSIM
An Australia plan works in Australia only. If New Zealand is on the itinerary, look for the plans on the Asia eSIM page that cover 20 countries, Australia and New Zealand among them: one is sold for each term and size there, from 1 GB for a week to 50 GB for 180 days. On them, Australia runs on Optus (5G) and Telstra (4G), and traffic exits in Hong Kong. The Asia day pass and the plans for 7, 12, or 19 countries leave Australia out, so check the Plan details tab of the plan you pick: it lists every country that plan covers.
Spending most of the time in New Zealand alone? A New Zealand eSIM is simpler. For a trip with many stops, the global eSIM also covers Australia, on Optus.
Australia eSIM: frequent questions
Will an Australia eSIM give me a +61 number?
No. It carries data only, and your own number stays on your usual SIM. To keep an Australian number for weeks or months, rent one for a term from one week to twelve months; it receives SMS but can't make calls or send texts.
Can I buy and install it before my flight to Australia?
Yes. Set it up at home on Wi-Fi. A long-haul flight won't use up your days, because on all but one Australia plan they begin when your phone first joins an Australian network. The exception is the 100 MB plan for a week, which starts at installation.
Does the eSIM work in Tasmania and the Northern Territory?
The plans cover the whole of Australia; there are no separate plans for states or islands. Whether you have signal in a given spot depends on the plan's networks, Optus alone or Telstra and Optus, and on their coverage there.
Which Australia plan has the most data?
50 GB, either for 30 days or for 180 days. Both run on Optus and route through Singapore. With an Australian IP, the largest fixed plan is 20 GB for 30 days, and it can be topped up.
Which plan should I pick for Australian banking apps?
If the app checks the country you connect from, choose a plan with an Australian IP, so it doesn't see a Singapore address. Codes your bank sends by SMS still reach your usual SIM, since the eSIM only handles data.
Can I top up an Australia plan while I'm there?
Yes, on the same eSIM and without a new QR code. Each Australia plan sold here, fixed or day pass, takes top-ups. The Add more row in the Plan details tab shows it for the plan you select.
