Best eSIM for Australia: Data From €1.99, Prepaid SIMs and Outback Coverage

Quick answer: the best eSIM for Australia

• Travel eSIM: the eSIMFOX Australia eSIM starts at €1.99 for 1 GB (7 days). 10 GB for 30 days costs €15.99, 20 GB costs €28.99, and unlimited data costs €19.99 for 7 days (prices on esimfox.com, Nov 6, 2026). It runs on the Optus and Vodafone networks, needs no ID check, and you install it at home before you fly.
• Prepaid SIM: Telstra, Optus and Vodafone sell prepaid plans to visitors. Australian rules require an ID check before a prepaid service is activated; visitors use their passport. Telstra's $15 Pre-Paid 7 Day plan comes with 5GB (4GB plus a 1GB activation bonus), about €9.36 at the ECB rate of Nov 5, 2026.
• Outback trips: Telstra says its network covers 3 million km², 1 million km² more than any other network. Australia is 7.69 million km². The eSIMFOX eSIM uses Optus and Vodafone, so for long drives through remote areas a Telstra prepaid SIM is the safer choice.
• Roaming with your home plan: availability and prices depend on your carrier. Check your carrier's Australia rate before you go.

eSIMFOX Australia eSIM: plans and prices (as of Nov 6, 2026)

These are the Australia plans on the eSIMFOX Australia product page. Prices are shown in euros.

The Unlimited 7-day plan gives you 2 GB of high-speed data per day. After that, speed drops to up to 1 Mbps until the high-speed allowance resets 24 hours later. Hotspot is supported. For trips longer than a week, the 30-day plans are the way to go; per GB, 40 GB and 50 GB are the best value.

Also visiting New Zealand or Asia? The eSIMFOX Asia and Oceania eSIM covers Australia, New Zealand and other countries in Asia. For Australia alone it costs more: 10 GB for 30 days is €19.99 there, compared with €15.99 for the Australia eSIM. It only pays off if one eSIM for several countries matters more to you than the price.

What the product and plan pages say about the Australia eSIM:

• Networks: Vodafone and Optus, with 4G or 5G where available. The eSIM connects to the strongest available partner network.
• Coverage: eSIMFOX promises a stable connection in cities and the most-visited regions; actual speed and coverage depend on location, device and network load.
• Validity: starts with the first network connection in Australia, not when you buy. So you can install it days before your trip.
• ID check: no eKYC (ID verification) required.
• Data only: no Australian phone number. Your home SIM stays active for calls and texts, and you can call over WhatsApp or other internet apps.
• Hotspot: the plan pages list hotspot and tethering as supported.
• Top-ups: when your data is used up, the connection stops and nothing is charged automatically. You top up in the eSIMFOX dashboard without installing a new eSIM.
• Delivery and support: the eSIM arrives instantly by email and in your dashboard. Support is available 24/7 via WhatsApp.

Australia SIM card for tourists: Telstra, Optus and Vodafone

All three Australian networks sell prepaid plans that visitors can use. One rule applies to all of them: according to the regulator ACMA, telcos must check your ID when you activate a prepaid mobile service. You give your name, date of birth and address. The telco checks your documents visually, uses a government service such as the Document Verification Service, or uses another method such as an existing account or a financial transaction (ACMA).

Telstra prepaid for tourists

Telstra's Pre-Paid page for travellers lists plans that last 7 days, 28 days, 6 months or 12 months. For a short trip, the $15 Pre-Paid 7 Day plan comes with 5GB: 4GB plus a 1GB activation bonus, which Telstra ties to activation and recharge dates. It includes unlimited calls, SMS and MMS to standard Australian numbers, but no international calls. At the ECB rate of Nov 5, 2026 (1 EUR = 1.6033 AUD), A$15 is about €9.36 (ECB); you pay in Australian dollars.

• eSIM or physical SIM: most plans are available as an eSIM, which needs a compatible phone, or as a physical SIM. The physical SIM is sent by mail and normally arrives in 5 days to metro areas.
• ID at checkout: an Australian passport, driver's license or Medicare card, or an international passport or ImmiCard.
• Australia only: Telstra says its Pre-Paid plans are for use in Australia only.

Telstra lists other traveller plans with time-limited offers, so check the current deals on Telstra's page before you buy.

Optus

Optus sells eSIM plans in store, online or by phone. For a new service on a phone you already own, Optus suggests its travellers SIM plan with the eSIM option. If you are based overseas, make sure your phone is not locked to your home network; otherwise you need a network unlock code from your provider (Optus). We could not find Optus traveller plan prices on optus.com.au on Nov 6, 2026, so we don't list any.

Vodafone Australia

Vodafone says visitors can buy a Prepaid Starter Pack online or from a Vodafone store when they arrive. It names stores at Sydney Airport (Mascot), Brisbane Airport and Perth Airport, and starter packs are sold in over 20,000 outlets across Australia. To activate it, you need an international passport as proof of identity (Vodafone Australia).

Coverage in the Outback: what Telstra says

Telstra says its mobile network covers 99.7% of the Australian population and an area of 3 million square kilometres, "1 million square kilometres more than any other mobile network" (Telstra). Australia's total area is 7,688,287 square kilometres, according to Geoscience Australia (Geoscience Australia). So even on the biggest network, much of the country has no mobile signal.

• Cities and the East Coast: a travel eSIM on Optus and Vodafone is fine for Sydney, Melbourne, Brisbane and the main tourist regions.
• Long drives through remote areas: the eSIMFOX eSIM does not use Telstra. If you spend days away from the big towns, a Telstra prepaid SIM gives you the widest coverage, based on Telstra's own figures.
• Always: download offline maps before you set off and expect long stretches without any signal.

Australia's 3G switch-off and Triple Zero (000)

According to ACMA, Telstra and Optus scheduled their 3G switch-off from October 28, 2024, and TPG Telecom/Vodafone had already switched its 3G network off. ACMA warns that some 4G phones may be unable to make voice calls once 3G is gone, including calls to Triple Zero (000), and that "most at risk are older 4G devices and devices that were purchased overseas" (ACMA).

ACMA's warning is about voice calls. If you rely on normal phone calls in Australia, for example with a local prepaid SIM, travel with a recent phone. Keep in mind that the eSIMFOX eSIM is data only, so calls go over your home SIM or apps like WhatsApp.

eSIM vs. prepaid SIM vs. roaming in Australia

Short version: for cities and the East Coast with data only, a travel eSIM is the simplest. If you want an Australian number or spend a lot of time in remote areas, a Telstra prepaid SIM is worth the ID check.

How much data do you need in Australia?

The data calculator on the eSIMFOX Australia page starts from about 0.5 GB per day for one device, adds a 20% reserve and rounds up to the next GB. For 7 days, that comes to about 5 GB. As a guide:

• A week in Sydney or Melbourne: 5 GB.
• Two to three weeks along the East Coast: 10 to 20 GB.
• A month or more, or a working holiday: 30 to 50 GB, or top up as you go.
• Lots of video, video calls or hotspot use for a week: Unlimited for 7 days.

How to set up your Australia eSIM

1. Check that your phone is unlocked and eSIM-compatible: list of compatible devices. According to Apple, iPhone XS, iPhone XS Max, iPhone XR and later models support eSIM (Apple Support).
2. Buy your plan and install the eSIM at home over Wi-Fi by scanning the QR code from your email. On an iPhone with iOS 17.4 or later, you can also tap and hold the QR code in the email and tap Add eSIM.
3. When you land in Australia, turn on the eSIM line, select it for mobile data and turn on data roaming for it.
4. Turn off data roaming for your home SIM if your carrier charges for roaming. Calls and texts can stay on your home SIM.
