Best eSIMs for Australia: Travel to Australia

If you would rather not track data usage at all, Sim Local also offers unlimited plans with a genuine 10GB of full speed data a day before any throttling.

An eSIM is a digital SIM built into your phone. Instead of finding a shop and swapping a physical card, you install a small profile by scanning a QR code before you fly. It sits alongside your existing SIM, so your home number stays active for calls and texts while the eSIM handles data in Australia.

With an eSIM you can access reliable mobile data without the hassle of physical SIM cards or roaming charges. International providers like Sim Local, Saily, Airalo and others let you download an eSIM plan before your plane leaves the runway, so you land in Australia and connect instantly, bypassing the search for a physical SIM card in a store.

Here is what to consider when choosing an eSIM for your trip to Australia.

• Network coverage: Telstra generally provides the widest coverage, especially in rural regions, while Optus and Vodafone are strong in urban areas.
• Data requirements: select a plan that matches your actual usage to avoid paying for data you will not use, or running short partway through the trip.
• Validity period: match the plan's validity with the length of your stay to keep connectivity uninterrupted throughout.

Before purchasing an eSIM, check that your device is eSIM compatible and unlocked for use with international carriers. Activating the eSIM before take off means you connect the moment you land in Australia.

Sim Local's Australia eSIMs connect to trusted local networks including Telstra and Optus, the same infrastructure a local SIM card from those carriers would use. That is the same network access independent reviewers point to when recommending Sim Local for Australia, since it means genuinely local coverage rather than a weaker international roaming connection.

Is it your first time in Australia? For most tourist trips of one to four weeks, the 10GB or 20GB fixed plans cover typical use, maps, messaging, social media, and some streaming with hotel Wi-Fi in the evenings. If your trip includes remote areas such as the Outback or Daintree, the Three UK plan's wider roaming coverage or Sim Local's own network access via Telstra both hold up well outside major cities, since Telstra generally has the widest rural reach of Australia's networks.

For UK travellers, buying an eSIM before you fly means you skip the search for a SIM shop after a long haul flight entirely. Buy your plan on simlocal.com while still in the UK, install it on Wi-Fi at home, and it activates the moment you land, all while your UK SIM stays in your phone for calls and texts on your normal number. For the fuller comparison aimed specifically at UK travellers, including how this stacks up against buying a physical prepaid SIM on arrival, see our prepaid SIM card Australia guide.

• Check your phone supports eSIM and is unlocked for international carriers.
• Buy your Australia plan on simlocal.com and you will get a QR code by email.
• Install it on Wi-Fi before you fly, so it is ready before you board.
• Set the new eSIM as your data line once you land, and keep your home SIM active for calls and texts.

If it does not connect straight away, check the eSIM is set as your active data line, confirm data roaming is switched on for that line specifically, and restart your phone. This resolves most connection issues after landing.

It depends on your trip. Sim Local's 20GB plan suits most month long trips, the unlimited plans suit heavier data use or longer stays, and the Three UK plan is worth considering if your trip includes other countries on the way, since it bundles in roaming across more than 70 destinations.

Yes. Buy and install your Sim Local eSIM before you fly from the UK, and it activates the moment you land in Australia, with your UK SIM staying active for calls and texts the whole time.

Sim Local's fixed data plans (5GB, 10GB and 20GB, all valid for 30 days) are built around typical trip lengths for tourists, and the unlimited plans suit longer or heavier use trips without needing to track data along the way.

You do not need to remove your physical SIM at all. An eSIM installs alongside it, so you simply set the new eSIM as your data line once it is active, while your existing SIM stays in place for calls and texts.

Most modern smartphones support eSIM, including iPhones from the XS onward and recent Android flagships such as the Samsung Galaxy S20 and newer or Google Pixel 3 and newer. Check your phone's settings or use an eSIM compatibility checker before you buy.

The momentum behind eSIM is moving quickly. Apple is now making iPhones that are eSIM only in some markets, with no physical SIM card slot at all. Check out Sim Local's Australia eSIMs now.
