Best eSIM for 🇦🇺 Australia

Telstra’s network is your safest bet for reliable mobile coverage across Australia. It’s the largest network, covering about 2.5 million square kilometres, and generally performs well even in remote areas. Optus is a strong second, with good coverage in most cities and towns, but it can be patchier in the Outback. Vodafone lags behind on coverage, especially outside major centres.

For a 7-15 day trip needing 5-10 GB, expect to pay between $20-$40 AUD. Most providers offer prepaid travel SIMs or eSIMs. Look for options from Telstra or Amaysim (which uses the Optus network). These often include unlimited calls and texts within Australia.

Activating your eSIM usually involves scanning a QR code provided by the provider. Make sure your phone is connected to Wi-Fi before you start. Some travellers find it helps to put their phone on airplane mode for a minute after activation, then switch it off to force the network connection. If you have a dual-SIM phone, especially one from China, be aware that some models don't support eSIM. Always check your phone's compatibility before buying. The QR code is often time-sensitive, so don't scan it until you're ready to activate.

Australia has a mandatory SIM card registration law called ‘Do Not Call Register’. While this primarily affects local numbers, some providers might ask for ID verification upon activation, even for prepaid plans. This is usually a quick online process. Also, be aware that some plans might have restrictions on using your phone as a hotspot for multiple devices.

What’s the best eSIM for a short trip?

For guaranteed coverage, especially if you plan on leaving major cities, Telstra's prepaid eSIM is the top choice. It’s pricier, but the network reach is unmatched.

How much data do I actually need?

5-10 GB is usually plenty for a week or two if you’re mostly using it for maps, messaging, and occasional browsing. Heavy video streaming or large file downloads will eat data faster.

Can I use my existing phone number?

No, you’ll get a new Australian number with the eSIM. You can use apps like WhatsApp or Signal to stay in touch with people back home using your existing contacts.

Will my phone work with an Australian eSIM?

Your phone must be unlocked from your previous carrier and support eSIM technology. Check your phone’s settings to confirm eSIM capability.
