Is it worth getting an eSIM for Australia?
For most travellers, yes, if your phone supports eSIM. Australia plans start at $3.49 for 2 GB, and the longest lasts 365 days, which suits long stays and repeat visits. If your home plan already covers Australia at no extra cost, you may not need one.

Australia eSIMs on MobiMatter run on Optus, Telstra, and Vodafone; 5G plans are available on Optus, Telstra, and Vodafone. Optus carries the most plans. Each plan names its network, so you choose your carrier before you buy.

For Australia alone, our top plan right now is 50 GB for 30 days at $29.99 from RoamVault. If Australia is one stop of several, the top multi-country plan is 25 GB for 30 days at $24.99 from NextLink, covering 2 countries.
How much data do I need for a week in Australia?
It depends on how you use your phone. Light use (maps, messaging, browsing) takes about 0.5–1 GB a day; scrolling a lot of social video can take 2–3 GB or more. Typical use per hour:
- Instagram Reels, TikTok: 0.3–1 GB
- YouTube, Netflix at standard quality: 0.5–1 GB
- Video calls (WhatsApp, FaceTime): 0.5–1 GB
- Voice calls (WhatsApp, FaceTime Audio): 50–70 MB
- Maps and navigation: 2–6 MB
- Messaging and browsing: 50–150 MB
The cheapest Australia plan with at least 5 GB for a week or longer is 5 GB for 30 days at $4.99.
Is there an unlimited data eSIM for Australia?
Yes. Unlimited data plans for Australia start at $10.99. Many unlimited plans slow down after a daily high-speed allowance, so check the fair-use terms on the plan page before you buy.
Do Australia eSIMs support 5G and hotspot?
5G is available on 27 plans for Australia, where the local network has 5G coverage; the others use 4G/LTE. Hotspot (tethering) works on every plan, so you can share your data with other devices.
Does a Australia eSIM come with a phone number?
Most travel eSIMs, including most Australia plans, are data-only and have no local number. You keep your usual number on your main SIM for calls, texts and WhatsApp. Plans that include a number or minutes say so on the plan page.
Will my phone work with a Australia eSIM?
Yes, if it supports eSIM and is not locked to a carrier. To check, dial *#06#: if an EID number appears, your phone supports eSIM. Most iPhones from the XS/XR on, Galaxy S20 and later and Pixel 3 and later do, except most models sold in mainland China and some sold in Hong Kong and Macao.
Can I keep my own SIM and WhatsApp while using a Australia eSIM?
Yes. Your eSIM and your main SIM can be active at the same time. Use the eSIM for mobile data with data roaming on for that line, and turn data roaming off on your home SIM to avoid charges. WhatsApp keeps working on your usual number.

Mentions AustraliaPurchased eSIM in Australia and set it up in Azerbaijan. Having never used an eSIM before, I had a few ‘user issues’. These were sorted out very quickly via email and me sending a screen shot of my ‘attempted’ setup. Technician got back to me in very short order with some simple instructions and now all good. Great efficient service.

I highly recommend using MobiMatter’s eSIM! I had some problems activating it and couldn’t figure it out on my own, but the MobiMatter team helped me very quickly and explained everything clearly and in detail. Thanks a lot to their support, I was able to activate it and get connected. Great customer service! 😊

Awesome service. I have traveled back-and-forth between the United States and the Philippines and this app has not let me down. I strongly suggest that you check your data roaming option so this way you don’t mess up what you need to do.

I’ve been travelling around SE Asia for the last 7 months, covering 6 different countries, and this app has been amazing throughout when needing to change eSIM. Very easy set-up when buying one and if you in fact are having some troubles, contacting the support team and talking through email takes no time at all. I was having some difficulty with an eSIM in Vietnam since my phone was not finding a signal no matter what I did - their support team helped me and guided me on different ways to fix it. Thank you!!
