Frequently Asked Questions
What is the cheapest eSIM for Australia?
The cheapest Australia eSIM on MobiMatter costs $3.49 for 2 GB, valid for 15 days. Prices come live from 8 vetted providers and change often; the price on this page is the current one.
Is it worth getting an eSIM for Australia?
For most tourists and business travellers, yes, if your phone supports eSIM. Australia plans start at $3.49 for 2 GB, and you install the eSIM before you fly, so you have data when you land, without queuing for a tourist SIM at the airport. If your home plan already covers Australia at no extra cost, you may not need one.
Which networks do Australia eSIMs use?
Australia eSIMs on MobiMatter run on Optus, Telstra, and Vodafone. Every plan names its network, so you can choose the carrier you prefer before you buy.
Which eSIM is best for Australia?
Our best plan for Australia right now is 50 GB for 30 days at $29.99 from RoamVault. We rank plans on quality and value for money, and this one comes first in the list.
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 models sold in mainland China.
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.

What our customers say
5.0
Purchased 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've tried a few eSIM apps and MobiMatters is the best. They have real customer support, lots of packages, and the service has worked very well in Australia, Singapore, Montenegro and other places. I highly recommend them.

The cheapest eSIM app I’ve found so far. I thought I had made a mistake while installing the eSIM, so I contacted customer support. They replied to my email within just 3 minutes and helped me right away. I also had no problems with the internet connection. Overall, a great experience!

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.

Used this app for mobile data while in Malaysia for a few days last week. I rate it 10/10 for ease of use, affordability and for effectiveness too. After 5 days of regular usage, I still have 8GB left out of 10GB

I have been using it for about 2 years and I am very satisfied. I used it in Greece, Bulgaria, and Romania, and I experienced internet speeds that I haven't seen in Turkey.
