Best eSIM for Australia : detail guide
1.esimNB
✅ Top-up & hotspot avaliable
✅ Supports over 140+ countries
✅ Plans start from $1.50
2026 Update: esimNB Expands Carrier Support in Australia. Starting March 2026, our eSIMs support all major Australian mobile operators with 5G connectivity. High-speed 5G is included at no extra cost—our prices remain unchanged.
esimNB’s Australia eSIM works with three major local carriers — Optus, Vodafone, and Telstra — and all support fast 5G speeds.
This means you can expect a smooth internet experience in most Australian cities. Because the eSIM connects to multiple networks, you also get an extra layer of reliability.
If one carrier has slow speeds or weak signal in your area, you can switch to the other one, such as Vodafone, to stay online. This makes it safer than using an eSIM that depends on only one carrier.
esimNB focuses on simple, fixed-data plans with a pay-as-you-go style.
If you plan to travel to Australia for about one week, and spend about one hour every day watching YouTube videos and scrolling through Instagram, you are a medium data user.
I recommend buying the "Australia 10GB 30 Days" plan. It’s a good balance between price and data allowance, and it gives you enough room to enjoy your trip without worrying about running out of data.
10GB is enough for normal use, and if you feel you might run out, you can easily top up online without reinstalling or reactivating the eSIM.
The smallest plan starts at 1GB for 7 days, which is great for short trips, testing the service, or handling urgent needs.
The largest plan offers 50GB for 180 days, giving heavy data users and long-term visitors plenty of room.
| Destinations | Data Plans | Duration | Price (USD) |
|---|---|---|---|
| Australia | Total 1GB | 7 days | $1.50 |
| Australia | Total 3GB | 15 days | $3.50 |
| Australia | Total 5GB | 30 days | $5.50 |
| Australia | Total 10GB | 30 days | $9.50 |
| Australia | Total 20GB | 30 days | $16.50 |
| Australia | Total 50GB | 180 days | $56.50 |
For customer support, esimNB offers help through WhatsApp and email. The response time is usually between 1 to 12 hours, depending on your time zone. Luckily, the help center is quite complete, so you can often find answers to common questions on your own.
2.Holafly
2026 Update: Holafly eSIM in Australia has removed support for Telstra (2026-03-17).Now, only one carrier, Optus, is available. The price still stays the same.
Holafly is an eSIM provider known for its unlimited data plans, which charge by the day.
Their Australia eSIM starts at $3.9 per day, and the daily price becomes lower when you buy more days at once.
| Destinations | Duration | Data Plans | Price (USD) |
|---|---|---|---|
| Australia | 1 days | unlimited | $3.90 |
| Australia | 3 days | unlimited | $11.70 |
| Australia | 7 days | unlimited | $27.30 |
| Australia | 30 days | unlimited | $74.90 |
| Australia | 50 days | unlimited | $96.90 |
Holafly’s Australia eSIM has reduced the number of supported carriers in 2026. The good news is that it still keeps support for Optus, one of Australia’s major networks.
If you’re mainly staying in city centers or popular urban areas, the connection should remain stable and you’re unlikely to notice any difference. However, if your trip includes suburbs, road trips, or outdoor destinations, the coverage and signal strength may be less consistent compared to options that support multiple networks.
Compared with other providers that offer unlimited data, Holafly gives more high-speed allowance before slowing down. You won’t drop to low speeds suddenly after using only 2GB, which is common in many “unlimited” plans on the market.
However, there is one thing all travelers should know: unlimited data plans often have hotspot limits.
Holafly usually allows around 2GB of hotspot data per day, so if you need to share internet with your laptop or friends, a fixed-data plan is usually better.
Overall, Holafly Australia eSIM is a good choice if you stream videos often and want a simple option without checking data usage.
But if you are familiar with eSIMs and want better value with more control over your data — without worrying about speed drops — a fixed-data plan like esimNB’s pay-as-you-go option is likely the smarter pick.
3.Yesim
Yesim offers both unlimited data plans and prepaid data plans for Australia.
The unlimited plans are available for 1, 7, 15, and 30 days, while prepaid plans start from 10GB and above.
For first-time users, Yesim also provides a small trial option — 500MB for 3 days at $0.54, which is useful if you want to test the connection before buying a full plan.
Yesim works with Vodafone and Optus in Australia, and Optus supports 5G. This means you can expect good coverage and fast speeds in major cities.
However, Vodafone runs mainly on LTE, so the experience may not be as strong compared to Optus.
Their prepaid plans are clearly structured to encourage larger data purchases. Only the 20GB and 30GB plans come with noticeable discounts — 22% and 33%, making them more appealing for heavy users.
| Destinations | Data Plans | Duration | Price (USD) |
|---|---|---|---|
| Australia | Total 500MB | 3 days | $0.54 |
| Australia | Total 10GB | 30 days | $19.20 |
| Australia | Total 20GB | 30 days | $30.00 |
| Australia | Total 30GB | 30 days | $38.40 |
| Australia | Unlimited | 1 day | $8.40 |
| Australia | Unlimited | 7 days | $28.80 |
Overall, Yesim is flexible enough for different needs. You can choose unlimited data for convenience or prepaid plans for better control. And if you’re visiting more than one country on your trip, their global eSIM packages can also be a useful option.
4.Maya mobile
2026 Update: Maya Australia eSIM has adjusted its plans and prices in 2026. It removed small data plans like the 3GB plan and added a large 100GB plan. Plan prices have decreased by about 2 USD dollars.
Maya Mobile is one of my personal favorite eSIM providers. The main reason is their automated support system — it works fast and feels even better than Holafly in my experience.
For Australia, Maya’s eSIM connects to Optus only, but it supports 5G, which is more than enough for smooth internet in major cities. In fact, most eSIM brands for Australia rely mainly on Optus as well, so this is not really a disadvantage.
Maya offers plans from 3GB up to 50GB, starting at $5.99. Another useful feature is auto-recharge, which helps if you worry about running out of data and forgetting to top up on time.
| Destinations | Data Plans | Duration | Price (USD) |
|---|---|---|---|
| Australia | Total 5GB | 30 days | $9.99 |
| Australia | Total 10GB | 30 days | $16.99 |
| Australia | Total 20GB | 30 days | $27.99 |
| Australia | Total 50GB | 180 days | $47.99 |
| Australia | Total 100GB | 180 days | $71.99 |
Back to what I mentioned earlier — Maya’s automated support system is a real highlight. You select your issue, and their smart help tool shows the best solution along with related support articles right away. It’s simple, clear, and honestly more effective than waiting for a live agent.
5.aloSIM
aloSIM offers both fixed data plans and unlimited data plans for Australia. The fixed plans range from 1GB to 20GB, and the unlimited plans are available for 10 days or 15 days.
aloSIM uses Optus as its network partner, but the connection is LTE only, which may feel weaker compared to other providers that support 5G. This can be seen as a drawback if you care a lot about speed.
However, aloSIM comes with one unique benefit — it works together with Hushed, giving you an international phone number with $3 credit included. The credit can only be used inside Hushed, but it’s still a handy feature if you need calls or texts during your trip.
| Destinations | Data Plans | Duration | Price (USD) |
|---|---|---|---|
| Australia | Total 1GB | 7 days | $4.00 |
| Australia | Total 2GB | 15 days | $6.50 |
| Australia | Total 3GB | 30 days | $8.00 |
| Australia | Total 5GB | 30 days | $11.00 |
| Australia | Total 10GB | 30 days | $18.00 |
| Australia | Total 20GB | 30 days | $30.00 |
How to Manually Switch Your Australia eSIM Network on iPhone
If your eSIM supports more than one carrier (such as Optus and Vodafone), you can switch networks manually on your iPhone. This is useful when the signal becomes weak, or when one carrier works better in a certain area.
Follow the steps below:
- Open the Settings app
- Tap Mobile Service / Cellular
- Select the eSIM plan you are using in Australia
- Tap Network Selection
- Turn Automatic off
- Wait a few seconds — your iPhone will show available carriers
- Choose the carrier you want to switch to (for example Vodafone or Optus)
- Wait for the network to reconnect — it usually takes 10–30 seconds
Once it reconnects, you can start using mobile data again on the new network. If performance still feels slow, try switching back or testing in another location.
Where to buy an eSIM for Australia
The easiest way to buy an eSIM for your Australia trip is through online eSIM stores. You can purchase, activate, and manage the plan before you travel — no need to wait at the airport or visit a local mobile shop. Everything can be done on your phone within minutes.
One of the most popular platforms is esimNB, which offers multiple Australia plans with 5G support and coverage from major networks like Optus and Vodafone. You can choose your package based on your travel time and data needs, and after payment, your eSIM QR code is delivered instantly by email. This makes esimNB a great option if you want a smooth start the moment you land.
Many other eSIM stores also sell Australia plans, such as Holafly, Yesim, Maya Mobile, and aloSIM. Each platform offers different types of plans — some focus on unlimited data, while others provide flexible prepaid packages. Buying online allows you to compare prices, data limits, supported networks, and customer reviews before deciding which one fits you best.
If you prefer convenience and want your mobile data ready before arrival, purchasing from an online eSIM provider is the simplest and most traveler-friendly option.
How to make calls with an eSIM in Australia
Most travel eSIMs are designed for data only, which means they don’t include an Australian phone number for regular voice calls or SMS. However, you can still make phone calls easily using internet-based services.
Here are the most common ways to call with an eSIM in Australia:
1. Use VoIP apps (recommended)
Apps like WhatsApp, FaceTime, Messenger, Telegram, LINE, and WeChat let you make voice and video calls using mobile data. If both sides use the same app, calls are free.
2. Use Wi-Fi calling
If your home SIM supports Wi-Fi calling and is still active on your phone, you may be able to receive calls from your original number as long as you stay connected to the internet. This is useful for receiving bank verification codes, business calls, or urgent messages.
