The best esim promo code for Australian travellers
A bit of research before you buy will be money well spent. The good news is that eSIM deals are generally very reasonable compared to what Australian telcos charge for roaming – but pick the wrong one and you could find yourself landing at your destination with a SIM that won't activate, or stuck crawling along on an old, slow network. Not the start to a trip you're after.
Before you purchase, think about what you actually need. Are you after a local plan for one country, or an international plan that follows you across multiple destinations? How much data do you realistically use in a day? And do you need voice calls and SMS, or is data-only fine for you?
Once you've figured that out, stick with a reputable provider – all our listed providers are solid starting points. From there it's straightforward: select your plan, pay, and you'll receive either a QR code or a download link to get your eSIM onto your device. Installation is usually quick, though the exact steps can vary slightly depending on your phone.
The one tip we can't stress enough: test it before you need it. Run a quick check on WiFi at home or just before you head through the departure gate. It takes two minutes and saves a lot of stress on the other side.
TCM has personally used Holafly, Airalo and Nomad over the years in various places and we can attest to the ease of setup and usefulness of these eSIM companies.
If you want to go deeper on how eSIMs work, Apple has a great explainer here.
Holafly
Established in 2017, in Spain, Holafly is one of the original eSIM providers that delivers prepaid data and roaming virtually anywhere in the world. Both Android and iOS phones are supported with apps that allow monitoring and usage tracking.
Plans can be customised for your travel duration and activate via QR code. Support is readily available.
Airalo
Airalo is a leading eSIM marketplace that gives travellers seamless access to mobile data worldwide without the need for physical SIM cards.
Users can browse global, regional and local data plans to save money and ensure they only pay for what they're likely to use. Again QR code activation is simple.
Airalo often has 10-15% discounts available via our deals page.
Nomad
Nomad eSIM is a digital mobile solution designed for travellers who want instant, hassle-free connectivity without relying on physical SIM cards. Users can purchase and activate eSIM data plans online, avoiding roaming fees and long searches for local SIM vendors.
Nomad plans cover 200+ countries and regions, offering flexible options from short-term travel passes to longer regional packages. The eSIM is easy to install via a QR code and supports most modern smartphones.
Nomad may not always be the cheapest, but users on the whole are satisfied with the quality of the service.
Simify
Simify emphasizes simplicity, instant activation, and competitive pricing compared to traditional roaming charges.
The Simify Europe package and the North American package represent good value for money in our opinion.
Customers can score a further 10% off when they subscribe to the Simify newsletter.
GigSky
GigSky is a real innovator in the eSIM market, offering free trials and package for cruises that cover land and sea. Combine our exclusive promo code for value for money.
GigSky covers all the major cruise companies and most likely offers better value than onboard internet packages.
Amigo
Unlock 15% off by supplying your email for the newsletter.
Global Yo
Global Yo was founded in 2022 and based in New York that offers mobile data-only eSIM plans across more than 200 countries.
It offers flexible local, regional, and global plans. Users enjoy unique perks like an in-app rewards system (YOYO$), indie films, AI celebrity guides, and travel tips.
Saily
If I had to pick an eSIM on the basis of security features alone, Saily would be it. Adblockers and malicious software control come as standard. Saily also comes with 24/7 support.
Roamless
Roamless is a strong option for travellers wanting reliable global coverage with flexible plans and a clean interface. Their eSIM plans cover many destinations (including major travel markets) with data-only or combo (data + calls/SMS) options.
Activation is via QR code or in-app, and the dashboard makes it easy to monitor usage and top up on the go.
SimOptions
SimOptions is more of a marketplace / aggregator for international eSIMs (and physical SIMs) rather than a single network operator. They provide access to a wide range of regional, national, and global eSIM plans from multiple providers across 200+ destinations.
Because it's a marketplace, support and service quality can depend on the specific provider behind the eSIM, not SimOptions itself.
Airhub
Airhub is best suited to travellers who want affordable global coverage with a mix of data and call options, all managed easily through one app.
Some plans include voice and SMS, not just data.
Jetpac
Jetpac is a Singapore-based eSIM provider that offers both country-specific and regional/global data plans, with a few travel perks that help it stand out.
If your flight is delayed (usually by 60+ minutes), Jetpac provides free airport lounge access (for you + companions) via its “SmartDelay” / “SmartPerk” feature.
Ubigi
Ubigi plans are data-only: no voice or SMS included. If you need a phone number or SMS, you’ll need an alternative or rely on VoIP messaging.
What is an eSIM?
If you've never used an eSIM before, here's the short version: it's a SIM card built into your phone. No plastic, no popping a tray out with a pin, no hunting for a SIM shop when you land. You buy a plan online, scan a QR code, and you're connected, often before your flight even lands. Here's what makes them genuinely useful for travellers…
Convenience & Flexibility – There is no need to insert or swap physical SIM cards. Rather, you can activate or switch carriers instantly through software or QR codes.
Multiple Profiles – A user can store multiple carrier profiles on a single eSIM. This is an incredibly useful solution for separating work and personal numbers on one device.
Global Connectivity – Roaming suddenly becomes far easier when you can quickly purchase and activate local data plans abroad without finding a SIM card store.
Better Security – It is harder for thieves to physically steal or clone since the eSIM is embedded. Carriers can remotely disable the eSIM profile, if your phone is stolen.
eSIM Not Working? Here's How to Fix It
Before you panic, most eSIM problems have a simple fix. Here are the most common issues and what to do about them.
My eSIM won't activate
First, make sure you're connected to WiFi when you install it. eSIMs almost always need an internet connection to activate. If you're on WiFi and it's still not working, try restarting your phone after installation. This solves the problem more often than you'd think.
I have no signal at my destination
Check that data roaming is switched on in your phone settings. This catches a lot of people out. Also confirm that the eSIM plan you purchased actually covers your destination. Some plans look global but exclude certain countries in the fine print.
My eSIM activated but the speeds are really slow
You may have landed on a lower-priority network. Go into your phone's mobile data settings and manually select a different available network to see if speeds improve. Also check whether your plan has a daily data cap that throttles speeds after a certain amount.
I ran out of data mid-trip
Most providers let you top up directly through their app, even if you have no data left – just connect to WiFi and purchase additional data. This is one reason it's worth downloading your provider's app before you leave home.
My eSIM disappeared from my phone
This can happen after a software update or factory reset. eSIMs are tied to the device but can sometimes need to be re-added. Contact your provider's support team – most can re-issue the same plan without charging you again.
The QR code won't scan
Try increasing your screen brightness if you're scanning from another device, or ask your provider to resend the activation details as a manual code instead. Most providers offer both options.
I can't find the eSIM settings on my phone
On iPhone, go to Settings → Mobile Data → Add eSIM. On Android it varies by manufacturer, but Settings → Network & Internet → SIM cards is usually the right place. If you're still stuck, your provider's website will have device-specific instructions.

Can I use an eSIM on an iPhone?
Yes. Any iPhone from the XS onwards supports eSIM, and from the iPhone 14 (US models) Apple dropped the physical SIM slot entirely. If you're on an iPhone 11 or newer you'll have no issues at all. Just make sure your phone isn't carrier-locked, as a locked device may not accept eSIMs from other providers.
Can I use an eSIM and my Australian number at the same time?
Yes, and this is honestly one of the best things about eSIMs. Most modern smartphones support dual SIM – meaning you can keep your regular Aussie number active on your physical SIM while running a local data plan on your eSIM. Your Australian contacts can still call and text you as normal, while all your data runs through the cheaper local eSIM. No juggling two phones, no missing calls from home.
What's the difference between a local eSIM and a global eSIM?
A local eSIM covers a single country – you buy it specifically for, say, Japan or Italy, and it connects to local networks there. These tend to be cheaper and often faster because they're running on local infrastructure rather than routing through a roaming agreement.
A global eSIM covers multiple countries under one plan, which is handy if you're hopping between destinations on the same trip and don't want to buy a separate eSIM for each country. The tradeoff is that global plans are usually a bit pricier per GB. If you're spending two weeks in one country, go local. If you're doing five countries in three weeks, a global plan will save you the hassle.
Do eSIMs work on cruise ships?
Most standard eSIMs don't include cruise or satellite coverage. If your eSIM does roam at sea, it can get expensive fast. If you're heading on a cruise, GigSky is worth a look – they're one of the few eSIM providers that specifically caters for cruise travel, covering both land and sea so you stay connected whether you're in port or out on the water.
How do I know if my phone is eSIM compatible?
The quickest way is to dial *#06# on your phone – if an EID number (a 32-digit code) appears alongside your IMEI, your device supports eSIM. Alternatively, head into your phone's settings and look for “Add eSIM” or “Cellular Plans” – if the option's there, you're good to go. As a general rule, most smartphones released after 2020 support eSIM, including recent models from Apple, Samsung, Google Pixel, and more. If you bought your phone overseas, it's worth double-checking as some international models have eSIM disabled.
What is an eSIM and how is it different from a regular SIM card?
An eSIM (embedded SIM) is a digital SIM built into your phone, tablet, or smartwatch. Unlike a physical SIM card, you don’t need to insert or remove it – you can activate a mobile plan instantly by scanning a QR code or using an app. It offers flexibility to switch carriers or data plans without changing cards.
How do I activate an eSIM deal on my phone?
Activation is usually simple: Purchase an eSIM plan from your carrier or eSIM provider, and then scan the QR code they provide or enter the activation code manually.
Is my phone eSIM compatible?
Most modern smartphones (like recent iPhone, Samsung Galaxy, Google Pixel, and others) support eSIM. To check compatibility: Look in your device settings for “Add eSIM” or “Cellular Plans.” Check your device model on the provider’s compatibility list.
Can I have multiple eSIMs on one phone?
Yes. Many devices allow you to store multiple eSIM profiles – for example, one for personal use and one for travel. You can switch between them easily in your phone’s settings, though usually only one or two can be active at a time, depending on your device.
