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.

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.
Tips for Getting the Most Out of eSIM Promo Codes
Start with the TCM links on this page rather than hunting for a code elsewhere. Most of our partner discounts – like SIMOTCM10 for SimOptions, TCM10 for Ubigi and Nomad, and CHAMPAGNEMILE for Holafly – apply automatically or are ready to paste at checkout, so there's no need to go searching forums for a code that's probably expired anyway.
Buy before you leave Australia, not after you land. Beyond the obvious hassle of setting up data once you're already off the grid, some destinations complicate things further. If you're heading to India, for example, a January 2024 government directive means Airalo and Holafly are blocked from Indian app stores and ISPs – you need to purchase and install the eSIM while you're still on home soil.
Don't assume the cheapest plan is the best value. A dirt-cheap 1GB plan sounds like a bargain until you're rationing data on day three of a two-week trip. Work out roughly how much data you actually use in a normal week at home – maps, messaging, a bit of social media – and buy accordingly, rather than defaulting to the smallest (or largest) plan on offer.
Some providers offer an extra discount just for signing up to their newsletter – Amigo, for instance, knocks 15% off simply for supplying your email. It costs nothing but an inbox subscription you can unsubscribe from later, so it's worth doing if you're already planning to buy.
Always test your eSIM before you actually need it. Install it and confirm it connects while you're still on home WiFi, ideally a day or two before departure rather than at the departure gate. It takes two minutes and means you're not troubleshooting a dead connection the moment you land somewhere unfamiliar.
If you're travelling to multiple countries on one trip, do the maths on regional or global plans versus buying local eSIMs for each stop. A regional plan is usually more convenient, but if you're spending most of your trip in one country with only a day or two elsewhere, a local eSIM for the main destination plus a small top-up for the rest can work out cheaper.
Finally, keep your physical Australian SIM active if your phone supports dual SIM (most do). Your Aussie number stays reachable for calls and texts while all your data runs through the cheaper eSIM – no need to give anyone a temporary number or risk missing something important from home.
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.
