Airalo vs Holafly vs ZenSim in Europe for Aussies
Chock-full of cobblestoned castles, whimsical villages, and panoramic alpine peaks, Europe is a must-visit destination for globe-trotting Aussies. As most savvy travellers know, the best way to stay connected during a care-free European odyssey is with a travel eSIM.
In this post, we’re comparing the eSIM industry’s two biggest players, Airalo vs Holafly. We’ll also introduce a low-cost underdog, the lesser-known but exceptionally well-priced ZenSim.

Why Get a European eSIM
Let’s face it. Most Aussies rack up the country count on a whirlwind Euro trip, bouncing between nations in rapid succession. While the Schengen Agreement makes border crossings a breeze, staying connected can get complex.
The Old World continent comprises 40+ countries, and locally purchased SIMs won’t work in all of them. Europe Travel eSIMs offer an alternative, but come at the cost of convenience – you must find a provider and register upon arrival. Global roaming is an option, though low data limits and sky-high surcharges stifle value.
Enter the Europe eSIM. Eurotrippers can view prices online and install a plan within minutes – no stuffing around comparing telcos on arrival.
Airalo vs Holafly vs ZenSim Price Comparison
As big-name brands with well-established customer bases, Airalo and Holafly are the most recognisable eSIM providers. While both offer great products, they don’t always deliver the best value. Smaller players, such as ZenSim, provide an exceptional experience at a lower cost.
We’ve combed the fine print to compare features and costs. To keep things fair, we’re looking at three plan types: 10GB, 20GB, and unlimited.
Disclaimer: Prices and exchange rates are subject to change.
ZenSim Europe Travel eSIM
One few Australian-owned travel eSIM brands, the ZenSim travel eSIM for Europe provides outstanding value. Its 30-day plans in the 10GB, 20GB, and Unlimited categories beat most competitors on price, including well-established brands like Airalo and Holafly.
But budget doesn’t always mean bad. Covering 39 European nations, ZenSim is a top low-cost option for Aussies venturing off the beaten track. Customers can access friendly, responsive support via WhatsApp or email.
A broad range of plans caters to 10-day and 30-day trip durations. ZenSim also lets you add extra days and non-European countries. Fancy a stopover in Thailand to break up the arduous long-haul flight? No need to sort out a new eSIM.
Hotspotters will be happy that, unlike many competitors, ZenSim offers unlimited tethering. Power users on an unlimited plan will get a generous 3GB per day before data throttling.
ZenSim has a stellar ProductReview score of 4.9/5, a testament to its connection speed and reliability. That’s largely thanks to partnerships with top-tier telcos.
- 10GB: A$35 ($22 USD) for 30 days
- 20GB: A$45 ($29 USD) for 30 days
- Unlimited: A$89 ($57 USD) for 30 days
Airalo Europe Travel eSIM
Covering 42 countries, the Airalo Europe eSIM gives Aussies the freedom to explore. However, upon testing, we found ourselves connected to lower-tier networks with suboptimal speeds. Standard social media use was okay, but data-intensive tasks presented problems.
Customers can top up their balance using the user-friendly app, which is available in multiple currencies and languages. The app receives good ratings on the App Store (4.7/5) and Google Play (4.6). However, the brand also has an unimpressive Trustpilot rating of 3.9/5, suggesting quite a few unhappy campers.
Airalo is one of the more flexible providers in Europe, offering a dizzying array of plans with differing data limits and durations. But it’s also pretty pricey, especially compared to low-cost alternatives like ZenSim.
- 10GB: A$56.50 ($37 USD) for 30 days
- 20GB: A$75 ($49 USD) for 30 days
- Unlimited: A$101 ($72.50 USD) for 30 days
Holafly
The other big-name eSIM brand is Holafly, which currently covers 33 European countries. This provider isn’t fond of data caps, going all in on unlimited plans.
While no 10GB or 20GB Europe travel eSIMS are available, customers can choose the exact number of days they want on an unlimited plan. That could provide good value because you don’t have to pay, for example, for 30 days of data on a 20-day trip,
Holafly has a high Trustpilot rating of 4.5 / 5. The downside, however, is that Holafly's unlimited data plans aren’t that cheap. It's more costly than many eSIM providers, even with its flexible pricing structure.
Connection speeds are generally pretty quick. However, you’re limited to 500 MB per day when hotspotting, which isn’t ideal for remote workers. Also, the “Fair Use” policy is far from transparent regarding maximum daily limits. Many social media users believe there are better options than Holafly for Europe.
- 10GB: Not available
- 20GB: Not available
- Unlimited: A$117 ($74.90 USD) for 30 days

|---|---|---|---|---|
| ZenSim | A$35 ($22 USD) | A$45 ($29 USD) | A$89 ($57 USD) | 39 countries; Australian-owned; unlimited hotspotting; reliable networks, non-Euro top-ups, 4.9/5 ProductReview rating |
| Airalo | A$56 ($37 USD) | A$75 ($49 USD) | A$101 ($72.50 USD) | Widest coverage with 42 countries; easy-to-use mobile app; large range of plans and durations |

What Is an eSIM
Short for “embedded SIM,” the travel eSIM is a programmable SIM card built into your smartphone hardware. As it's digital, you can download and install new plans without installing a physical SIM card.
Most smartphones made in the last 5 years support eSIMs. See our eSIM compatibility checker to confirm.

The Benefits of an eSIM in Europe
eSIMs make getting connected more affordable and convenient.
Instead of battling the language barrier while comparing complex local SIM plans, you can find a good deal online. Numerous brands compete for consumer attention, making it easy to score a good deal.
Purchasing a plan in advance lets you get online immediately upon touchdown. As soon as you leave the tarmac, you’ll have access to Google Maps and all your favourite apps – forget faffing about at commission-hungry airport kiosks.
eSIMs also mean no juggling tiny plastic cards or struggling to open that annoying little tray. Setting one up online takes minutes.
For Aussies embarking on a European adventure, a good travel eSIM provides coverage across most of the continent. No more stressing whether your local EU plan includes Switzerland.
Finally, eSIMs are way more affordable than global roaming, which is fraught with tiny daily limits and eye-watering excess data charges.
What To Look For in a European eSIM
Eager to give eSIMs a crack? Don’t just purchase any old plan. Understanding the key considerations will help you snag a better deal.
Country Coverage
Some European eSIMs cover more countries than others. Once you’ve planned your route, compare your itinerary against the inclusions to ensure a seamless connection throughout your trip.
Reliability & Speed
Some cheap eSIMs cut corners by connecting you to shoddy, little-known networks with sluggish speeds. ZenSim partners with tier-one European providers, including Vodafone, Movistar, and Orange, to deliver the best coverage possible.
Customer Service
If your connection starts playing up mid-trip, the last thing you want is to wait on hold trying to get re-connected. The best European eSIMs for Australians offer responsive, helpful customer service via live chat or an app.
Data and Durations
Does the eSIM suit your data usage or trip duration? There’s no point buying an unlimited plan if you only use Google Maps, nor a 30-day plan if you’re travelling for 2 weeks. Shop around to see which suits your needs.
Installation Process
eSIMs are meant to be easy. A good provider prioritises the user during the installation process. Look for a telco that lets you download and install your eSIM through a mobile app or QR code.
Flexible Top-Ups
Aussies often end up traveling longer or using more data than planned. Flexible top-ups let you add extra data or days without forking out for a whole new plan. The most flexible providers let you add non-European countries to your plan for a stopover.
Hotspotting
If you plan to work online, share data with a mate, or watch movies on your laptop, a hotspot-friendly plan is essential. Some providers enforce strict limits or don’t support tethering entirely.
Daily Data Caps
Unlimited data plans have daily limits, usually between 1GB and 5 GB. Once you hit the limit, your connection gets throttled. Some providers obfuscate their limits within Fair Use policies.
Hidden Fees
Many providers offer a low rate upfront, then slug customers with extra fees or VAT right before checkout. At ZenSim, the price you see is what you’ll pay – no sneaky extra charges here.
Airalo vs Holafly vs ZenSim Which Is the Best Value?
