Airalo Europe eSIM Overview
Airalo is a well-known global eSIM brand with a huge user base, and a popular choice for Europe travel. ZenSim, meanwhile, is an Australian company offering cheaper plans (20GB for A$45 vs A$68.50 for example), stronger customer support, and a higher 4.9/5 rating on ProductReview. While both brands work well for basic usage, Airalo often relies on lower-tier network routes and charges more so I mean, ZenSim seems like a no-brainer but let's compare.

The nitty gritty
FAQs
Airalo does not offer Australia-based customer support rather they are global. All support is handled through its global ticketing system inside the app. ZenSim, on the other hand, is an Australian company with local support and more responsive help channels including WhatsApp and Messenger which makes resolving issues before or during your trip a bloody breeze.
Yep! Both Airalo and ZenSim allow unlimited hotspotting on their Europe eSIMs. Keep in mind on unlimited plans there are daily limits in place of 3GB/day, and obviously on a capped plan ie. 10GB if you use up the 10GB your data and hotspotting will no longer work.
Airalo is a well-known global eSIM brand, but its rating sits at 3.9/5 on Trustpilot. ZenSim has significantly stronger customer satisfaction, with a 4.9/5 rating on ProductReview.com.au, reflecting consistently good feedback on speed, reliability and support - in other words we're very Zen.
Airalo often routes its Europe traffic through lower-tier network paths, which can lead to congestion during busy times. This can cause slower speeds or less stable performance in crowded areas. We have tested better real-world speeds in Europe with ZenSim because it connects through higher-quality network routes.
Both brands make installation simple with QR codes and in-app guidance which is great. The main difference is that if you have an issue the ZenSim’s customer service is very highly rated, they also provide refunds for failed installations or if you're unable to use the eSIM.
ZenSim is a lot more affordable for Europe data. Airalo’s 20GB plan is A$75, while ZenSim’s equivalent is A$45 and Airalo’s unlimited 30-day plan costs A$111, whereas ZenSim offers the same length unlimited plan for A$89.
Yes. Airalo’s unlimited Europe plans include 3GB of high-speed data per day. After that, speeds are reduced. ZenSim follows a similar 3GB/day structure which is common among unlimited plans. Most providers have the caps, but some choose not to disclose it which is not great as you don't know what you're buying.
No - Airalo doesn’t work on every device. Both ZenSim and Airalo use eSIMs and only support phones that are eSIM-compatible and fully unlocked. Most newer iPhones, Google Pixels and Samsung Galaxy models work fine, but older devices or phones purchased through certain carriers may not support eSIM. Best to check our eSIM Compatability Checker in the main navigation at the top of the screen. Also, if your phone is not compatible ZenSim will offer you a full refund (Airalo will not).
