Why ZenSim over Ubigi?
Ubigi is a well-known travel eSIM provider with plenty of data options, but their site can be confusing and they don’t show AUD pricing, which can lead to bank fees. Their “unlimited” Japan plan is also capped at 60GB for the whole month, so it’s not truly unlimited.
ZenSim keeps things clearer with transparent pricing, daily fair-use caps that reset every night, unlimited hotspotting, and easy multi-country top-ups in the app. With better reviews, friendlier support, and cheaper key plans like 30-day unlimited at A$94.50 vs Ubigi’s A$106, ZenSim offers better value for Aussie travellers.

FAQs
Sure, Ubigi is a well-known travel eSIM provider with a wide range of plan sizes in Asia. However, if you want to save on the plan prices, care about customer reviews, don't want your unlimited to be capped at 60GB for the month, or want to support an Aussie company, then ZenSim is the one for you.
Mainly because ZenSim is cheaper across the most common plans and comes in with a higher customer review rating which matters! On top of that, ZenSim offers unlimited hotspotting, clear daily fair-use caps that reset nightly, transparent AUD pricing, and friendlier Aussie-based support.
Ubigi’s unlimited 30 day plan is capped at 60GB for the entire month, so it behaves more like a 60GB monthly pack than unlimited. ZenSim has a speed cap of 3GB/day on unlimited plans which equates to 60GB for the month but the difference being it resets every day. So you have unlimited access every single day regardless of the usage the day before.
Yep! Both allow hotspotting in Japan and both have no limits on how much you can hotspot.
Both providers connect to strong Japanese networks though you’ll get better overall value with ZenSim thanks to cheaper pricing.
Yep! ZenSim plans across the 3 plans we compared (10GB, 20-25GB, Unlimited) for 30 days are all cheaper than their Ubigi counterparts. For example Ubigis unlimited plan comes in at A$106 vs ZenSims which is A$94.50.
