Japan eSIM FAQs
Very true! Not only that, you can refer as many people as you like to buy our Japan eSIM, you'll earn a A$5 voucher for each referral - and they will also save A$5 on their order.
There's a couple of things to be aware of, firstly they have to be a new customer for this to apply, and you as the referrer can only use one A$5 voucher per order if you happen to refer a whole lot of friends.
You can view your referral performance and grab your referral URL in the ZenSim app. Visit our terms for more info.
Absolutely! Our Japan travel eSIMs include an unlimited data option for either 10 or 30 days - perfect for staying connected without stress. Whether you're navigating Tokyo or uploading reels from Kyoto, unlimited data means no limits. Travelling longer? You can easily extend or top up your Japan eSIM through the ZenSim app.
Yep! 99% of our eSIMs can be topped up within the ZenSim app with just a couple of clicks. If you run out of data, need more days, or you even want to add a new destination to the same eSIM, you can do all of this in the top up section in the Zen Garden in the app.
Log into the app, navigate to the Zen Garden to find your Japan service, and you will see a button to up your eSIM right there.
Top up plan options: Japan top up plans are the same as the plans on the website except with a 10% discount!
Extending a long trip: If you're travelling to Japan for more than 30 days, you can add as many top ups as you need to your first eSIM to extend the days and data you have. Each top up will only take effect when the previous eSIM is expired so you can purchase the top ups any time you want without worrying about overwriting your existing plan.
Multi country top ups: You can now add multiple countries to most of our eSIMs via top up, so if you're in Europe for example and are stopping over in Dubai on the way home, you can add a Dubai top up to your Europe eSIM so you don't need to reinstall anything. Alternate country top ups will only activate when you arrive in the new country.
