If you get an activation warning on iPhone when installing before arriving, that’s normal - check our eSIM Troubleshooting Guide for details.

Add more countries: Many of our eSIMs now support multi country top ups. For example, if you're using a Europe eSIM and have a stopover in Dubai, simply add a Dubai top up and it will activate automatically when you land without needing a new installation.
Once activated in Saint Barthelemy, your eSIM typically won’t function outside that country.

You bet there is! Once you purchase an Saint Barthelemy eSIM you will be able to access your unique referral URL which you can share with your travel buds.
If they click the URL and purchase a plan they will save A$5 on their order and you will receive a A$5 voucher on your account which will be automatically applied on your next purchase (provided they are a new customer of course).
You can track your referrals and access your referral URL in the ZenSim app. Check out our terms for more info.
Only if you're on one of our unlimited plans - these come with a 3GB daily allowance, which covers the vast majority of travellers comfortably, since most people only use under 1GB a day.
Go over 3GB in a day and your speed will drop to 1Mbps for the rest of that day, resetting back to full speed at midnight.
If you've gone with a fixed-data plan (like 10GB or 20GB) instead of unlimited, there's no daily cap to worry about - you can use your data however you like until it's gone. We'll notify you before you run out, and you can top up instantly through the ZenSim app.
It won't activate the moment you buy it - your Saint Barthelemy eSIM won't touch your data or days until you actually arrive, so there's no downside to installing it in advance.
As long as it's installed beforehand, it'll activate itself the second you touch down, and that's the moment your plan officially begins.
As for running out - your eSIM expires once your data or days are gone, whichever comes first (just the days, if you're on unlimited). Buy a 30-day plan and it'll run out 30 days after arrival in Saint Barthelemy, not 30 days after purchase.
Best way to find out is with our eSIM compatibility checker - just enter your phone details and it'll confirm whether it's compatible with our Saint Barthelemy eSIM and networks.
Not 100% sure, or getting an unexpected result? Contact us and we'll help sort it out. Worst case scenario, if your phone truly isn't compatible, our refund policy gives you a full refund - so there's no risk in trying.
Yep, that's precisely why we offer a 100% money back guarantee.
Whether it's a cancelled trip, an incompatible phone, or your travel plans simply shifting, you're covered either way.
You'll find the full breakdown in our refund policy, but the gist is: can't install it, can't use it, we'll refund it in full. Simple as that.
