Travel eSIM Saint Martin

No, our Saint Martin eSIMs only deliver mobile data. For voice or SMS, you’ll need to use an app that works over data - WhatsApp, Messenger, or other similar internet calling platforms.

Absolutely! You can install your Saint Martin travel eSIM up to 30 days before departure. Installing early means it will automatically activate once you land.

Rest assured, installing before you leave won’t start your data or count down your plan days until you arrive in Saint Martin.

If you see an activation error on iPhone when installing before arriving, you can ignore it-learn more in our eSIM Troubleshooting Guide.

No, these eSIMs only provide data access and do not assign you a phone number. To make calls, you will need to use internet based apps such as WhatsApp or Messenger.

Your eSIM will activate automatically when you arrive in Saint Martin. Though we recommend installing your Saint Martin Travel eSIM before you arrive (this is different to activating).

To do this, scan the QR code we provide or install the eSIM directly from the ZenSim app while connected to WiFi. Once you arrive in Saint Martin, your eSIM will activate automatically.

If you encounter any issues check out our eSIM Troubleshooting Guide or contact us directly ☺️

The eSIM activates when you touch down in Saint Martin - if you’ve already installed it, it should connect automatically.

Installing while already in Saint Martin works too; it will start as soon as you complete setup.

If you experience connection issues, check our eSIM Troubleshooting Guide or reach out to our support team.

If you want to avoid roaming headaches in Saint Martin, a travel eSIM is the smarter pick:

Big Savings: Our local Saint Martin eSIM data plans are priced for residents, not tourists who pay premium roaming costs.

Easy Plan Changes: Upgrade or downgrade your data allowance on the fly - no need for a new SIM.

Full Transparency: See your data usage in - app so you won’t run out unexpectedly or incur extra charges.

No, your plan only starts upon landing in Saint Martin. Installing beforehand ensures you’re ready to go as the activation will happen automatically.

You’ll need WiFi for installation, so do it before departure and this way you will be connected as soon as you arrive.

If you run into any issues, our eSIM Troubleshooting Guide can help, or contact us directly.

Yes, you can. Around 99 percent of our eSIMs allow quick and easy top ups through the ZenSim app. You can add more data, increase the days, or even include a different destination on the same eSIM right from the Zen Garden.

Open the app, go to the Zen Garden area, and you’ll see the top up button waiting for you.

Top up pricing: Saint Martin top up plans follow the same pricing as on the website, minus a 10% discount.

Travelling for a while: If your trip lasts more than 30 days, you can queue multiple top ups. None of them will interrupt your current plan because each one only activates when the previous eSIM expires.

Travelling to more destinations: Most eSIMs let you attach extra countries via a top up. For example, if you're heading home from Europe and stopping in Singapore, you can add Singapore to your Europe eSIM and it will switch on once you arrive.

Your Saint Martin eSIM is designed for use within Saint Martin, so once it's been activated there, it won’t work in other countries.

If you're visiting multiple destinations, a better option might be one of our regional Travel eSIMs that cover entire regions like Europe or Asia.

You bet there is! Once you purchase an Saint Martin 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.

Our Saint Martin unlimited plans include a 3GB daily allowance, which is more than enough for most people - average daily usage tends to sit under 1GB.

If you happen to use more than that in a day, your speed gets limited to 1Mbps until midnight, at which point your full-speed allowance kicks back in.

This only applies to unlimited plans - if you've chosen a fixed-data plan like 10GB or 20GB, there's no daily throttling at all, just use it freely until it runs out. We'll let you know before that happens, and you can top up in seconds via the ZenSim app.

Your days and data don't start counting down the second you buy the eSIM - they only kick in once you actually land in Saint Martin, so feel free to install it well ahead of your trip.

As long as it's already installed, it'll auto-activate the moment you arrive, and that's when the clock starts on your plan.

As for when it ends - your plan runs until either your data or your days are used up, whichever happens first (unless you're unlimited, in which case it's just the days that matter). A 30-day plan means it ends 30 days from your arrival in Saint Martin, not 30 days from your purchase date.

Quickest way to check is through our eSIM compatibility checker - it'll let you know in seconds if your phone plays nicely with our Saint Martin eSIM and the networks it runs on.

If anything's unclear or you'd rather double check with a human, reach out to us anytime. And if your phone ends up not being compatible, you're covered by our refund policy - full refund, no hassle - so it's worth just giving it a go.

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.
