Saint Martin eSIM FAQs
Traditional calls and SMS aren’t part of our Saint Martin eSIM packages - they’re strictly data provision. To talk or text, use internet - based services (WhatsApp, Signal, etc.) with your eSIM data.
Data and plan days only kick in when you arrive in Saint Martin. Installing earlier just prepares it for activation which happens automatically when you arrive in Saint Martin.
Install over WiFi before your trip to get connected from the minute you touch down.
If you have trouble connecting, see our eSIM Troubleshooting Guide or message us for assistance.
Once activated in Saint Martin, your eSIM typically won’t function outside that country.
If you're planning to hop between countries, we recommend checking out our regional Travel eSIMs - they’re made for multi-country use and cover most major regions.
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.
No, the Saint Martin eSIM is data - only and excludes voice/SMS numbers. You’ll have to rely on data - based messaging platforms like WhatsApp or Telegram for calling.
Most ZenSim eSIMs can be topped up directly inside the app. If you ever need extra data, additional days, or want to include a new destination on the same eSIM, the Zen Garden is where you can do it.
Simply log in, tap into the Zen Garden, and you’ll find the option to top up right there.
Extending your stay: Planning to be away longer than 30 days? You can buy multiple top ups ahead of time. They activate one after another, so there’s no risk of replacing your current plan.
More than one country: Many eSIMs now let you attach extra countries through a top up. For example, while using a Europe eSIM you can add Singapore as an extra destination. It will activate automatically when you land in Singapore.
Your eSIM will activate automatically once you step off the plane in Saint Martin. We do suggest installing your Saint Martin Travel eSIM before departure (installation ≠ activation).
Installation is a breeze: scan the QR code provided or install via the ZenSim app over WiFi. Upon landing, the eSIM will activate itself.
