eSIM Travel Tips for St Martin
Set up your eSIM before leaving New Zealand
Buy your HelloRoam plan for Saint Martin at home, scan the QR code in your phone settings, and activate data when you land. No airport SIM card queues after a long-haul trip from Auckland or Wellington.
Your NZ number stays reachable on dual SIM
Keep your Spark, One NZ, or 2degrees SIM active for calls and texts while using HelloRoam for data. Whānau back in Aotearoa can still reach you on your regular number throughout your Saint Martin trip.
The island border is open
There is no passport control between the French side (Saint Martin) and the Dutch side (Sint Maarten). You can cross freely by road. Your HelloRoam eSIM covers the French collectivity. Keep an eye on your network indicator when crossing to the Dutch side as coverage rules differ.
Download offline maps before you fly
Download offline maps for Saint Martin in Google Maps before leaving New Zealand. The island's beach roads and hiking trails are easy to navigate offline, and signal can be weaker in hillside spots away from the coast.
Currency tips for NZ travellers
The French side uses euros. The Dutch side uses US dollars. NZ debit cards work at ATMs in Marigot. Keep some cash for smaller vendors and beach bars. Your HelloRoam eSIM keeps currency apps and banking tools running throughout your trip.

Transparency Notice
- Service Provider Name (SPN)
- That's HelloRoam you see up in your phone's status bar, not a mystery reseller name. The SPN is a standard field baked into every eSIM profile, and most travel eSIM resellers do not bother provisioning their own.
- Public Network Name (PNN)
- HelloRoam holds a registered Public Network Name, the official carrier identity filed with telecommunications authorities. HelloRoam is recognized as a licensed service provider, not a white-label reseller.
- Access Point Name (APN)
- Your HelloRoam eSIM sets its own Access Point Name automatically when it installs, so your mobile locks onto the strongest local network without you touching a single setting.
What you see is our standard retail pricing across 185+ countries, nothing marked up for the page you landed on. Plans get recommended off real traveller feedback and actual network performance, not guesswork. Unactivated eSIMs qualify for a 180-day refund.
