Cache your maps before you head off

The island border is open, no passport needed
There is no border control between the French side (Saint Martin) and the Dutch side (Sint Maarten). You can drive across freely. Keep an eye on your network indicator as you move around to confirm which carrier your eSIM is connected to.
Keep your Aussie number active while using local data
Most modern phones support dual SIM. Keep your Australian SIM active for calls and texts from home. Set the HelloRoam eSIM as your data line. You stay reachable on your regular Aussie number without paying international rates while your eSIM handles data on the island.
