eSIM Travel Tips for St Barthélemy
Get your eSIM set up before you leave Australia
Purchase your plan, scan the QR code on your home Wi-Fi, and install it before your flight. When you touch down at Gustaf III Airport, your phone picks up Orange Caraibe or Digicel straight away. No airport kiosk, no registration queue.
Cache your maps before you fly in
Download Saint Barthelemy in Google Maps before you leave. The island is small but the narrow, winding roads benefit from offline navigation, particularly for villa rentals away from the main towns. GPS works from your phone hardware even without data.
Gustaf III is one of the world's most dramatic runways
The airport approach descends over a beach and the runway is famously short. Signal is available on the ground as soon as you land. Have your villa address or hotel confirmation saved offline before you fly in, just in case.
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 in St. Barths.
Save the emergency number offline
The emergency number in Saint Barthelemy is 112 (medical: 15, police: 17). Save these in your contacts before you travel. Emergency calls work on any available network regardless of your data balance.

Your HelloRoam eSIM connects automatically to whichever of Orange or Digicel provides the strongest signal at your location.
