eSIM Travel Tips for St Martin
Activate before you leave Changi
Buy your HelloRoam eSIM for Saint Martin before your flight departs from Singapore Changi Airport. Scan the QR code at home, enable data on arrival, and you are connected in Marigot without hunting for a local SIM card. Pre-trip setup is especially useful here given limited telecom shop options on the island.
Keep your Singapore number reachable
On a dual SIM device, keep your Singtel, StarHub, or M1 SIM active for calls and texts from Singapore. Set HelloRoam as your data line in Saint Martin. Family and colleagues in Singapore reach you on your regular number without international charges.
The island border is open
There is no passport control between the French side (Saint Martin) and the Dutch side (Sint Maarten). Mobile signals from both sides can bleed across the open border. Watch your network indicator to confirm which carrier you are connected to, especially near the border area.
Download offline maps before you go
Download Google Maps offline for Saint Martin before leaving Singapore. The island's beach roads and hiking trails benefit from offline navigation. Download both sides of the island if you plan to cross into Sint Maarten.
Compare cost with Singtel and StarHub IDD add-ons
Singtel, StarHub, and M1 offer international data roaming add-ons. For Caribbean destinations like Saint Martin, daily roaming rates are high. A HelloRoam eSIM starting at S$1.46 typically works out cheaper per GB than a few days of Singapore carrier roaming.

On a trip to Europe, my hotel Wi-Fi was so slow and outside Wi-Fi was unreliable. I couldn’t take it anymore so I got helloroam for a few days. It was tricky to set up correctly because of the primary settings (with my original number). But I reached out to their customer service via WhatsApp. Super responsive and helpful, with specific and clear steps to troubleshoot. Appreciate having 4G roaming instead of being stuck with in and out Wi-Fi during my trip!!

Very good experience! The eSIM was easy to set up and worked great in London. It was much cheaper than it would have been to use my own operator there.
