Will my eSIM work as soon as I land in Sint Maarten?

Yes — install it at home on Wi-Fi before you fly, then switch the line on when you land. It joins a partner network in Sint Maarten automatically, usually before you reach baggage claim. Your days only start counting at that first connection.

Do I keep my own number and WhatsApp in Sint Maarten?

Yes. This is a data-only eSIM that runs alongside your home SIM. Your number stays active for calls and texts, and WhatsApp keeps working on your usual number the whole trip.

When do my days start counting?

Only when the eSIM first connects to a network in Sint Maarten — not when you buy or install it. Buying ahead of your trip is completely safe.

Which phones work with a Sint Maarten eSIM?

Most phones from 2018 onward: iPhone XS and newer, Samsung Galaxy S20 and newer, Google Pixel 3 and newer, plus many recent Xiaomi, Oppo and Motorola models. Your phone must also be carrier-unlocked — check yours in 30 seconds on our compatibility page.
