Can I install my Saint Martin eSIM before I travel?

Yes, and it’s highly recommended. You can install your Saint Martin eSIM at home before departure by scanning the QR code and following the setup steps on your phone. The plan’s validity only starts when your eSIM first connects to a supported network on the island, so you won’t lose days before you arrive. This way, as soon as your plane lands, you can turn on data, contact your accommodation, pull up directions, and book a taxi without hunting for a SIM card at the airport.
