No, BetterRoaming does not provide an eSIM plan for Sint Maarten that includes a phone number or SMS capability. The only plans they offer for this destination are data‑only, so travelers cannot make regular mobile calls or receive SMS texts directly through the eSIM.
Travelers who need voice or messaging can still use internet‑based services such as WhatsApp, Telegram, or iMessage over the data connection, but they should check that the apps they rely on are accessible in Sint Maarten before purchasing, as some destinations may block or restrict certain VoIP services.
