Kolet does not provide a Saint Martin eSIM that includes a phone number or SMS capabilities. Travelers who need a local number or SMS service will only have access to data‑only plans from this provider.
Even with a data‑only plan, popular VoIP applications such as WhatsApp, Telegram, and iMessage can still be used over the internet for voice and messaging purposes. However, some destinations may restrict or block these services, so it is advisable to confirm that the apps you rely on are available in Saint Martin before purchasing a plan.
