MobiMatter does not provide a Sint Maarten eSIM that includes a local phone number or SMS capability. All of the plans sold by MobiMatter for Sint Maarten are data‑only, meaning they give you internet access but no built‑in voice or text messaging service.
Travelers who need to make voice calls or send text messages can use over‑the‑top (VoIP) applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict certain VoIP services, so it is advisable to check that the apps you rely on are accessible in Sint Maarten before purchasing an eSIM.
