MTX Connect does not offer a Curaçao eSIM that includes a phone number or SMS capability; only data‑only plans are available. Travelers who need to send SMS or receive calls can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. Some destinations, however, may block or restrict access to these services, so it is advisable to verify that the apps you rely on are accessible in Curaçao before completing a purchase.
