yaySIM does not offer eSIM plans with a phone number or SMS for Bonaire, Sint Eustatius, or Saba. All plans available for these destinations are data‑only, meaning travelers cannot make or receive regular telephone calls or text messages through the SIM.
Because of the absence of telephony services, many travelers use data‑based applications such as WhatsApp, Telegram, or iMessage to communicate over the eSIM connection. However, some destinations may block or restrict particular VoIP services, so it is advisable to confirm that the messaging or calling apps you rely on are accessible in Bonaire, Sint Eustatius, or Saba before making a purchase.
