SimOptions does not offer any eSIM plan for Grenada that includes a local phone number or SMS service. All available plans are data‑only, allowing you to connect to the internet for browsing, streaming, or other online activities. Travelers who need to make voice or text communications can use internet‑based messaging and calling apps such as WhatsApp, Telegram, or iMessage, though it is advisable to confirm that these services are accessible and not restricted in Grenada before purchasing.
