GigSky does not provide a Grenada eSIM that includes a local phone number or SMS capability. Travelers looking to stay in Grenada can purchase a data‑only GigSky eSIM, then use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection for voice and messaging. Some destinations, however, may block or restrict certain VoIP services, so it is advisable to verify that the apps a traveler relies on are accessible in Grenada before buying a plan.
