Roambit does not offer a Grenada eSIM that includes a local phone number or SMS capability. The provider sells only data‑only eSIM plans for Grenada, so travelers cannot receive or make traditional voice calls or text messages through the eSIM.
Travelers who need to communicate can instead use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. Note that some destinations may block or restrict access to specific apps or VoIP services, so it is advisable to confirm that the apps you rely on are accessible in Grenada before buying a plan.
