Billion Connect does not provide Grenada eSIM plans that include a phone number or SMS capability. Travelers who plan to use the service in Grenada will receive only data‑only access. To keep in touch, popular VoIP applications such as WhatsApp, Telegram, and iMessage can generally be used over the data connection for voice and messaging. However, some destinations may block or limit certain apps or VoIP services, so it is advisable to confirm that the apps you rely on are accessible in Grenada before purchasing.
