Billion Connect does not offer any eSIM plans for Jamaica that include a local phone number or SMS capability. The only eSIMs available from this provider for Jamaica are data‑only plans; travelers can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection for voice and messaging. However, some destinations may block or restrict access to these services, so it is advisable to verify that the apps you need are accessible in Jamaica before purchasing a Billion Connect plan.
