Billion Connect does not provide any Guyana eSIM plans that include a local phone number or SMS capabilities. The available options from this provider are purely data‑only eSIMs for use in Guyana.
Travelers who need to make calls or send messages can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should verify that these services are accessible in Guyana before purchasing, as some destinations may block or restrict specific apps.
