Billion Connect does not provide an eSIM for Turks and Caicos Islands that includes a phone number or SMS capability. Travelers can only purchase data‑only plans from this provider. If voice or text communication is needed, popular VoIP applications such as WhatsApp, Telegram, and iMessage can usually be used over the data connection, but some destinations may block or restrict certain apps, so it is advisable to confirm that the services you rely on are accessible in Turks and Caicos Islands before buying a plan.
