GigSky 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. However, common VoIP applications such as WhatsApp, Telegram, and iMessage can normally be used over the data connection for voice and text messages. Some destinations may block or restrict access to certain apps or VoIP services, so it is advisable to verify that the applications a traveler relies on are available in Turks and Caicos Islands before purchasing a data‑only plan.
