iRoamly does not offer 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 for the destination. However, they can still use popular VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection to make calls and send messages. It is advisable to confirm that these apps are accessible in Turks and Caicos Islands before purchasing, as some destinations may block or restrict certain VoIP services.
