GulfData does not provide Turkey eSIM plans that include a phone number or SMS capability. Only data‑only eSIMs are available from GulfData for Turkey. Travelers can still use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection, but some destinations may block or restrict specific apps or VoIP services, so it is advisable to confirm that the apps you rely on are accessible in Turkey before purchasing a GulfData eSIM.
