Prefer the app? Voyafi is on the App Store and Google Play.
Istanbul has two international airports on opposite sides of the city: Istanbul Airport (IST) on the European side and Sabiha Gökçen (SAW) on the Asian side. A Voyafi Türkiye eSIM works at both and everywhere else in the country, so you can install it before you fly and connect as soon as you land.
Network in Türkiye: Vodafone and Türk Telekom. 5G is available where the network and your phone support it.
Validity starts when the eSIM first connects to a network in Türkiye.

Facts from official sources, each with the date we last checked it.
Wi-Fi at Istanbul Airport (IST)
The airport offers free Wi-Fi with no usage cap on the “iGA WiFi” network. You log in with a one-time password sent by SMS, or you get an access code by scanning your passport or ID card at a kiosk in the terminal. Turkish Airlines passengers can also use “TK WiFi” with their ticket number, seat and surname. SMS login only works if your phone can receive international texts, so the kiosk route is the safer one for most visitors.

Wi-Fi at Sabiha Gökçen (SAW)
Sabiha Gökçen offers free Wi-Fi on its “Free Wi-Fi” network. The airport does not publish a time limit or the login steps, so expect a short registration on the welcome page when you connect.

Local SIM at the airport or travel eSIM?
Turkcell’s Tourist Welcome Pack for visitors is listed at 1,800 TL for 20 GB, 200 local minutes and 28 days (campaign valid until 31 December 2026; line-opening fees are not stated on the page, and you need your passport). A local SIM gives you a Turkish phone number. A travel eSIM is data-only, but there is no counter, no registration and no SIM swap: you keep your own number active for calls and messages.

5G in Istanbul
Vodafone Türkiye switched on 5G on 1 April 2026 in all 81 provinces and 922 districts. Whether you actually get 5G depends on your phone and on where you are, and the eSIM falls back to 4G wherever 5G is not available.
