Getting online in Istanbul

Istanbul has two airports: Istanbul Airport (IST) on the European side, operated by iGA, and Sabiha Gökçen (SAW) on the Asian side. Both publish a free Wi-Fi service, but the login method at IST matters if you arrive without a working phone number.

Arriving at Istanbul Airport or Sabiha Gökçen

Passport control, transport tickets and ride-hailing all go more smoothly with data already working. If you plan to rely on airport Wi-Fi instead, read the login options below first — one of them requires receiving an SMS.

Official airport Wi-Fi

iGA states that unlimited, free internet is available to passengers at Istanbul Airport. You select the iGA WiFi network and then either log in with your mobile number, entering the password sent to you by SMS, or get an access code from a terminal kiosk that scans your passport or ID card and log in with that code. Turkish Airlines passengers can also use the TK WiFi network, logging in by SMS or with ticket number, seat number and surname.

Sabiha Gökçen publishes a wireless internet service for passengers on its own services pages. Check the current instructions there before you travel.

Getting connected after arrival

The SMS login route assumes you can receive a text on arrival. If your home line has no roaming, either use the kiosk access-code option or arrive with a travel eSIM already installed, which is active as soon as you land. We publish no claims about airport Wi-Fi speed or reliability — official sources do not state them.

Paying for city transport

Istanbul's public transport runs on the Istanbulkart, the prepaid card issued through the Istanbul Metropolitan Municipality's transport system and used across metro, buses, trams, the Tünel and city ferries, with fares published by the municipality's transport directorate. Buying and topping up is a physical process at kiosks and machines, so it does not depend on your phone — but journey planning does.

Turkey's device registration rule

Turkey operates a Central Equipment Identity Register. Turkey's telecoms regulator, BTK, states that phones brought in from abroad can be used for 120 days from the date of entry without registration, and that devices not registered within that period are cut off from communication services. This applies to the handset's IMEI, not to your data plan, so neither a local SIM nor a travel eSIM changes it. It matters for long stays, not for a short trip.
