Turkey generally offers good cellular coverage in urban areas like Istanbul, with widespread availability of Wi-Fi in hotels, cafes, and public spaces. Buying a local SIM card is affordable and easy at the airport or local shops, providing reliable internet access throughout your stay. Power outlets use the European standard 230V with type C and F plugs, so bringing a compatible adapter is recommended to keep your electronics charged.
The official currency in Turkey is the Turkish Lira (TRY). While you can exchange major currencies like USD and EUR at banks and exchange offices, it's best to do so in Istanbul to get better rates. ATMs are widely available throughout the city and typically offer good exchange rates, but notify your bank before traveling to avoid card issues. Credit cards are widely accepted in hotels, restaurants, and shops, but smaller vendors may prefer cash. Mobile payment options like Apple Pay and Google Pay are becoming more common, but it’s advisable to carry some cash for markets and local vendors.
