Turkey eSIM guide — Istanbul, Cappadocia and the Turquoise Coast

14 September 2026·Proost eSIM

Turkey spans two continents and an extraordinary range of experiences

Istanbul's bazaars and mosques, Cappadocia's hot air balloons over otherworldly landscapes, and the Turquoise Coast's beaches — Turkey rewards travellers who cover some ground.

How much data

5GB for a week covers navigation, translation, and typical social media use. Istanbul's public transport apps and ride-share services both rely on a live connection.

Where it matters most

Istanbul's old city streets can be confusing even with a map — Google Maps genuinely earns its keep here. In Cappadocia, booking balloon rides and checking weather conditions (balloons are weather-dependent) both need live data.

Tips for Turkey

BiTaksi is the local ride-share app, widely used and often easier than flagging a taxi

Google Translate's camera mode is genuinely useful for menus outside the main tourist areas

If your itinerary includes Cappadocia, coverage there is solid in Göreme and the main towns, though patchier out among the valleys themselves
