Two airports, different city connections

Istanbul Airport, IST, connects toward Gayrettepe on Metro M11, where you can change to M2 for central destinations. Sabiha Gökçen Airport, SAW, connects toward Kadıköy on Metro M4. Save the airport code from your flight and the interchange for your accommodation before boarding. Download your hotel address in Turkish alongside the final walking or taxi connection.

Trams, Marmaray and Bosphorus ferries

The T1 tram serves the historic peninsula, while Marmaray connects the European and Asian sides through its rail tunnel. Şehir Hatları ferries offer crossings including Eminönü–Kadıköy. Save the exact pier, destination and return departure rather than only a neighbourhood pin. Tip: download connections before Metro or Marmaray journeys, as signal can dip in tunnels; keep ferry tickets and meeting details ready for time on the water.

  • Sultanahmet: store your attraction reservation, entry instructions and meeting point before starting a mosque or museum visit.
  • Karaköy: mark the café or waterfront entrance where you are meeting, then save the walk from your tram stop or ferry pier.
  • Kadıköy: download your market-area meeting pin and the return sailing details before sharing food photos.
  • Grand Bazaar: save the name of the gate you enter through and your route back to the tram before exploring indoor lanes.

Istanbul-specific tip: a district can have several ferry departure points. Save the operator and pier printed on your route, especially around Eminönü, so your map leads to the correct boat.

For a Princes’ Islands outing, keep the island name, outbound pier and return timetable downloaded before leaving your hotel. Plan the last connection home alongside the ferry journey.

Practical Istanbul travel tips for eSIM users

Arriving and finding your accommodation

Istanbul Airport and Sabiha Gökçen Airport are on different sides of the metropolitan area; check your actual arrival airport before choosing a transfer.

Using maps and mobile data locally

Save your hotel location and nearby tram or metro stop, especially around Sultanahmet and the steep streets of Beyoğlu.

Day trips and connectivity planning

For Bosphorus ferries, verify the departure pier and sailing schedule; a destination name alone may not identify the correct terminal.

Before departure

Check that your phone is eSIM-compatible and unlocked. Read the chosen plan’s activation, hotspot and full-speed data conditions, save offline maps and your hotel address, and review possible charges from your usual mobile line.

Plan your onward route and longer stay

Match every country, your full active travel period and expected data use. Compare country, regional and Global options around the complete journey.
