📶 イスタンブールでSIMカードやeSIMは必要ですか？旅行者向けガイド

Staying connected while exploring the vibrant streets of Istanbul can make your trip easier, safer, and far more convenient. Whether you’re navigating the tram system, checking restaurant reviews, or sharing your Hagia Sophia selfies, having mobile data is a must. But what’s better for travelers—an eSIM or a physical SIM card? This guide breaks it down.

📱 SIM Card vs. eSIM: What’s the Difference?

eSIM (Embedded SIM)
If your phone supports eSIM, this is the most hassle-free option. You can download a mobile plan before you even arrive in Turkey, skipping lines at airport kiosks. eSIMs are ideal for short trips or those who want quick setup and flexibility.

Physical SIM Card
For travelers with phones that don’t support eSIMs—or those who prefer traditional SIMs—physical SIM cards are available all over Istanbul, especially at the airport and in city centers like Taksim or Sultanahmet. You’ll need to show ID and your phone must be unlocked.
