Is international roaming free in Turkey with my European (EU) or UK SIM card?

It's a common misconception, but Turkey is not part of the European Union, meaning your 'Roam Like at Home' benefits from EU or UK carriers typically do not apply. If you use your domestic SIM card from providers like Vodafone, O2, EE, or T-Mobile DE in Turkey, you will likely incur expensive international roaming charges. HotelESIM offers a much more predictable and cost-effective solution, providing transparent data plans without hidden fees. This ensures you can stay connected affordably throughout your visit, whether you're using it as your primary connection or as a reliable backup to your hotel's Wi-Fi.
