Help getting started with Roku devices, including setup, connecting your device to your TV, linking a Roku device to your account at my.roku.com/link, adding channels, subscribing to services, and more.
You should be able to, but the content you can view may be quite limited. Many channels have geographical limitations. The IP you connect through will give your location, so you may only be able to see the channels available in Turkey. Plus the location of the IP you used when you set up your account may impose some limitations as well that may keep you from even downloading the channel apps for non-US channels.
