There are two steps to a channel becoming available on Roku in each geographical area.
- The channel owners must authorize the distribution of their content in that area. In many cases, the channel must license the ability to distribute the programming into that area from the actual owners of the content.
- The channel owners must create a version of their channel that runs on the Roku operating system and provide it to Roku for distribution. Each major streaming service (Roku, Amazon Fire, Google Chromecast, Apple TV, etc.) will require its own specialized version of the channel app.
From the number of posts we are seeing from Turkey in this forum with this same question, it seems likely that Amazon has not yet provided Roku with a Prime Video app that will run in Turkey. I would suggest you contact Amazon Prime about this.
