Once your Roku device is ready after the setup and activation process, you can visit the channel store aka streaming channels option on your TV. This is the gateway to more than 4000 channels and apps which are both free and paid. However, some channels do not appear on the channel store and you may have to add them as a private channel. Get iTunes on Roku devices using the private channel code ITPC. For further details on how to get this done and for their activation processes, you can contact us at our toll-free number- +1-844-370-7600.
