If you want to watch cable channels on your Fire Stick, there are a few different ways to do it. One way is to download the app for the channel that you want to watch. For example, if you want to watch ESPN, you would download the ESPN app. Once the app is downloaded, you will need to sign in with your cable provider info. Another way to watch cable channels on your Fire Stick is by using a third-party service like Sling TV or PlayStation Vue. These services allow you to stream live TV without a cable subscription. You will need to sign up for an account and pay a monthly fee, but they offer free trials so you can try them out first.
