It’s easy to cancel Sling TV if you want to avoid being charged more at the end of your discounted subscription - or just no longer wish to use the streaming service. Just head into the My Account section while logged in, and you will see a ‘Cancel Subscription’ option. Follow the steps shown, and your membership will end once you reach the next payment date. Until then, you can use the service as usual or resubscribe if you change your mind. Just note that any promotional offers may not be available again if you originally signed up at a discounted price.
