You've decided to upgrade, so now what?
In order to activate your new subscription, you'll need to let Sling know you're upgrading, and enter your payment details.
It's not possible to upgrade from the mobile app at this time, so you'll need to login to your Sling account from the web, and then click on your name in the upper right corner for the dropdown menu where you can select "Account."
Then, select the "Billing" tab within your Account page, and you'll see the button to purchase a paid subscription:
After you click that, you'll be able to select which type of plan you want to go with, and enter your credit card details.
Please contact the Customer Support team if you have any questions, or if you are interested in annual invoicing rather than monthly!
